Hi, I have read that unmodified guests, like Windows can run only if the CPU supports virtualization. The computer has two dual core Opteron 880 CPUs. Debian Etch is installed on domU. How can I get know whether this CPU is supported? The description of a CPU core from /proc/cpuinfo: processor : 3 vendor_id : AuthenticAMD cpu family : 15 model : 33 model name : Dual Core AMD Opteron(tm) Processor 880 stepping : 2 cpu MHz : 2389.460 cache size : 1024 KB physical id : 3 siblings : 1 core id : 0 cpu cores : 1 fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu de tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxextfxsr_opt lm 3dnowext 3dnow pni lahf_lm cmp_legacy bogomips : 5975.48 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp Thanks, Miklos _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

All 3rd Gen Opterons have 4-digit model numbers. 3-digit model numbers are 2nd and 1st Gen Opterons. They do not support SVM, which means they cannot run hardware-assisted VMs (HVM) and thus, can''t run Windows.> The description of a CPU core from /proc/cpuinfo:> processor : 3 > vendor_id : AuthenticAMD > cpu family : 15 > model : 33 > model name : Dual Core AMD Opteron(tm) Processor 880 > stepping : 2 > cpu MHz : 2389.460 > cache size : 1024 KB > physical id : 3 > siblings : 1 > core id : 0 > cpu cores : 1 > fpu : yes > fpu_exception : yes > cpuid level : 1 > wp : yes > flags : fpu de tsc msr pae mce cx8 apic mtrr mca cmov pat > pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxextfxsr_opt lm > 3dnowext 3dnow pni lahf_lm cmp_legacyNote how there is no mention of "svm" or "vmx" in the flags line. This means there is no support for hardware-assisted VMs. -- Freddie fjwcash@gmail.com _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
