[libvirt PATCH 0/6] qemu: Invalidate capabilities when host CPU changes

[Jiri Denemark]

The host CPU related info stored in the capabilities cache is no longer
valid after the host CPU changes. This is not a frequent situation in
real world, but it can easily happen in nested scenarios when a disk
image is started with various CPUs.

Jiri Denemark (6):
  util: Define g_autoptr callback for FILE
  hostcpu: Introduce virHostCPUGetSignature
  hostcpu: Implement virHostCPUGetSignature for x86
  hostcpu: Implement virHostCPUGetSignature for ppc64
  hostcpu: Implement virHostCPUGetSignature for s390
