Re: [Xen-devel] [PATCH]: libxc: set all VCPU's online by default in HVM info table

[George Dunlap <George.Dunlap@xxxxxxxxxxxxx>]

This patch seems to have been acked, but never actually applied.  It's
probably still worth applying at least to -unstable.  I'd consider
backporting it to 4.1 as well...
