Sounds like a bug... The kvm binary should currently fall back to running without acceleration, if no acceleration is available. kirkl...@x200:/local/virt/iso$ sudo stop qemu-kvm [sudo] password for kirkland: qemu-kvm stop/waiting kirkl...@x200:/local/virt/iso$ time kvm -m 512 -cdrom lucid-desktop-amd64.iso open /dev/kvm: No such file or directory Could not initialize KVM, will disable KVM support I should think that vmbuilder should be able to continue using qemu (or kvm) in a non-accelerated manner. I just booted a LiveCD without KVM. It worked, though it took a long time to boot (~10 minutes). :-Dustin -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
