[libvirt] [PATCH 0/5] qemu: Detect KVM usability correctly

[Andrea Bolognani]

There are a few cases in which we're not reporting the correct
information through 'virsh capabilities', leading to applications
such as libguestfs attempting to launch KVM guests on a host that
doesn't actually support them.

Our code is also more complicated than it needs to be due to
backwards compatibilty reasons that we no longer care about these
days, so we can perform some cleanup there; there are further
cleanup opportunities in the same area, but some of them are a
bit tricky so I'll leave them for a follow-up series.

We also get some extra test coverage pretty much for free. Yay!

Andrea Bolognani (5):
  tests: Reuse qemucapabilities data for qemucaps2xml
  tests: Add more tests to qemucaps2xml
  qemu: Drop QEMU_CAPS_ENABLE_KVM
  qemu: Clarify QEMU_CAPS_KVM
  qemu: Don't check for /dev/kvm presence
