Has anyone experienced this behavior? When I launch a domainU with Windows XP Pro as the guest OS, if I configure the domain to have more than on VCPU it starts up just fine.  Windows XP detects both CPUs… but after an average of 5 minutes, the domain0 machine actually seizes and needs a reboot.  If any other information is needed, let me know… but I’ve been able to isolate the issue to the use of vcpus > 1 in the configuration file for domainU.


Are there log files I can look at the will indicate what was happening on domain0 prior to the freeze?
