[libvirt-users] Host does not support virtualization type 'xen'

Thu Mar 15 16:06:54 UTC 2012

Alex,

I built Xen from source but I didn't change any default options. I
configure the libvirt as you showed me and it output the same result.
However, the issue is still there. Do you think there are other ways to get
it around?

Thanks,
