Yeah, it's either bug in qemu or libvirt should use another way of probing this stuff. > To fix this problem can be either way of the following: > 1. Specify the architectures in Libvirt as my patch. No way. This won't work if you want to start PPC domain on an x86 host or x86 domain on a PPC host. > 2. Specify the architectures in QEMU by modifying "qom-list-types" > command. Perhaps. We definitely need to find the right way of probing the data we care about. And it's likely both libvirt and qemu will need to be modified.
