There's a Redhat effort to make a dom0-able kernel. So far there's (has been?) a .20-series domU-kernel in unstable for i386. In fact, the situation is so grave that people are considering contingency plans. It could seem that Xen is dying slowly -- I'm not saying it is, but I'm saying it seems to be. For further such issues, the pkg-xen-devel list on alioth should be visited. > > - I see that my amd64-guest has only one CPU, but it is a multicore > > machine.

In that fashion, more than a single raw-steel processor will be used on the domU at a time. (Though if you have multiple domU's, there's a natural evening of workload, even though they each have only one CPU accessible.) > > - When I reboot my machine, the guests boot nicely.

It's probably related to the fact that Debian's Xen by default runs a `xm save` (IIRC) on the domains during shutdown to have the `xm restore`'ed on next bootup. -- But that only applies to clean shutdowns. > > - I have a time-problem.
