libvirt users - May 2012 - Virtual Machines Stay Off If Rebooted

Hello, 


I am using libvirt on Ubuntu 10.04 Server and the following versions of these
packages:
libvirt-bin, libvirt0, python-libvirt - 0.7.5-5ubuntu27.22 
qemu-kvm 0.12.3+noroms-0ubuntu9.18 


Recently, when restarting a VM (either by issuing "sudo reboot" on a
Linux guest or choosing "Restart" from the Start Menu on a Windows
guest) the VM shuts down and remains off rather than simply restarting. I cannot
test "virsh restart <domain>" on this server as the version of
libvirt does not appear to support restarting - see
https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/368962


I do not receive any errors in /var/log when the shutdown occurs. Powering the
VM back on works, however I would prefer to have hot restart working so VMs that
are automatically rebooted to install updates will come back up automatically.
Do you have any suggestions on how to debug this behavior?


Thanks, 


Andrew

Hey Andrew,

Could you run the following?

#virsh dumpxml <domain>

The XML for one of my VMs contains some entries that look like the
following:

  <on_poweroff>destroy</on_poweroff>
  <on_reboot>restart</on_reboot>
  <on_crash>restart</on_crash>

What do yours look like?
