Ah well. That was my only hunch :) > Are you saying that qemu should not be expected to work on a non-HV-enabled > system? Qemu should work on any system. What will vary is whether it will use the hardware-supported VT method of virtualisation, which gives you near-native speeds. If that is not available, Qemu can fall back to pure-software CPU emulation (indeed, that was originally the only thing it did. Then kqemu came out, which provided kernel-accelerated emulation; then qemu was partially forked by the KVM people to support using /dev/kvm; then Qemu grew it's own VTG support which afaik uses /dev/kvm as well.) My hunch was the problems were due to the software stack falling back to pure software emulation. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
