[libvirt] [PATCH 3/4] Allow multiple parameters for schedinfo



virsh schedinfo was able to set only one parameter at a time (not
counting the deprecated options), but it is useful to set more at
once, so this patch adds the possibility to do stuff like this:

virsh schedinfo <domain> cpu_shares=0 vcpu_period=0 vcpu_quota=0 \
emulator_period=0 emulator_quota=0
