Subject: qemu: driver: Don't call qemuDomainDetermineDiskChain on block jobs
X-Git-Tag: v3.2.0-rc1~129
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ff9ed72bf1eb60cc4748f1e07d4ff18ba26ae69e;p=thirdparty%2Flibvirt.git

qemu: driver: Don't call qemuDomainDetermineDiskChain on block jobs

Our code calls it when starting or re-starting the domain or when
hotplugging the disk so there's nothing to be detected.
