Xend highly uses CPU with multiprocessor setup
...es.
After upgrade the system with Xen was slow - no iowaits only Steal time
was high. I tried workarounds regarding ACPI - only acpi=off was working
but the performance decrease was quite large due to only one CPU core
was active at that time.
The last workaround I am running right now is to set dom0_cpus to 1 in
xend-config.sxp. But this set dom0 cpus except the first one to paused
state and the dynamic configuration changes are not propagated to domUs
(e.g. memory [in/de]crease).
Can anybody tell me how to handle dom0_cpus correctly and what can be
the issue with multiprocessor setup of xend -...

x86/dom0: limit dom0_max_vcpus value
This caused particularly poor performance when booting a server in
uniprocessor mode for debugging reasons, and had 4 dom0 vcpus competing
for 1pcpus worth of time.
