[libvirt] [PATCH 0/6] Fix guest CPU updates for inactive domains

[Jiri Denemark]

This series originally started as a cleanup work, but it turned out two
real bugs got fixed with this cleanup :-)

Since commit v2.2.0-199-g7ce711a30e libvirt stores an updated guest CPU
in domain's live definition and there's no need to update it every time
we want to format the definition. Thus libvirt should never internally
request a guest CPU update when formatting domain XML. But if it is
asked by a user to do so, it should use the same host CPU model which is
used when starting a domain to provide meaningful results.
