About IDE, it is working (at least with kernel 2.4.20). Someone has even compiled a linux kernel inside QEMU (slowdown factor of about 15), so vl begins to be usable for real tasks. There are still known problems if several processes use floating point at the same time.

Hi Fabrice, I haven't got the IDE emulation to work for me yet (is it supposed to yet?), but this allows the "-snapshot" option and "C-a s" to commit the disks. The blocks which change are committed to backing store, and a bitmap of changed blocks is kept. Diff + new test file below. Rusty.
