Subject: qemu: process: Clean automatic NUMA/cpu pinning information on shutdown
X-Git-Tag: v3.3.0-rc1~31
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1730cdc665a499afc28683a4ce21493f967411b7;p=thirdparty%2Flibvirt.git

qemu: process: Clean automatic NUMA/cpu pinning information on shutdown

Clean the stale data after shutting down the VM. Otherwise the data
would be leaked on next VM start. This happens due to the fact that the
private data object is not freed on destroy of the VM.
