Maybe Kip Macy can supply a change list of what he had to do for FreeBSD. Things may be slightly easier now the "writeable pagetable" interface is available (the Linux 2.6 port uses this).> Ditto for Xen running in 64 bit mode.x86_64 port is still work in progress.> Will Xen64 support 32-bit operating systems?Doesn''t seem much point running 32 bit paravirtualized guests (it will still run 32 bit user space), and it makes life easier not to. However, there are plans to run 32 and 64 bit unmodified guests on a 64 bit hypervisor (as well as 64bit paravirtualized guests) using Intel VT extensions.

Whether VT Xen will run under VT Xen (allowing arbitrary recursive virtualisation) will depend on whether VT itself supports this recursion. -- Keir ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

It has already been posted.
