[Xen-devel] [PATCH] bvt scheduler setup based on other or shadow domain
Hi.
The bvt schedule setting error which I found in the past in xen 2.0
series is not modified at xen 3.0 (-unstable).
When I found it, there are two solutions, so I can not decided which
more better.
In xen 3.0, new scheduler (EDF) is improved this problem.
Therefore, this patch is modified above problem similar to new
scheduler.
In xen 3.0, new scheduler is default scheduler, but I happy that this
patch is applied.
