Hi, I understand that with Xen 3.4 viridian=1 can be specified in the configugration file to enable viridian support, one of the effects of which is to set a cpuid bit to enable relaxed timers, I was wondering if the same bit could be set using the cpuid= setting on older versions of Xen? I run Xen 3.2.1 and find that under heavy load my Windows 2008 and Vista VM's will BSOD with CLOCK_WATCHDOG_TIMEOUT (101), this is pretty inconvenient on its own but if the VM has a pci passthrough device the entire system will lock up when this happens, the same lockup happens if I destroy a VM which has a passthrough device. I have tried running Xen unstable but when I install gplpv drivers my windows vm's BSOD with a 7E, I really need the performance boost of gplpv drivers or I would simply run unstable with no pv drivers.
