Indeed, I tweaked one BIOS setting, I disabled hyperthreading. The R410 BIOS has a CPU menu with (among other options): - Logical Processor: this is 'HT', default is enabled, I have disabled it. - Virtualization Technology: default is disabled. Kept disabled. - Number of Cores per Processor: default is 'All'. Options are single/dual/all. Kept 'all' defalut. I just tried to boot Xen 4.0 hypervisor after reverting to the factory default 'HT enabled' (aka Logical Processor: Yes), same bug. Then I swithed off HT again, and enabled 'Virtualization Technology' (setting which I totally overlooked, but why is it disabled as default ?).
