Agree. My current hardware is x86_64 capable, but my notebook isn't and
notebook has hardware virtualization support.

Hmm.

Yes, I need to upgrade to x86_64 (or reinstall) but no time now.
And I think with Fedora 11 it will update my kernel to 64-bit, what is
enough for my workstation. There are still lots of programs, which are not
64-bit and I don't need both i386 and x86_64 libraries on my system.
I know about limitations, but it's working well this way for me.

This was with current git version.

OK, this works too.

May be autodetection for java and kvm as default can be good for testers.
Now I still have to add these options:
  ./configure --with-qemu="qemu-kvm qemu" --with-java-home=no
