Re: [Libvir] Question about specifications of virsh start
Thanks for answering.
Do you know what we can use to determine if the PV drivers are
installed
in a domain? I don't think there is anything extrinsic, so perhaps we
need to add something to the XML domain description.
I also do not know a method to distinguish whether PV drivers are installed
in a domain.
I think that there is only a method of changing XML to fix it,
if libvirt supports starting of a domain which installed PV drivers.
However, it is not a proper idea.
Thanks,
