Subject: qemuDomainGetStorageSourceByDevstr: Lookup also '<dataStore>'
X-Git-Tag: v10.10.0-rc2~10
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=976300fdf4ebf0a00a4ea94fb60a34085ed1d45a;p=thirdparty%2Flibvirt.git

qemuDomainGetStorageSourceByDevstr: Lookup also '<dataStore>'

The <dataStore> volumes have their own 'id' so we need to be able to
look them up for the given image chain.
