I mean, something like having the 1 pCPU only pool when you run your domU *not* including pCPU #0? I can't point the finger to anything specific right now, but, you now, pCPU #0 is the first being brought up, etc. Probably, as scheduling does not matter much to you, you can even just use vCPU affinities/pinning, like having Dom0 pinned to pCPUs 0-2, and your DomU to pCPU 3. =20 > > It's a busy period, with the 4.4 release, etc., but, as repeatedly > > said,=20 > > I'm up for helping with this, if help is needed! :-P > Thanks.
