Paolo, The full command line is: qemu-system-x86_64 -machine accel=kvm -m 1024m \ -net tap -net nic \ -drive file=/dev/zpool/testsrv,index=0,cache=writethrough \ -k en-us \ -no-kvm-irqchip \ -vga cirrus I've tried any combinations of "-net" options, but the result is always the same. I think this somehow related to http://article.gmane.org/gmane.comp.emulators.kvm.devel/109461, as setting "emulate_invalid_guest_state=0" solves the problem However, I'm not aware of any consequences of this change.
