The pconfig feature was enabled in QEMU by accident in 3.1.0. All other newer versions do not support it and it was removed from the Icelake-Server CPU model in QEMU. We don't normally change our CPU models even when QEMU does so to avoid breaking migrations between different versions of libvirt. But we can safely do so in this specific case. QEMU never supported enabling pconfig so any domain which was able to start has pconfig disabled. With a small compatibility hack which explicitly disables pconfig when CPU model equals Icelake-Server in migratable domain definition, only one migration scenario stays broken (and there's nothing we can do about it): from any host to a host with libvirt < 5.10.0 and QEMU > 3.1.0. https://bugzilla.redhat.com/show_bug.cgi?id=1749672Signed-off-by: NJiri Denemark <jdenemar@redhat.com> Reviewed-by: NDaniel P.

The family/model numbers are nice for humans or for comparing with /proc/cpuinfo, but sometimes there's a need to see the CPUID representation of the signature. Let's add it into a comment for each signature in out cpu_map XMLs as the conversion is not exactly straightforward.

The feature was added to QEMU in 3.1.0 and it is currently blocking migration, which is expected to change in the future. Luckily 3.1.0 is new enough to give us migratability hints on each feature via query-cpu-model-expension, which means we don't need to use the "migratable" attribute on the CPU map XML. The kernel calls this feature arch_capabilities and RHEL/CentOS 7.* use arch-facilities. Apparently some CPU test files were gathered with the RHEL version of QEMU. Let's update the test files to avoid possible confusion about the correct naming. Signed-off-by: NJiri Denemark <jdenemar@redhat.com> Reviewed-by: NJán Tomko <jtomko@redhat.com>
