I've not heard of anyone having this issue. You might have something unique here.
yes. until it was ubuntu I was thinking about something strange in the vUEFI. but even win over win...

NOT what you want in IT. I'll be waiting to see what the problem is.

If the VM does not start at all, then what is in the container won't be the issue.

mmm... got this:
Restart-VM -Name zi-erp-as Confirm Are you sure you want to restart virtual machine "zi-erp-as"? [Y] Yes [A] Yes to All [H] Halt Command [?] Guida (il valore predefinito è "Y"): Restart-VM : 'zi-erp-as' failed to change state. + CategoryInfo : NotSpecified: (:) [Restart-VM], VirtualizationException + FullyQualifiedErrorId : OperationFailed,Microsoft.HyperV.PowerShell.Commands.RestartVMAnd the machine just stops.
Now performed a sequence of start-restart with no idle, just waiting in VM Manager to see the CPU go down and then fire the restart. So far so good... really weird. Let's the VM stay idle for a while and retry!
Yep! if the machine stays idle for a few tens of seconds everything go nuts:
Restart-VM -Name zi-erp-as Confirm Are you sure you want to restart virtual machine "zi-erp-as"? [Y] Yes [A] Yes to All [N] No [L] No to All [?] Guida (il valore predefinito è "Y"): Restart-VM : 'zi-erp-as' failed to change state. + CategoryInfo : NotSpecified: (:) [Restart-VM], VirtualizationException + FullyQualifiedErrorId : OperationFailed,Microsoft.HyperV.PowerShell.Commands.RestartVMNot this specific error but when people get this "change state" suggestions are to rebuild the machine
but those are all brand new.Apparently this is not the case with:
Stop-VM -Name zi-erp-as; Start-VM -Name zi-erp-asBut this is a no go for remote administration from within the VM. Need to sort this out
-
even tested a gen1 VM: not different.
-
ok, just got that Restart-VM does an hard restart (removes the plug). just forget it!
still missing an answer... -
So just the fact that you are running it as a VM makes all the difference?
If you run it on hardware, can you reboot normally?
Is it just with Hyper-V? Have you tried it on other hypervisors?
What happens if you install the latest actual LIS drivers from Microsoft?:

I never have any problems. I just did this.
Hyper-V Server 2012 R2 with a CentOS 7 guest in a Gen 2 VM.

you mean linux or windows? well yes never got issues on HW. but don't know on THIS HW!

same linux machines on kvm run perfectly and autoreboot at every update

https://www.microsoft.com/en-us/download/details.aspx?id=51612ubuntu has them built in. windows vms don't need...
I was thinking about reboot my win10 machine with hyperv and test there...

Do you have the Linux Hyperv Agent updated?
https://technet.microsoft.com/en-us/windows-server-docs/compute/hyper-v/supported-ubuntu-virtual-machines-on-hyper-v -
@black3dynamite @Eltolargo @Tim_G latest kernel and tools are installed from the HWE stack. this doesn't help. just tried again from a VPN to my office. Also hell win2012r2 doesn't reboot in hyper-v 2016.
monday I'll reboot the server from within the server room, with a monitor attached. let see if something strange happens even at hw level... -

Looks as if there is more issues with that server than just VMs restarting. Are there any pending updates on it?
-
@Eltolargo no just a windows defender update pending. server has been restarted after last update batch.
looking now at ubuntu VM in the last reboot I see this:
reboot system boot 4.8.0-41-generic Sat Mar 25 18:21 still running reboot system boot 4.8.0-41-generic Sat Mar 25 18:48 still running reboot system boot 4.8.0-41-generic Sat Mar 25 15:15 still running reboot system boot 4.8.0-41-generic Sat Mar 25 15:11 - 15:14 (00:03) reboot system boot 4.8.0-41-generic Sat Mar 25 15:10 - 15:11 (00:00) reboot system boot 4.4.0-66-generic Sat Mar 25 15:00 - 15:11 (00:10)3 sessions still running! bah this is for sure something broken...

You have never shown your Hyper-V configuration.
-
@JaredBusch yes... Err... what conf? The vm conf (always the same) or the hypervisor itself?
-
Disabled hyperv time services and forced linux rtc to utc. Now monitoring drifts ( never say never). but win2012r2... Don't know..

I know it's built in. But I would still try the latest from Microsoft as a troubleshooting step.

@Tim_G
The downloads from Microsoft is for Red Hat and CentOS. For Ubuntu, installing linux-virtual package is all that is needed.
