So what happened to the 'hvm' USE flag of the "xen-tools" package?

http://gentoobrowse.randomdan.homeip.net/package/app-emulation/xen-tools
says there is such a flag.  However:

So there is no such flag.  Apparently my installation is missing
'hvmloader', and I'm guessing that I would have that if I could enable
the 'hmv' USE flag.

How do I enable a USE flag that doesn't seem to exist?



You don't enable a USE flag that does not exist. How could you? It's not
there.

Have all hardware virtualization capabilities been removed from xen in Gentoo?
