[PATCH 3/3] qemu: save domain status after set domain's numa parameters

[Shanzhi Yu <shyu@xxxxxxxxxx>]

After set domain's numa parameters for running domain, save the change,
save the change into live xml is needed to survive restarting the libvirtd,
same story with bug 1146511; meanwihle add call
qemuDomainObjBeginJob/qemuDomainObjEndJob in qemuDomainSetNumaParameters
