Re: [libvirt] [PATCH v2 2/3] bhyve: implement ignore unknown MSRs feature

Implement the MSRs ignore unknown reads and writes feature that's specified using: <features> ... <msrs unknown='ignore'> ... </features> in the domain XML. In bhyve, it's just passing '-w' command line argument to the bhyve(8) executable.
