Subject: qemu_capabilities: Introduce virQEMUCapsGetDefaultMachine
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=cb01d2b5b11a21082e031b0c3000124ed47c88b7;p=people%2Fliuw%2Flibxenctrl-split%2Flibvirt.git

qemu_capabilities: Introduce virQEMUCapsGetDefaultMachine

Sometimes it may be useful to get a default machine for given qemu
binary. Fortunately, the default machine is stored always on the first
position in the supported machines array.
