Public bug reported:
Binary package hint: kvm
Using the KVM84 backport for hardy and the libvirt backport, it seems
that VMs regularly just "lose" their CPU. Can't provide much more infos
sadly, as the VM just stops writing to log files as soon as this
What I can provide though is a munin graph of when it happens:
The downtime at 2 in the morning was a reboot of the host (therefore
normal). At 6 o'clock though you can see the IRQs dropping and the CPU
just "disappearing" from the graph. The other thing I don't understand
is how munin continued working...
Rebooting the VM solves the issue.
