Hyper-V VMs in Stopping Critical State

Reid Cooper

Have you tried going into the task manager and killing the processes of the VMs?

Alket_tux

You're killing VMWP.EXE ?

Alket_tux

@wirestyle22 yes

Reid Cooper

Is there anything running on your Hyper-V host other than the Hyper-V utilities? Lots of things can cause Hyper-V to pause if installed alongside.

wirestyle22

@Alket_tux It successfully terminates the process but still shows itself as stopping critical? What does 'nothing happened' mean?

Alket_tux

@wirestyle22 i rebooted the server, and i have been 30 minutes now just seeing shutting downservice: hyper-v machine management*

Alket_tux

@Reid-Cooper no, nothing, team viewer only

wirestyle22

@Alket_tux Can you turn off that service and attempt to reboot?

Alket_tux

@wirestyle22 it means that the state of the vm is running again, it just does not show the resources allocated to it

Alket_tux

@wirestyle22 i tried to do that, but it did not stop, it remained in stopping state.. and in the logs it showed that the vm-s were running so this service cannot be stoppoed

Alket_tux

i have not inserted integration services manually but yesterday everything worked fine..
by the way i have emulex nic's and in google i found that it might be a problem

wirestyle22

@Alket_tux I also found NIC related issues listed

Alket_tux

@wirestyle22 i found some kb related solutions but haven't applied yet

wirestyle22

@Alket_tux From what I've been reading they didn't help. Hopefully yours is different. What VM's are you running? OS's and everything

Alket_tux

@wirestyle22 windows server 2012 r2 my primary server
hyper v role on top of it
6 ws2012 r2 vm's created

Alket_tux

@Alket_tux all working fine until yesterday, when i left my office and let windows update
on all servers

Hello guys,
i ve been in trouble with hyper v on ws 2012 r2.. the issue is that when i restart my server Hyper-v Virtual machine management service takes an eternity to stop, so i hard reboot.. after that my machines are in runnig state.. also when i try to shutdown my vm-s, their state goes to stopping critical.. any ideas would be helpful..
thanks

When you shut down a Hyper-V server, the default settings for all of your VMs is to save the state of the VM. After that, your server will shut down. Depending on the number of VMs you have, it could take a little bit to save the state of all of them. It has to write the memory to disk, etc. Also, the default startup option is to start the VMs if they were started when they went down, which is why they are back up when you boot up your hypervisor.

If you are killing your server during this process, you are hurting your VMs. This will cause critically stopped states. Hopefully they are .vhdx disks to help prevent corruption.

Oh I misread the OP. I thought he originally shut this down properly. @Alket_tux you just attempted to reboot the hypervisor without shutting down the VM's initially, am I reading that correctly now?

Alket_tux

@Tim_G i did stop my server forcefully a couple of times,
