I'm asking for the best way to replace VMware ESXi hosts with new hardware.
We currently have HP Dl380 servers Gen 9 hosts running ESXi 6.5 and are looking to go to HP DL380 Gen 10 ESXi 6.7
We have four 10 GB network Adapters in each server , each connected to different vSwitchs.
The new hardware will also have Four 10 GB adapters and will end up being configured identical to the Gen 9 server.
We are running vCenter Server Appliance 6.7.0.14000

What is the best way to install the new servers ? and end up with the same configuration as the old servers ?
Can I backup and restore the VMware configuration ?
Let me know your best experiences with accomplishing a replacement like this

Hello,

I have 3 DCs,2 VM DCs and  1 physical DC and I want to virtualize last physical DC.
To virtualize DC  infrastructure shouldn't be a problem
https://www.altaro.com/hyper-v/virtualized-domain-controllers-4-myths-12-best-practices/
but what about cluster environment
„In 2008 R2 and prior, a cluster wouldn’t start at all if it couldn’t contact a domain controller. This is no longer true in 2012 R2 and later. Even if the cluster service won’t start, both Hyper-V and VMMS.EXE will. With basic cluster troubleshooting techniques, you can bring a clustered virtual machine online without the cluster running. These are techniques that you should know anyway if you’re operating a Hyper-V cluster.“

I have 3 NOD vmware(6.0) cluster and I want to virtualize last physical DC.
Please give me some advice,hint,best practices,share your expirience…about virtual AD environment in vmware cluster.
Thank you

Hi,
 
 The "NVWatchDogService" service on our Windows 2012 R2 server stopped working,
task manager status shows this service "Starting" even after reboot.

There are two Event Viewer errors when stopping and restarting this service:

  Event Error 1.
Description:
Service cannot be started. System.ApplicationException: Failed to start java Service.
   at ShunraBootstrapperService.JavaStarter.StartService()
   at ShunraBootstrapperService.BootstrapperService.OnStart(String[] args)
   at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)

   Event Error 2.
Description:
Error while creating file: Access to the path 'C:\Program Files\HPE\NV\OpenJRE\bin\NVServicesJ.exe' is denied.

Suggestions are greatly appreciated.

Thanks,

When my customer runs her report from Excel 2016 64 bit, with 3 million rows, her CPU hits 100%. She is running this on a Windows 7 virtual machine, 12 gigs of ram, 130 gig drive, 2 VCPU (what ever that means) As per the customer this worked till last month. I did all the usual stuff, check off disable hardware acceleration, unchecked protected view, also created new local profile. Any suggestions?

I have a DC that is a VM and it keeps shutting down (every 5-10 days or so) with the error, "There is no more space for vitual disk "CN-000001.vdmk. You might be able to continue this session by freeing disk space on the relevant volume, and clicking Retry. Click Cancel to terminate this session."

I have to revert to an old SnapShot to get it to run again. Because disk space appears to be running out, I'm fearful of deleting the old SnapShot and creating a new one.

Any help would be appreciated!20190820_DataStore-1.PNG20190820_DataStore-2.PNG20190820_DataStore-3.PNG

Hi, I am using ESXi 6.0 cluster with 9 nodes and 2 SAN (MD3200 and MD3800) through iSCSI.
I am trying to move one particular VM to one storage to another.
Every time, about 94%, I got error "timeout error".
I tried with this solution:

https://kb.vmware.com/s/article/1010045

and raised fsr.maxSwitchoverSeconds  to 900, but I got same results.

This VM has just one disk (with one snapshot created last week).

Any suggestion?
Thankyou!

Hi,

In VMWare when we click on Snapshot, is the snapshot created represents the image at the time we click on "Take a snapshot" or when snapshot process is completed?

We have Few VMs running with mission critical Applications where Antivirus is not allowed  by App Owner
What else can be used here with min cost and better service?
vShield dependency with VC /Esxi Licensing ?
Can we use vShield Endpoint  ? if yes what all are prerequisites and cost estimation

VM Host CPU over subscription, if a VM host has 24 logical processors and has say 40 vcpu configured would you consider that oversubscribed? I'm not sure anyone does 1-1 right? this host is in a cluster and DRS enabled.

CPU Cores : 12 CPUs x 2.00 GHz
Sockets : 2
Cores per Socket : 6
Logical Processors : 24
Hyperthreading : Active

On ESXI 6.5 a VM has the error:
There is no more space for virtual disk 'abcd-02.vmdk'. You might be able to continue this session by freeing disk space on the relevant volume, and clicking Retry. Click Cancel to terminate this session.

How do I solve this issue?

Dear Experts

I have never seen this before. I have VM running W2012 R2 standard,¨

My NIC works normally when its address is received from DHCP.

When I assign this IP as static IP, it stops working.

Any idea why?

Thanks

We noticed that we can't open a remote console for a deployed VM from VRA web interface, we get the below error:

"Cannot connect to remote console. Verify that the machine is powered on and connected to the network."

The VMs are powered On, on Vcenter side the VMs look healthy.

This is what i have tried so far:

Ping from Host to vcenter where the VRA VM resides:
	[root@host:~] ping vcenter
	PING vcenter (10.93.104.30): 56 data bytes

Hi, I have a VM (VMware) Windows Server 2008 R2 Standard that become very slow during boot process ( > 15 minutes).
This VM has 500 GB disks (90% full), 16 GB RAM and 8 vCPU.
How can I determine root cause of this issue? Thank you!

Here is the situation:
I recently purchased a Dell server that had Server 2019 Standard pre-installed. Now it is my understanding that I can install Hyper-V and have 1 "free" install of Server 2019 Standard as a VM.
Is that accurate?

If so, where do I obtain the actual product key from?  

Thank you!!!

hi,

we just setup CentOS VM using hyper V in windows 10 enterprise, and we try to avoid the situation which we mix up the existing VM, should we just create a snapshot of the existing CentOS VM ? this can make sure the current CentOS VM can restore back by this snapshot ?

then how can I create the snapshot?

Hi, I have a cluster ESXi 6.0 with 9 nodes.
I noticed very bad performances on different VMs on my infrastructure.
According to resources utilization on entire cluster, I would exclude RAM / CPU issue.
I suspect there is some issue on storage side (we use PowerEdge MD3200 / 3800) through iSCSI.
I ran esxtop on some hosts, occasionally I noticed very high DAVG / KAVG values.
My question is: what would you do next?
Through esxtop I can find the "affected" lun.. isn't there a more efficient way to identify the VM (or VMs) that are causing performance issues?
Thank you

New server for a site of approx. 30-35 users.  Will be running 4-VM's in Hyper-V on W2K19 Server OS (VM's- DC/Print Server, Remote Desktop Server (minimal use), 2-Application servers). Possible future File VM (would need more MS licensing).  Purchasing a new HPE DL380 Gen 10 Server as the Hyper-V Host.  2-processor (24-core), 128GB RAM, P816i-a SR Gen10 Controller with 16-open SFF slots.  Thinking OBR RAID 10, (8) 600GB SAS 10K 12Gb/s drives plus (2) hot spare.  Extra bays for future growth.  Will have 1-Array with 2-logical drives- one for Host OS and one for the VM's. I am researching SSD options from HPE as well but looking to justify cost to owners.  

Question- Should I be installing SSD in this configuration?  Read, Write or Mixed use?  Site typically runs servers 6-7+ years.  SATA or SAS SSD (leaning towards SAS SSD if we go SSD route). Trying to justify the extra cost of the SSD setup.  The SSD SAS 12GB/s option from HPE is pricey.

Thanks in advance for the input.

I have a Server 2016 - it's actually a terminal server with a lot of apps on it.  I can not get an updates on it. I think the last time it updated was sometime early July, maybe even June.  I've tried deleting the software distribution folder and re-registering it with my wsus server but still not luck.  I've tried Sconfig and that doesn't work either.  I even tried downloading the updates manually and installing them and that isn't working either.  There is no information in the event logs and the update history isn't any help either.  I've tried dism too and that hasn't given me any information either.  This is a VM and it's heavily used.  I'm out of ideas.. Any suggestions?

hi,

any easy to follow procedure to setup CentOS VM on windows 10 and install MySQL standalone on top of CentOS VM ?

Good day,
We have a VM host that runs two server machines.  The first is the DC/FS and it works great.  The second machine is a terminal server.  It constantly is freezing on the users and it is getting frustrating.  Here is some info:

Host machine is running Server 2016 Standard.  Its specs are:

HPE Proliant DL380 G9
Xeon E5-2620 v3
32GB RAM
RAID 10 for the virtual disks

Server is stable, no issues.

The host machine allocates a large portion of RAM to the DC and the TS.  The DC currently has 8GB and 8 virtual processors.  The TS has 10GB RAM, and also 8 virtual processors.  Originally I had the TS with less RAM and processors, but in trying to fix the freezing issue, I increased the resources.  I plan on bringing them back down.

The TS has only 3 users signing in.  They use the same domain account to log in to the server.  The TS is configured to allow the same user to log in multiple times.  It is light usage.  The TS exists to run only one program.  While using that program, the users may open Word or Adobe, but not much of anything else.  About 4 or 5 times a day, the server just stops responding to that user.  The other users logged in do not experience the same.  It will just spin and spin.  The remote connection never breaks.  Frustrated, they just click the x on the top blue ribbon, and re-log back in.  Then its totally normal until it freezes again.  

During the freeze, the internet is working normally, the others users aren't affected.  A VPN …
