X-Git-Tag: v0.8.6~50
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=388fa6257e2ea610c6c541e6d1b667c80fd40657;p=thirdparty%2Flibvirt.git

qemu: setvcpus: Save config changes to disk

Currently changes to the persistent config aren't flushed to disk, meaning
they are lost if the domain is redefined or libvirtd is restarted.
