Subject: [PATCH] xencommons: Attempt to load blktap driver
Date: Tue, 15 May 2012 16:49:37 +0100 [thread overview]
Message-ID: <db614e92faf743e20b3f.1337096977@kodo2> (raw)
Older kernels, such as those found in Debian Squeeze:
* Have bugs in handling of AIO into foreign pages
* Have blktap modules, which will cause qemu not to use AIO, but
which are not loaded on boot.
Attempt to load blktap in xencommons, to make sure modern qemu's which
use AIO will work properly on those kernels.
