[libvirt] Patch for BUG ID 994657

Hi All, Here is the change I made to address the SIGSEGV we were seeing in libvirtd when attempting to create a new VM via virt-install: - We call virDomainDefFree after xenDaemonCreateXML returns to xenUnifiedDomainCreateXML. - xenUnifiedDomainCreateXML passes def to virGetDomain after XenDaemonCreateXML returns and before it calls virGetDomain. - xenUnifiedDomainCreateXML calls virDomainDefFree(def) when it's done with def, so no need to free inside xenUnifiedDomainCreateXML. ------------------------ patch ------------------------- --- /tmp/xend_internal.c 2013-08-07 12:03:03.000000000 -0600 +++ src/xen/xend_internal.c 2013-08-07 08:51:49.000000000 -0600 @@ -2171,7 +2171,9 @@ if (xenDaemonDomainResume(conn, def) < 0) goto error; - virDomainDefFree(def); + // We call this a little later and still want to use def, so + // don't free it just yet. + //virDomainDefFree(def); return 0;
