Same thing here. This happens when OS-type is windows, kernel/hardware acceleration is enabled, and I press 'next' in the dialog where I have to choose where to install the virtualized system.

This also affects virt-install.

Here's a patch which should correct this problem. The dicts which contained the settings for everything except Linux were missing the virtio_blk and virtio_net keys. It would also be possible to change the behavior of the get_virtio_{net|blk} functions to return the default if the ostype didn't have the key, but assuming the os_type has all the options seems to be more inline with the rest of the program.

After this I was able to create and start windows-winxp and unix-freebsd6 variants.
