Hi Avi, The command line is created using libvirt 0.7.5 (compiled by me) and looks like this: /usr/bin/kvm -S -M pc-0.11 -enable-kvm -m 512 -smp 1 -name winxp -uuid f99c79b6-2706-dff0-af5c-cea53559f89c -chardev socket,id=monitor,path=/usr/local/var/lib/libvirt/qemu/winxp.monitor,server,nowait -monitor chardev:monitor -boot c -drive file=/home/images/winxp.raw,if=ide,index=0,boot=on -net nic,macaddr=52:54:00:c4:90:94,vlan=0,model=rtl8139,name=rtl8139.0 -net tap,fd=41,vlan=0,name=tap.0 -serial none -parallel none -usb -vnc :5 -vga cirrus While the host /proc/cpuinfo contents look like this: demo-laptop:/home/images# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 23 model name : Intel(R) Core(TM)2 Duo CPU T6670 @ 2.20GHz stepping : 10 cpu MHz : 1200.000 cache size : 2048 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 xsave lahf_lm ida tpr_shadow vnmi flexpriority bogomips : 4388.31 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: I may also be able to arrange for remote SSH access into the box - mail me off-list if you are interested.
