The feature was added to QEMU in 3.1.0 and it is currently blocking
c480ed
migration, which is expected to change in the future. Luckily 3.1.0 is
c480ed
new enough to give us migratability hints on each feature via
c480ed
query-cpu-model-expension, which means we don't need to use the
c480ed
"migratable" attribute on the CPU map XML.

The kernel calls this feature arch_capabilities and RHEL/CentOS 7.* use
c480ed
arch-facilities. Apparently some CPU test files were gathered with the
c480ed
RHEL version of QEMU. Let's update the test files to avoid possible
c480ed
confusion about the correct naming.
