VMware is virtual machine software that provides a virtualized set of hardware (a video adapter, a network adapter, and hard disk adapters) to the guest operating system. VMware virtual machines become highly portable between computers, because every host looks nearly identical to the guest. In practice, a system administrator can pause operations on a virtual machine guest, move or copy that guest to another physical computer, and there resume execution exactly at the point of suspension. VMware's enterprise software hypervisors for servers, VMware ESX and VMware ESXi are bare-metal embedded Hypervisors that run directly on server hardware without requiring an additional underlying operating system.

I'm in a bind.  I had to reboot my switches connected to my VMWare and I've lost my NAS.  No matter what I try I can't get the NAS back on 2 servers.  I'm using 6.0 It sees the ISCSI adapter it just will not bind.
Enclosed are picturesbind 123.png4.png
I'm at my witts end.  Please someone help me figure out what's wrong.

I am using ESXI 5.5 and one of my hosts have disconnected from VCenter. The VM's are still running and accessible. I am able to connect to the Host through SSH. After logging in I ran the command vdf - h and the TMP file shows that it is 100% full. I have been trying to find a way to clear out is TMP folder so I can reconnect the host. I cannot reboot the host at this point.
I have tried restarting the services and this has not resolved the issue
I have tried to access the tmp folder to see what is running by using /tmp # du -h   and I am getting permission denied (I am using the root login).

I am looking for any help I can get to try and get this tmp folder cleared so I can reconnect to the VCenter. Thank you .

I use VMWare Workstation on my personal laptop to host a variety of Windows and Linux installs.  This includes hosting a Windows image of my customer's Windows workstations, which allows me to VPN into the company for various purposes.

In the past I've used a company ISO to build a VM, however recently the company has rolled out new workstations and with this they won't give me a new ISO.  I was able to pretty easily virtualize it though with the VMWare utility and have an image now that runs fine.

The problem is that the original image is on a 256 GB drive and now I have this 256 GB image as a VMWare guest.  Only about 25 GB of the disk on the laptop was in use though so there's a lot of wasted space.  I'd like to be able to somehow shrink down this guest image, but I can't find any way to do so.  I'm throwing away at least 150 GB of my person laptop's disk though because of this.

Can anyone describe any way to reduce this client size?  I've looked at shrinking the partition size of the image, but that doesn't seem to give me any way of shrinking the image overall.  Is the only way to possibly do this to go back to the original workstation they gave me and shrink that partition and then virtualize it again (or will the virtualization always use the size of the host drive regardless)?

We are running ESXi 6.5 and we have vms which are running 2012 R2.
The issue we are seeing is that we have around 80 Citrix servers on these vms and we send out  reboot request each Sunday via Citrix for all for all of these vms, but the issue we are seeing is that some of the vms shut down instead of resetting but never power backup while others reboot just fine. So we have to manually power some of them back on.
Is there  a setting somewhere that we need to change on the vms and or host so that when they get the command to reset that they do and don't shutdown?

Hi All,

I'm having an issue with my Windows Server 2016 cluster system.
it consists of 2 nodes, let say Node1 (showing as down) and Node2 (is up).

Node1 is ping-able to Node2 and vice versa, but not sure why it is showing as down.

The Failover Cluster Validation Report shows error only on the below CNO:

The cluster network name resource 'PRDSQL-CLUS01' has issues in the Active Directory. The account could have been disabled or deleted. It could also be because of a bad password. This might result in a degradation of functionality dependent on the cluster network name.

Hello Community

Some users in our VDI enviroment (based on vmware horizon view, linked clones Server 2016 with redirected profiles) have the following problem

Problem:
Icons in startmenu (startmenu and tiles) are missing. The icons disappears randomly. The shortcuts point to installed applications, folders and files or windows default apps like the paperbin

startmenu.png
The problem can be solved temporarly by deleting the icon cache with the follwing command:

  • ie4uinit.exe -show
  • taskkill /IM explorer.exe /F
  • DEL /A /Q "%localappdata%\IconCache.db"
  • DEL /A /F /Q "%localappdata%\Microsoft\Windows\Explorer\iconcache*"

Does someone have faced and resolved the same /similar issue?

Nothing special in the eventlog. We already created a new userprofile but the issue still persists

I would like to give a new user only Admin Rights for a few Servers residing in ONLY one Cluster.
So basically Admin Rights Only for One Cluster.  

How can I do this on vCenter 6.5?

I have an HP Proliant G8 server.  Dual 12 core AMD processors.  It has 94 GB of ram and 16TB of local storage.  I would like to  use this in our test lab.  I have attempted to install ESXi 6.5 update 2 (HPE build) to in installed internal thumb drive, using a external flash drive and a USB connected DVD drive.

I have rebuilt the flash drive twice, once using Yumi and once using Rufus pointing to the VMWare ISO file.
I have reburned the ISO image twice using ImaBurn.

In every case, the server boots without any errors, but indicates no bootable media available.

I have altered the boot device from internal to external USB and made sure it was enabled.

I have also altered the boot sequence to CDRom when trying it from the DVD player.

Never had this issue before.  Anyone have any idea.

Hi
I have 15tb storage arrays, I'm in 2 minds of whether to create VMFS or VVOL datastore? can someone please advise. my hosts and storage allow for VVOL.

secondly shall I create multiple VVOL/VMFS datastores or just one.

thank you

I have a virtual 2008 R2 server running on VMWare that got corrupt this morning. I can not open control panel or Explorer. I get the error message “the server process could not be started because the configured identity is incorrect.”

I can’t get to system restore.

I can get to a command prompt. I tried scf /scannow and got an error “Windows Resource Protection could not start the repair service.” I also ran chkdsk but that did not help at all.

I saws a post about changing the key HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID{Key in the error message I get} to interactive user but that was already set.

Anyone have any ideas on how to recover this?

I set up a Windows Server testbed and asked a question here:
https://www.experts-exchange.com/questions/29143184/Hyper-V-VMs-physically-on-separate-subnets-howto.html
In the midst of the discussion, I tried to set a static IP address for each of the two VMs that I had implemented.
I used a method where I used Advanced Features of the VMs network adapter and assigned a MAC address.
Cliff Galiher took exception to what I did and I took that advice seriously.

Later, I tried to set things back to what I thought had been suggested but doing this broke the testbed.
So, the testbed remains with what I did....

I should point out that in the original testbed, each Server VM was on a different subnet and had a separate physical NIC.

Now I'm setting up another testbed with the real Servers and similar Hyper-V VMs.
I need to make sure that the VM Servers have static IP addresses - as before.
I don't want to overthink this or to overdo it.  
So, what is the recommended approach?
In this case, the 2 VMs in the Hyper-V platform will be in the same subnet and I envision one physical NIC for the pair.
So, in that sense, it's just a little simpler than the original testbed.

Hello Experts,

I have a server that will not install the latest security update.  It looks like everything is going well, but it hits 97% installed and then fails.  I get the message that the server is reverting the changes and 15 minutes after two reboots, I can log back into the server.  In going through the logs I found the error code of 0x80004005.  Doing a quick search lead me to the article found at the following URL:
     https://blog.spaps.de/windows-update-failed-with-error-code-08x0004005/

The article states that diskpart showed the author's disk out of space.  At first I ignored the article and tried all sorts of other troubleshooting steps as Disk Manager showed my server has plenty of space.  After nothing else worked I went ahead and checked my disks with diskpart and I am in fact out of space according to diskpart.  A screenshot of both what diskpart is showing and what Disk Manager is showing is provided below:

Diskpart-DiskManager
I now think this is definitely my issue.  Here are my questions:
1.  Why is diskpart different than Disk Manager?
2.  How do I extend these partitions in diskpart?

This is a virtual server, so I can add more space.  Do I add space and then use diskpart to extend the disks?

Thanks,
Nick

In oue Dev Environment which has 3 ESXi 6 servers that use older NetApp running ontop version 8.x. I created a new volume, granted each host read / write and root access and ensured Unix permission are selected. No matter what I do I get the same error message in VMware "Cannot open file....." I have checked the IP in the export a number of times any they are correct. The vmkernel logs says it was denied by the NFS server but I do not know how. Also the hosts have other Lun mounted from this NetApp alraedy that are working.

I'm configuring a VMware vSAN  on a few Dell PowerEdge R720s with a PERC H710 Mini RAID Controller (embedded) running vSphere 6.5.  I'm trying to surface the drives (2 SSD and 6 HD) but there are restrictions on the H710 not allowing me to convert to non-RAID.  VMware documentation indicates that drives must be set up in a "pass through RAID" configuration.  So, do I get another RAID controller that allows for no-RAID drives or is there a way of creating Raid 0 drives or can I mirror the 2 SSDs (RAID 1) and RAID the other 6 HDs.  Maybe I'm old school but I tend to trust controller RAID more than software raid, but it's required so not sure I can get around it.

I just wanted to see if I could get some best practices for virtualizing a file server in respect to semi-large data volumes. Note that this is a small setup, there is no SAN or Shared Storage in play here, just a large direct attached storage RAID 10 array on ESXi 6.7

Aside from the actual virtual machine and the boot/OS volume, I was planning on simply adding an additional 2TB disk to the VM that would house all the shares. Is there anything else I should be thinking about concerning this (other than probably thick provisioning it for the best volume performance)?

Simple question I know, but just wanted to get some opinions.

Hi

We are going to upgrade our UPS on site.

We currently have a single Eaton 5PX and Eaton 5130 UPS running our single and only cabinet at head office.  We recently had a power cut which flagged issues.  These are the run time & load on the 5px and also a battery warning message.  We would now like to increase the wattage and run time, along with managing the UPS and also shutting down our on-premises vmware hosts if required.

We also have 2x old managed APC PDUs.

We have worked out that we have c6000 watts to cover.  Rather than buying a N=1 UPS at a steep cost are we able to use two 5px 3000 eatons splitting the load across the dual powered devices (switches, storage and servers) and use the 5130 for non-critical systems.
Is this possible?

Would you also replace the APC PDUs for eatons, would we requires x2 and how best to configure?

Thanks

I am looking at nested virtualization in our vSphere 6.0 lab.  I want to look at ESXi 6.7.  

When I create a new VM and select other, I only see VMware ESXi 6.5.  

Is there any issues with selecting this option and then loading ESXi 6.7?

This is a follow up to the “What vCenter Role allows connections to network adapters”  question

In managing roles and permissions in vCenter, is there a way to control the networks a user can add to their VMs ?

I am setting up a role in our Test and Dev vCenter to allow certain user to modify their VMs.  

Which permission / role will allow them to connect to network adapters assigned to their VMs?

I created a VM guest by virtualizing my company laptop.  I then copied this to my personal laptop and I'm running it in VMWare Workstation 15.1.  I used the virtualizer free from VMWare and pointed to by their product.  I deployed it on the company laptop, ran it, copied the results to my personal laptop via thumb drive and then opened it with VMWare.

Both my host and guest are Windows 10.

I can't copy and paste files between the guest and host and I'm guessing it's because VMWare Tools isn't installed (at least I think that's the issue).  When I to install them the option is grayed out and I can't.

Is there something special/different about an image that comes from a clone?  Neither had a DVD so neither can be fixed with the trick I've seen posted about playing with the CD/DVD options.

Vcenter esxi version 6.7.0.20000 Build 10244845

VMware ESXi 6.5.0 build-7388607

Is it safe to enable deduplication & compression on an already live in production 2 node VSAN?

We us NFS as our storage protocol and have seen very poor performance on our VM’s from time to time. On our SAN, the average latency is around 2 – 4ms which is ok. What I have observed is when our host our pegged at 95 – 100% CPU usage, our DAVG time goes up to 15 – 25ms. With that being said is the following state correct. With file level storage when the host is CPU constrained it will cause delays in the NFS calls to the SAN which in turn causes poor performance. In short, the CPU usage on the host has a direct result on NFS performance. This is not the case with block storage though correct?

I am having an issue with a Server 2016 Server will not boot up. Just spinning Circle. This server is run in a Vmware ESXi 5.5 Host. This server did not come back up from running updates last night. I can get into safe mode, but in regular mode, it will not boot up. I have let it running all day and I haven't gotten anywhere. I have looked on the web for this issue and i see similar posts, but no fixes have worked. We use an image based backup called Replibit. It works similar to Datto. I can virtualize this server on our backup server. Concerning problem is, I went back to last nights backup Before it updated windows and that backup is not booting up. Same thing. I tried to do a restore to my other ESXi 6.5 host and same thing. I even went back 1 month and tried to boot that image and same thing. I am at a loss here and this server is business Critical.

What I have tried so far:
Removing the Network Card from ESXi and other devices like CD ROM
Disabled Driver Signature Enforcement
Last Known Good

Since I restored this server to another host and i have backups, I can safely try anything as i can just restore back and try again. But it's a race against time. The original server i have still booting up on my ESXi 5.5 Host just to see if it will.  I am going to pull the event logs and post them here after I send this as I can get into safemode with networking. Any help is greatly appreciated!!

VMWARE 6.5 VSAN

My vCenter and ESXI host are all up to date with updates.

I am new to using VSAN in a VMWARE environment.

I posted this question on the VMware forum and got a nasty response not happy with them now.

Hoping one of you guys can help me.

I setting up the VSAN Cluster I had to modify my Cisco 3750 switch to change the MTU from 1500 to MTU 9000 Jumbo frames.

I also changed the Vswitches from MTU 1500 to MTU 9000
And all the VMKERNAL Adapters from MTU 1500 to MTU 9000

After I made that change my VSANDatastsore went from ZERO to 7 TB

Problem I have now is that I am unable to write to the vsandatastore.

I found this article

https://www.virtual-allan.com/vsan-error-cannot-complete-file-creation-operation/ 

 

I ran this on each host in the cluster, got the same results for all a ZERO

 
 vsish -e get /vmkModules/vsanutil/stretchedClusterMode
0

I checked the permissions on the vsandatastore and they match my other datastores.

I am trying to use this space for my Veeam Replication jobs they all failed to write to the VSANDatastore.

Any ideas on what I am missing here? any commands I can run to gather more details to help troubleshoot this issue?

Thank you

Tom
