this is less than ideal. The atom cpu, even though 2 core, has hyper
threading which makes dom0 think it has 4 cpus so you have to do some
testing to figure out which cpu's are actually on a separate core.
dom0 by default has access to all cores. I only have 2 domU's. One has:
I'm not sure if my system has hyperthreading or not - I guess I'm going
to have to figure that out first.

Do you know if there's a way to pin dom0 to a specific core - I think
I'm seeing kernel panics caused by dom0 (SMP errors that show up every
once in a while). I'm running a high-availability configuration running
Xen over DRBD over software RAID10 - and I expect panics occur when all
the bits line up just right before swapping into/out of dom0 - but I
don't have the instrumentation to drill down that far.
I would also go with debian squeeze unless you are having trouble with
the debian installer. I normally use the net install disk
http://www.debian.org/distrib/netinst and then use aptitude to install
the rest of my packages. I don't ever use the preset tasks to install
any thing.
I think I might just try going to Squeeze. As I read the bug reports,
the ones that seem to reference the kernal panics I'm seeing are shown
as closed in Squeeze.

Are you running Xen 3 or 4?



Running 3.2. You can pin with the cpu settings (dom0-cpus) in xend-config.sxp
