For virt-p2v we want to get the host CPU model, topology etc, and the best way we found to do that was to pull it from libvirt capabilities[1]. Since libvirt is already parsing the host CPU information, and because /proc/cpuinfo is such a stupid format to parse, this is very convenient. Unfortunately it doesn't work unless libvirtd _and_ KVM are both installed. Without libvirtd installed:

...a private thread I'm posting this to libvirt-users. The specific question will be answered below. --- There are currently two interfaces which allow discovery of libvirts and in turn qemu's capabilities. Both return an XML which describes various aspects of the hosts or VMs capabilities. virConnectGetCapabilities(conn) https://libvirt.org/formatcaps.html The XML returned by this API describes mostly the host itself, the CPU, NUMA topology, security driver support, migration features but also describes guests architectures supported by the guest. In case of the qemu driver the guest section descr...

Hi all, I have been trying to find out cpu topology using libvirt. When I do 'virsh capabilites', I find this inside <topology> tag: <topology>       <cells num='1'>         <cell id='0'>           <memory unit='KiB'>3908488</memory>           <cpus num='4'>             <cpu id='0' socket_id='0'

Hi, Are there some kind of UUIDs for Host and Guest ? If yes , how may I retrieve them programmatically ? My goal is to trace GUEST migrations. Thx for help. Regards, J.P.

Did you really run these two examples on the same machine, with the same libvirt URI ? Both virsh and the python binding call the same libvirt API 'virConnectGetCapabilities' so will return the same data if run against the same libvirt. The socket_id, core_id and siblings data is a relatively new feature we added, so older libvirt won't show it.

libguestfs usually needs qemu. However it only requires an emulator for the same architecture, not for all architectures. libvirt-daemon-kvm pulls in qemu which pulls in emulators for all architectures, as well as a bunch of other stuff we don't need at all like network interface support and nwfilter. There are no Fedora TCG-only arches, so drop the conditional section. I also made support

This is tangentially related to: https://bugzilla.redhat.com/show_bug.cgi?id=1372668 The problem in that bug is that we didn't pass the source CPU model (Sandybridge in that case) through to the target RHV hypervisor. So when the Windows guest booted on the target it gives an error about CPU hardware being disconnected (although it otherwise boots and works fine). This patch series

v1 -> v2: - Support for passing topology through -o glance. - Support for passing topology through -o rhv. - Use bool for acpi/apic/pae struct fields in virt-p2v. - Write the xpath expression in error messages instead of file/line. - Fix more memory leaks in virt-p2v cpuid.c. - Passes make check & check-valgrind. There may be some other minor changes. I believe that everything
