Another feature enhacement requirement:
can you add an option "--kvm" to use qemu-kvm instead of qemu? It's much faster (aprox 50%) on machines, which support hardware virtualization. Also you need to remove --no-kqemu option, which is not recognized by qemu-kvm. May be ability to run kvm may be autodetected in future, but I think, if there is no kvm support, qemu-kvm will run in normal qemu mode.
Yes, this needs to be sorted out. It should also be possible to choose which qemu/kvm/etc binary to run.
I also discovered that the -no-kqemu switch doesn't exist at all on PPC, which is one of the reasons that it fails to run on that platform. There's another problem with PPC as well, qemu on PPC doesn't seem to support the -initrd option. As usual, since I don't have a PPC machine it's hard to debug this. Instead I hacked around it:
