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.

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

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

Hello,
We have one VMware VM that is getting the following error message:
{Delayed Write Failed} Windows was unable to save all the data for the file . The data has been lost. This error may be caused by a failure of your computer hardware or network connection

Is there something we need to look at or can this error be ignored because it is possibly a generic error?
From what we can tell, there doesn't seem to be any real issues with accessing data from the server.
The server is running 2012 R2
Thanks

Hi,
I have VMWare vCenter Server Virtual Appliance 6.0 U3. I want to upgrade it on VMWare vCenter Server Virtual Appliance 6.5 U2.
Different versions of ESXi hosts (starting from version 5.0 and ending 6.0) are connected to the current vCenter server 6.0 U3. Will the current versions of ESXi hosts be compatible with the new version of the vCenter server (6.5 U2)?

we currently have a vswitch with 2 x qsfp NICs that we use with an Equallogic SAN with multipathing with 2 x vmkernel ports on the same vlan. Is it possible to add a second pair of vmkernek ports  to the same standard vswitch, on a different vlan, connecting to different san?

We have vcenter 6.5 in our main office and would like to add a remote office's ESXi host to the main office's vCenter.
I can add the ESXi host, but it shows as disconnected. I am unable to manage any vm on that remote site.
The remote ESXi host is version 6.0 and i created a separate datacenter folder.
I would appreciate your input on this.

Hi,

We have an 18TB VVol, and want to allocate 3 TB for the file servers. The rest of the volume will be used by other VM’s.

Can we create a 3TB volume inside the VVol so the file servers can use this space? Alternatively, shall we shrink the VVOL and allocate the space to the fileservers the free space?

Whats the best way to handle this as I know VVOLs work different to  VMFS

Thanks

Hi Guys,

I increased the storage on a VMWare ESXi 5.x server by adding another disk to the server.

I managed to expand the storage of the Datastore.

I am now trying to increase the disk provisioning space for the virtual machine, but I seem to be having some challenges.
I powered off the virtual machine, but the Disk Provisioning section stays grayed out.

I exported a VM to an OVA then imported at our secondary site. It is a View Golden Image. I did not change the name or do any sysprep/quickprep but did power it on to make sure I could access it. I then created a snapshot and set up a View pool in that site that mirrors the production site.

I went to update group policy on the original golden image and received errors about LDAP binding and authentication to a DC (event ID 1006 error code 49 and event ID 1129 error code 1222) as well as a netlogon error (event ID 3210 which specifically mentions this error may be caused by another machine with the same name on the same network).

I then changed the name of the secondary site computer and rebooted. After waiting about an hour or so, I tried to update group policy but received the same error. I also get the errors on the primary site's computer.

Any help is much appreciated.

Hi Guys,

I need to increase storage on a VMWare ESXi 5.x server.

In ESXi 6.x logging onto the server, I am getting the option "increase capacity" under storage, devices.

I am unable to find this option in ESXi 5.x

Was this option available in ESXi 5.x ?

Hi,

I have a server running Vmware ESXi on a Dell Power Edge R510.  It's setup with RAID with 4 10K SAS drives.  The capacity is 1.64 TB.  All 4 of the SAS drives have been recently replaced.  I'm not at all familar with Vmware as I've always used Hyper-V and other VM solutions.  There's only on VM setup running Server 2016.  Xeon X5675 (8 processors) with 48 GB RAM allocated to the VM.  The host has 64 GB RAM. 12 CPUs.  A software vendor (I'll call vendor A) recently upgraded their software on the server and it looks like they're using SQL 2012.  They have another db on the server that also uses SQL 2012 well call from vendor B.  There were a bunch of log errors from vendor B's database.  10 GB worth.  They cleared them but their storage benchmark said that the write speeds to the storage were around 22 Mbps.  On 10K SAS drives that seems excessively slow.  I've logged into the ESXi navigator and have spent a few hours going through all of the settings in there.  Is there a way that I can test if all four of the SAS drives are working properly?  Under Storage, Datastore01 and Monitor, there are a few lines from June 13th (nothing listing anything after that).

We are using vCenter 6.5 to manage 8 ESXi 6 hosts. The cluster is set for fully automatic and the most aggressive DRS threshold. When our hosts are stressed DRS will not make recommendations and we have to manually move items around.  I understand that DRS will not move a VM unless the move will improve things above a certain threshold. Also all impacted VM's to not have an ISO mounted to them. This is for a VDI cluster and wondering if using the control CPU over commit or memory balances based on load would help. Finally there are no DRS faults.

Thoughts?

Any feedback so far on the most recent updates for vSphere 6.7?  I'm looking at updates from Esxi670 - 201903001 to Esxi670-Update02.  These would be applied to Supermicro hardware.  Just looking for any gotchas that would suggest waiting.

Thanks!

I am running VMware® Workstation 15 Pro 15.0.4 build-12990004. The host PC is running Windows 7 Professional, 64-bit 6.1.7601, Service Pack 1

There is a Windows 10 Professional 64 bit O/S VM on an internal SSD disk (Version 1803  OS build 17134.706) which is running low on disk space.
I plan to add an additional (larger) internal SSD disk and want to move the VM onto the new disk. The prospect of having to un-install and re-install the software development environment is a bit daunting which is why I would like to move the existing VM.
Will there be any issues with Microsoft Licensing/Validation ? Are there built- in capabilities in VMware Workstation to provide for moving a VM from one disk to another internal and retaining the same Host System ?
