I can confirm that the "reboot" action is non-functional.

I cannot yet confirm that this is a regression.

[Dustin Kirkland  (kirkland)]

Okay, I don't think this is a regression from Intrepid.

In my Intrepid virt-manager, I do not have a "reboot" action available, that I can find. I do have a "shutdown" button, which, like jaunty, does not work.

Perhaps Jamie meant that this has regressed from earlier in the Jaunty cycle?

In any case, while it's highly annoying and unpolished that we have non-working shutdown/reboot buttons, it's not release critical, IMHO.

Description of problem:

I receive this error when I press shutdown button

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 523, in reboot_domain
    vm.reboot()
  File "/usr/share/virt-manager/virtManager/domain.py", line 569, in reboot
    self.vm.reboot(0)
  File "/usr/lib64/python2.6/site-packages/libvirt.py", line 392, in reboot
    if ret == -1: raise libvirtError ('virDomainReboot() failed', dom=self)
libvirtError: this function is not supported by the hypervisor: virDomainReboot

Version-Release number of selected component (if applicable):

qemu-0.10-8.fc11.x86_64
virt-manager-0.7.0-4.fc11.x86_64

Expected results:

I like to be able to power off and reset a virtual machine using shutdown button, without receiving error message.

[Mark (mark-redhat-bugs)]

Yep, this is a known issue:

Moving to upstream bugtracker

[Steve Beattie (sbeattie)]

Based on Dustin's comment, I've removed the regression-potential tag.

[Mark (mark-redhat-bugs)]

Ryan Harper posted a patch to add the qemu side of this:

[Mark (mark-redhat-bugs)]

Okay, moving back to Fedora/rawhide and putting on F12VirtTarget

[Mark (mark-redhat-bugs)]

AFAICT, the conclusion from upstream was that libvirt should do system_powerdown followed by polling via info status followed by system_reset

Any update on the status of this bug? The discussion on the Ubuntu dupe [1] of this bug has been lively, lately.

We're curious if libvirt might simply implement "reboot" by sending "ctrl-alt-delete" to the guest. It seems that most Linux and Windows operating systems will handle ctrl-alt-delete as a warm reboot fairly consistently.

[Daniel (daniel-redhat-bugs)]

I most/many Windows, Ctrl-Alt-Delete is a shortcut to bring up the login dialog, not reboot, so its not really viable.

[Dustin (dustin-redhat-bugs)]

Bummer. I guess it's really been that long since I used Windows. I swear ctrl-alt-delete used to reboot Windows...

[Daniel (daniel-redhat-bugs)]

Win 3.1 & Win 95/98/XP derivatives treat it as a reboot. Win NT and 2k, 2k3, 2k8, Vista, 7, derivatives treat it as a logon signal.

[Norberto Bensa (nbensa)]

This is fixed in Maverick.

[Joel Duckworth (joel-jpd)]

Running Lucid & qemu-kvm you can get the shutdown feature to work by installing acpid on the linux guest, but this doesn't fix the reboot option. Just FYI

[Fiodor Kupchik (ferimy)]

this is not fixed in Maverick as I can't reboot or shutdown VMs
very annoying

[Serge Hallyn (serge-hallyn)]

Fyodor,

please file a new bug with more details about your host and guest setups, and
exactly what you did. Given confirmation from others that the bug was fixed in
maverick, if you are finding it broken again then it is likely a regression.

[Andreas Ntaflos (daff)]

Serge,

why do you think this bug has been fixed? Nowhere is it confirmed that a fix has been released, not even the associated Red Hat bug has seen any activity in months.

[Serge Hallyn (serge-hallyn)]

Hm. Comment #5. Sounds like that one is simply wrong.

[Fiodor Kupchik (ferimy)]

Serge,

I think there's some misunderstanding. When I say - I can't reboot - I mean that it cannot be done despite the state of the VM and the fact of loaded OS or not. Every time I need to shutdown or reboot VM which does not support ACPI or just hasn't loaded OS I have to use kill program to send SIGTERM to the KVM process. I don't think this is the bug in Ubuntu package - this issue should go to upstream.

But saying that this issue fixed is wrong as the title states that by pressing button I should expect reboot or shutdown and don't care how it was done in code - via invoking kill prog via ssh or by the way of managing guest ACPI functions.

I think that there is no big problem to add two more buttons in GUI - force shutdown (kill specific KVM process) or reboot (kill and re-run).

I also faced this message on lucid using :

  virt-manager 0.8.2-2ubuntu8

Thank you Joel Duckworth. After installing acpid in the guest shutdown works.

    Support reboots with the QEMU driver

    For controlled shutdown we issue a 'system_powerdown' command
    to the QEMU monitor. This triggers an ACPI event which (most)
    guest OS wire up to a controlled shutdown. There is no equiv
    ACPI event to trigger a controlled reboot. This patch attempts
    to fake a reboot.

[Alan Baghumian (alanbach)]

This is no longer reproducible. I use this function all the time and it just works.
