Re: [libvirt] [PATCH v3 04/20] Remove probing of machine types when canonicalizing XML

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; When XML for a new guest is received, the machine type is immediately canonicalized into the version specific name. This involves probing QEMU for supported machine types. Replace this probing with a lookup of the machine types in the (hopefully cached) qemuCapsPtr object Signed-off-by: Daniel P.
