Subject: virQEMUCapsReset: also clear out hostCPUModel
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=1157678f81182f8fb1b88c6e61593f087becbc27;p=libvirt.git

virQEMUCapsReset: also clear out hostCPUModel

After succesfully reading an outdated caps cache from disk,
calling virQEMUCapsReset did not properly clear out the calculated
host CPU model. This lead to a memory leak when the host CPU model
pointer was overwritten later in virQEMUCapsNewForBinaryInternal.

Introduced by commit 68c70118.
