Glad to be of help. Two notes of caution, though:

1. I forgot to specify that memory allocation (VMSPLIT) *must* be 3G/1G (3G for userspace, 1G for kernelspace). If not, the VM would mysteriously refuse to start -- without any error messages.

2. I truly have no idea if my method works for 3.0. It's been tested thoroughlt with 2.6, though (to be precise: 2.6.38 and 2.6.39). I am still hesitant to use 3.0 because I saw people reporting bugs where a program is hard-coded to require kernel==2.6 (instead of requiring kernel>=2.6). IMO, it's not yet safe to tread the 3.0 waters. At least for another month. (As usual, YMMV)

That said, feel free to point out errors. And if you fail/succeed, please do tell me.

Happy paravirtualizing! :)
