No immediate plans. HVM Linux works as is (with non-PAE kernel). PV
Linux expects to have most of a 4G virtual address space available,
which, on a 32-bit host, is not immediately reconcilable with having
Windows use 2G for its kernel. I think being able to run small Linux
service VMs might be useful, and that could maybe be done by running
with 1.5G user space and .5G kernel space. On a 64-bit host, things
should be very much straightforward...
