kernel_kore

Hi, I have some problems with a VM in XO-Server 5.79.3, here i detail it:

In a VM, after windows server update, I sent to restart server, but the server hang.
Then I try to restart with de reboot button in Xen-Orchestra, but nothing happend.
After that, I try to power off, but nothing happend.

At this point, the VM can't turn off, turn on, restart, etc.

When I try to start the VM, I have this error log:
Any Ideas?, thanls in advance.

Hi, thanks in advance.
I used the XCP-ng Center to connect to Host and restart the toolstack.
After that everything is going well.
Thank you very much.

Danp

Have you tried restarting the toolstack?

kernel_kore

@Danp Hi, and thanks for your response.

How do I do this?.
This procedure, doesn't have impact in the other VM?.

Thanks in advance.

There's a restart toolstack button in the host view (in the big action bar). This has not influence on running VM (but this will cancel any export/backup)

Hey, i got the same error message. Shutdown a VM want to boot from an ISO but that failed and now its always paused and i can not shutdown or reboot.

The error from my XO is "unspecified domain type".

Restart Toolstack helped to show the VM as not running, but on next try it ends up with the same error. Already tried via console with xe vm-shutdown or vm-unpause.

// Was able to fix it for me with:

Sounds like a XAPI bug, I think it's fixed in the next train of updates
