[libvirt] [PATCH 2/4] Add a <graphics> type for SPICE protocol

[Dan Kenigsberg]

Thanks for the patches (and sorry for the late response).

The patches are fine, though I am still missing a means to control which
of spice channels are to be encrypted. Also missing is a way to set
key/cert files and cipher suite per domain. (I aksed spice folks to
avoid this problem by using reasonable defaults). More of a problem is
the need to set/reset spice "ticket" (one time password), or at least
disable it completely on the command line (with ,disable-ticketing).

this hides spice's own default, and sends ",ram=0" if xml lacks vram
attribute. I think it would be better to drop ",ram" completely if
vram==0.
