When running under Xen you need to use "xm info" and check the caps if you can run HVM (hardware virtualized) or not. Dom0 Linux kernel won't see the cpu flags in /proc/cpuinfo since dom0 is a VM, and the hypervisor is hiding the flags from VMs. (at least until Xen Nested Hw Virt is merged, which should be soon). Other option is to read "xm dmesg" for supported features: http://wiki.xen.org/xenwiki/XenCommonProblems#head-39c253c76df6f0fa4fb7ff4769cc733284bac9cb -- Pasi -- xen mailing list xen@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/xen
