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.

Hi
I have a question about specifications of virsh start.
It is necessary to remove "type=ioemu" from the configuration file of Xen, when HVM domain installed Para Virtualized Driver use unmodified driver on Xen 3.0.3.
But,libvirt always adds "type=ioemu" to vif of HVM domain in xm_internal.c. Therefore virsh start cannot start correctly HVM domain installed Para Virtualized Driver.
Could you teach why does libvirt disregard setting of configuration file and set type=ioemu ?
This is surely a bug in libvirt, src/xm_internal.c, xenXMParseXMLVif:
if (hvm) { strcat(buf, ",type=ioemu"); }
