Subject: [PATCH] qemu: Fix qemuDomainGetEmulatorPinInfo()
|
|
|
|
The order of pinning priority (at least for emulator thread) was
|
|
set by v1.2.15-rc1~58 (for cgroup code). But later, when
|
|
automatic placement was implemented into
|
|
qemuDomainGetEmulatorPinInfo(), the priority was not honored.
|
|
|
|
Now that we have this priority code in a separate function, we
|
|
can just call that and avoid this type of error.
|
|
|
|
