Re: [libvirt] Fwd: Failed to get host power management capabilities
Quoting David Torres (d.torres(a)ct.co.cr):
Hi all,
My name is David Torres, I am from Costa Rica. See this is the problem I have with the
KVM instalation:
2012-10-03 20:28:17.395+0000: 25793: warning : qemuCapsInit:856 : Failed to get host
power management capabilities
2012-10-03 20:28:17.661+0000: 25793: error : virExecWithHook:328 : Cannot find
'pm-is-supported' in path: No such file or directory
This should be innocent, but
And this error from the kern.log:
Oct 4 21:50:53 kvm kernel: [22727.849902] device vnet0 entered promiscuous mode

And when I try to create a Virtual Machine from the Virtual Machine Monitor, I got this
error message:

This is your problem - /dev/kvm is a directory. You should be able to (as root):
mv /dev/kvm /dev/kvm.bak
mknod /dev/kvm c 10 232
chmod 666 /dev/kvm
Note that chmod 666 isn't ideal, but since I don't know the state of the
rest of your install, it should at least work.
It would be interesting to see what is in that directory, i.e. the result
of
ls -l /dev/kvm /dev/kvm.bak
ls -ld /dev/kvm /dev/kvm.bak
