Logic bug. This fails with "Refusing to undefine" if the unlink()
succeeds. Rather, you want:
I changed this before posting, but sent the old patch without the change
mistakenly. :(
if (virFileExists(name)) {
if (flags& VIR_DOMAIN_UNDEFINE_MANAGED_STATE) {
if (unlink(name)< 0) {
virReportSystemError(errno, "%s",
_("Failed to remove managed state for domain"));

qemuReportError(VIR_ERR_OPERATION_INVALID, "%s",

}
}
Needs a v3.
