Had to update/merge in recent caps changes... Also had the same wierd
problem in domain_conf.c and qemu_command.c w/r/t 'git am -3' merging
code into wrong place...
ACK - will push shortly (this was done before freeze, but I only got to
it today...Prior version only needed minor updates... The default
setting is to not enable feature, so should be safe.)
Tks -
John
