After awhile it appears to lock up so I kill qemu.

Selecting "kvm" instead of qemu seems to help performance and the install actually finishes.

Software emulation is SLOW. Use KVM if you can.

Two obvious possibilities:
1 - do you have the right hardware for virtual support or are
you running pure software emulation?
2 - if you have the right hardware, it it enabled?

I have been running kvm on a proper machine, so I can't really tell you
how something else would run, but those are the prime reasons why qemu
and xen work poorly. You never have that problem with kvm, because it
won't try on a machine without the right hardware. Well, it will if you
tell it to be software-only qemu, but you get the idea.
