One question, though...
In Xen2 I've sometimes done the CPU allocation manually becaue the
Xen2 scheduler has seemed, well, less than perfect for my
applications. It is then very useful to be able to examine the result
in the "CPU" column in the output from "xm list". Where do I find
information about which domU was allocated to which CPU in Xen3? That
information seems to be missing from both "xm list" and "xm top".
The xen3 scheduler is dynamic, and can move a domain from one CPU
depending on the load of each CPUs (which Xen2 couldn't do), so
maybe the issue
you had with Xen2 won't show up here. But if you really need to you
tell Xen on which Cpus a domU is allowed to run, e.g.:
cpus = '2-5'
(this is on a 8-way server; this domU is allowed to run on CPUs 2
to 5 and
won't have access to cpus 0, 1, 7 or 8).

Many thanks to both of you. All working nicely and no further
questions. (For the moment.)
