how do you reboot your linux VMs in hyper-v?

[matteo nunziati]

@DustinB3403 because the machine shuts down but then it doesn't boot! it is like if you issue shutdown without -r.
This is the same with reboot or so. Also because all this commands are symlinks to systemctl.

there is something broken in the way hyper-v vUEFI is managed on ALL my VM.

[DustinB3403]

@matteo-nunziati curious...

[DustinB3403]

So if you did issue a reboot from the management interface, the VM just shuts down. Rather than actually rebooting.

Seems like a huge failure there if that's true. What hardware is hyper-v installed on?

@DustinB3403 said in how do you reboot your linux VMs in hyper-v?:

Or why aren't you able to reboot via the Hyper-V management interface?

what's this? I just have the "shutdown" button on the hyper-v GUI (win 10).
also if I enter a remote session in powershell and issue:

Restart-VM -Name VM-NAME-HERE

the machine shuts down it doesn't restart!

HPE DL380G9

I suppose something is broken in my setup: it is not possible people did notice this basic item!

According to the HPE HCL the hardware is fully supported...

Is anyone else experiencing the same results?

found anything on the web, going to call HPE support... but I'm a bit in a hurry. hoped for a fast solution on-line

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.

[matteo nunziati]

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.RestartVM

And 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.RestartVM

Not 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-as

But this is a no go for remote administration from within the VM. Need to sort this out

[matteo nunziati]

even tested a gen1 VM: not different.

[matteo nunziati]

ok, just got that Restart-VM does an hard restart (removes the plug). just forget it!
still missing an answer...

[Obsolesce]

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?

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

ubuntu has them built in. windows vms don't need...

I was thinking about reboot my win10 machine with hyperv and test there...

[dbeato]

Do you have the Linux Hyperv Agent updated?

@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...
