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.

is it really Best practices and better, to use Thick Provisioned Virtual Disks on VM's that will be Microsoft SQL Servers?

 Also is 6GB of memory too low for a virtual SQL Server?

I am asking these questions because in our current environment i am noticing alot of VM's that are SQL Servers with Very little ram and also noticiing the Virtual Disks are all Thin.  

Our LUNs on the SAN side are all thick just an FYI.

From my understanding, i was told always use THICK for SQL, and i have never seen a sql server with only 6gb of ram.  I know there are ways to have SQL use less ram from within SQL itself.  

Just want a confirmation on the best practices, and real life experience.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

I have an environment of VMWare 6.5 hosts running on HP bl460c servers in a c7000 enclosure. All 16 servers have two vmnic's dedicated to iSCSI, and attached to a DS which is dedicated for storage traffic. These vmnic's are bound to vmk adapters which are in turn bound to the iSCSI software adapter on the host. The server nics are connected to Cisco switches via the passthrough interconnects on the enclosure.

For my storage device, I have a NetGear ReadyNAS 4312 with four 1Gb interfaces. I have configured these into dual bonded nics and both bonds are set with Layer 2 LACP modes and configured channel-groups on the Cisco switches. The bonds were assigned IPs, the vmks, were assigned IPs, and the software adapter was configured to discover the iSCSI LUN on the appropriate IP addresses.

During the original configuration, all MTUs in the path were at 1500. All 16 servers saw the storage and it was presented as a datastore to the cluster for which it was intended. All seemed well, but once the VMs were all running on the datastore, we began to have latency issues and significat lag when interacting with the VMs, whether by SSH or the console. As a test, I moved a couple of the trouble VMs to a different storage and the problems were eliminated. I knew that jumbo frames were supposed to be best practice for iSCSI but didn't want to shutdown the entire environment in order to configure and bounce all the switching but after these problems, and reading several papers on the …
I am trying to install VMWARE from the linux bundle on my Manjaro Linux system.  I got close with the Manjaro Forum (and it is still out there).  I need to find the kernel headers my kernel is using.  My kernel is up to date but I can not find the header files for it so I can tell VMWARE.  The message I get is below.Output of VMWARE install bundle
2 Windows 2012 R2 Data Center NLB IIS DFS/R URL Rewrite
2 Windows 2012 R2 Data Center Web Farm IIS DF/R
VMware ESXI 6.5

I can not access my web sites externally.   Internally using the VIP of the NLB servers it works.

When I modify my Meraki router to point to the VIP of the NLB no one can access my two sites.

If I change the meraki router to point to the physical address of one of the Web Farm servers that works also.

I need to be able to access my web farms thru the NLB servers

Thank you

I am undecided on whether doing Windows clustering (WSFC) used to be MSCS inside VMWare or not.  I need a way to monitor my application and windows services particularly.  I am not aware of a way that VMWare can monitor windows services and restarted them.  If I do windows clustering inside VMware, I am concerned about the complexity and losing some of the VMware HA features.  Any thoughts or advice on the subject is greatly appreciated.
I am using vCenter ESXi 6.0.
Since I ran out of space on VCSA due to very big audit.log file, I followed this URL:

I changed root password, and rebooted vCenter Appliance.
I am unable to access through vcsa.
In web interface, I get error:

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http20NamedPipeServiceSpecE:0x7f9ab7e2ac40] _serverNamespace = / _isRedirect = false _pipeName =/var/run/vmware/vpxd-webserver-pipe)

Even with vSphere client (the server could not interpret client's request)

How can I solve this?
Thank you
I have Veeam backup and recovery and was wondering why I received the email message after I added disk space to one of my VM's using VMWARE.  I added 50 GB and then rescanned the drive and increased the drive space.  Does it always delete all restore points when you do this?  I thought I've increased disk space before in VMWARE and did not see this message.
Can we identify Vcentre name from VM(2003 OS)?

Dear Experts, we purchased Disk enclosure HPE 2050 yesterday to expand the storage capacity of SAN storage controller HPE MSA 2040.

We connected 1 SAS cable from OUT port of 2040 to IN port of 2050. After that, we turned on the 2050 device and add disk group, built RAID6 but it seems like take longer time than expected. Moreover, we got the "Degraded" status on Disks information, so is it normal? Can you suggest please? Should we connect the other SAS cable between 2 devices?


I got a big problem with vmware workstation 12.5.9 build-7535481:

In snapshot manager I wanted to delete a snapshot.

A message has occourred that there is not enough disk space to do this.

Now the snapshot is not longer visable in snapshotmanager.

The snapshot is not visible running:
C:\Users\hhussy\Documents\Virtual Machines\MONTEVELO3>"c:\Program Files (x86)\VMware\VMware Workstation"\vmrun listsnapshots montevelo3.vmx
Total snapshots: 0

The snapshot-chain seems to be fully functional, because the virtual machine is running correctly.

I am in the process of upgrading my VMware vCenter Server from 5.5 to 6.0.  This is my first attempt at upgrading a vCenter Server so I am flying a little blind here.  When I begin to run the upgrade, I receive the following message:

"Warning: This vCenter Server has extensions registered that cannot be upgraded to or may not work with the new vCenter Server.

VMware vSphere Update Manager Extension on

Is this something that I need to be concerned with or is it normal when upgrading from 5.5 to 6.0?


New setup of 2 Vcenter Servers  (6.5 version) across 2 sites.

Both Vcenter are setup using  Embedded Deployment  ( Vcenter Server and Embedded Platform Services Controller )

how do i link the 2 Vcenters  in embedded link mode.

(we have VMware vCenter Server 6 Essentials for vSphere and VMware vSphere 6 Essentials Plus for 1 processor licenses respectively.
 I created a VHDX file from Windows 2012 Server running as VM on ESXi Host. Then I copied the VHDX file into the Virtual Hard Disk folder in Hyper-V 2016 Server and created  a VM using existing VHDX file, assigned RAM, CPU  and Virtual Network Adapter. When I start this VM, it only shows a blinking cursor at the beginning and stays that way.
 I have tried Legacy Network Adapter and tried to press [F8] to start in safe mode, but to no avail.
 What else can I try?

Assigning Physical NICs to Vmware port groups

If I understand when you create port Groups you assign them to Physical NIC will carry that traffic.

Correct me If I am wrong ,
I believe when creating Virtual Machines Port Groups you can assign them any available Physical NICs except for the NIC that will be assigned to the Storage and the one that will be used for Vmotion . At least , if you make a mistake and assign VM port group to the same NIC that you assign to Vmotion, it will still work , but not considered optimal , but if by mistake you assign it to the NIC that is connected to the Storage, then it will not work.

When creating Vmkernel port group for storage , I believe you will have to know prior to assigning a Physical NIC,  the name of the Physical Port.
example: Let's say on the ESX host,  you connected port 4 to SAN switch. So you will have to take note of that , so that when you create  Vmkernel for storage  you will assign Physical Nic4 to Vmkernel for storage

Correct ?

Thank you
Is there a way to determine which VMs on a host have a CD drive connected besides going to each VM? A host here will have between 40 and 150 VMs so it's a pain to go to each VM.

My reason for this is that when I do upgrades I need to put the host into maintenance mode and undoubtedly there will be some using a CD drive. This prevents vMotion but I don't know until the VM list shows the VMs left that couldn't be migrated. I then need to go to each one and see if it is due to the CD drive. Once confirmed, I need to disconnect the CD drive to continue.
Can an x86 appliance running ESXi from dell work on Cisco Viptela or Nuage SDWAN plaform? Aaron Tomosky is most qualified to answer and he is my local EE Guru.

First of all, let me say that I'm primarily a VMWare person, and have very little experience with Citrix except for the situation I'm describing in this post.

About 2 years ago, we signed a client who is using Citrix Xenserver on three host machines.  Two are running Xenserver 6.1 and one we upgraded last year to Xenserver 7.0. As we had planned from the beginning, we want to migrate all of their VMs from these three Xenservers to two host machines running VMware.  Their VMs are all Windows 2008 R2 except for one Windows 2012 R2 that we added last year to run SQL. They currently have two servers running Citrix Xenapp 6.5, and these servers are extraordinarily underutilized.  The reality of the situation is that the Xenapp capabilities are only being used by a few firm employees to work remotely occasionally at night or on weekends.  

My migration plan's end result would be two hosts running the latest version of ESXi with a vSphere Essentials license. I have done a lot of research and found lots of posts and helpful information on the pitfalls of migrating Citrix VMs to VMware, so I think I'm OK on that portion of the migration.  However, if anyone has any very recent experience with this, i.e., migrating to ESXi 6.5 or 6.7, and has something to add specific to those versions of VMWare, I would be glad to have the extra input.

I have some questions regarding migrating the Xenapp servers:

1.  Are there any issues running Xenapp on Windows VMs hosted on VMware?
We have a VSA running on a standalone esxi6.0 host.  The vsa is v6.0.0.30800 Build Number 9448190.
Its ran out of space and cannot log into it see attached.
Deploy new VSA?

I have a 5.5 cluster on a physical vcenter. I also have a 6.5 VCSA with one existing 6.5 cluster.
The end goal is to have a new cluster on the VCSA housing the current 5.5 hosts and then upgrading
the 5.5 hosts to 6.5.

Is this process as simple as removing the 5.5 hosts from the physical vcenter, creating a new cluster
on the VCSA, dropping the 5.5 hosts into the new VCSA cluster then upgrading the hosts??

Windows 2012 R2 Data Center
VMWare ESXI 6.5

I built 4 Windows 2012 R2 Data Center VM Servers.

Two Running NLB IIS URL Rewrite etc.      2 Nodes

Two others are Web Servers IIS  

Why I do    which is the Virtual IP Address on the NLB Servers
I get the default web page on port 80     that works great

I have other web sites on different ports
When I try to access them I get  

This website could not be found.


On the NLB configuration I added port 9080  

How do I get to my other sites using the virtual ip address?

Happy new year

Thank you

Old SQL server had major melt-down with controller failing as well as 2 HD in the raid 5 array.  So, now we do not have SQL databases for our VMWare 5 environment, nor do we have a good backup (nearest backup file is 8 yrs old...).  How can I create new databases on my new SQL server and get my composer running again?  View composer will not start and gives event 1000 error, Error getting configuration info from the database.  My VMs are still running on my ESX servers OK for now...

I'd like an expert to confirm that I am able to reboot a VMware Horizon View vCenter appliance without affecting operations of the four hosts it manages or the 80 or so virtual desktops in use.

I am doing this in an attempt to troubleshoot logging in as root. There are 12 failed login attempts recorded. The password in the company's password safe is not working. I tried 5 or 6 times (a few different passwords after the one in the safe didn't work) and a colleague tried as well, thus getting us to 12 failed attempts. I am following the directions here https://www.sneaku.com/2015/06/12/vrealize-operations-manager-6-0-root-account-locked/ as this vCenter appliance is 6.0. Though not vRealize Operations, I suspect the steps are the same.

Further, I am trying to login as root in order to run a shell so I can check the VMware vCenter workflow manager service and also disk space as a new vm pool I created fails to power on any of the new VMs and gives an error stating a general system error occurred connection refused. Troubleshooting that error led me to the aforementioned service and disk space as possible issues but need a shell to get that info. I am not able to run shell as administrator (receive permission error after successfully logging into the appliance with the administrator account). Then, if it ends up being one of those causing the error, fixing it so I can power on these VMs.

Whew, anyway... thanks.

I'm upgrading a cluster of hosts to 6.5 and wondering if it would break anything if I rename the cluster to 6.5. At the moment its 5.5?

Its an easy process, just wondering if things like Veeam backup will stop working


I have a question regarding VEEAM Backup. We have many vSphere VMs which have terabytes of data. The typical backup strategy is to backup the VMs to disk and afterwards to tape as I know. We have enough space on the backup server to store the full backups but not for the incremental.

So I want to store the full backups on tape and afterwards delete it from the backup server. But VEEAM can not find the full backup anymore, so it starts a full backup instead of the incremenal. Is there a way to achieve what I want or are there any better strategies?

Any suggestions? Thank you in advance.


I have VMWare 5.5 and I have 3 Windows servers. Is possible to create a virtual disk and share it to all 3 servers?

For example I create 100 GB disk and add photos and pdf files. Can I link this disk to 3 different VM servers or  for this case I really need to create a shared folder in a Windows server?
