Subject: [PATCH] qemu: check backing chains even when cgroup is omitted
|
|
|
|
https://bugzilla.redhat.com/show_bug.cgi?id=896685 points out
|
|
a regression caused by commit 38c4a9c - libvirt only labels
|
|
the backing chain if the backing chain cache is populated, but
|
|
the code to populate the cache was only conditionally performed
|
|
if cgroup labeling was necessary.
|
|
|
|
* src/qemu/qemu_cgroup.c (qemuSetupCgroup): Hoist cache setup...
|
|
* src/qemu/qemu_process.c (qemuProcessStart): ...earlier into
|
|
caller, where it is now unconditional.
