[libvirt] [PATCH v5 2/4] qemu : Add loadparm to qemu command line string
Farhan Ali
alifm at linux.vnet.ibm.com
Thu Jun 1 16:36:25 UTC 2017
Introduce a new QEMU capability for loadparm and if the capability is
supported by QEMU then append the loadparm value to "-machine" string
of qemu command line.
Also add test cases for loadparm.
