Subject: qemu_driver.c: avoid double free on error path
X-Git-Tag: v0.7.5~77
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dd1604504144a37096d57a536b81f73dd1a9f898;p=thirdparty%2Flibvirt.git

qemu_driver.c: avoid double free on error path

* src/qemu/qemu_driver.c (qemudDomainMigrateFinish2): Set
"event" to NULL after qemuDomainEventQueue frees it, so a
subsequent free (after endjob label) upon qemuMonitorStartCPUs
failure does not cause a double free.
