Subject: qemu: Use correct variable in qemuDomainSetBlockIoTune
X-Git-Tag: v3.4.0-rc1~19
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0d3aff58e7ed190c97b40ee92f58cb0180cef6fe;p=thirdparty%2Flibvirt.git

qemu: Use correct variable in qemuDomainSetBlockIoTune

'param' contains the correct element from 'params'.

If the group name would not be the first parameter libvirtd would crash.

Introduced in c53bd25b13.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1455510
