Hello All,

    I am trying to install FreeBSD 7.0 (8.0-current) as a guest OS
with RHEL 5.1/5.2. I compiled xen 3.2 with vmxassist=n as suggested in
bug 622. After I installed and booted this xen kernel I have difficulty
in starting the VMManager to create guest OS.

    Could anyone please provide details on which Linux OS & the
tools I may use to install FreeBSD as guest.

    I also tried with the instructions @
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/virtualization
-guest.html with kernel7.0-Release and kernel8.0-current. With both of
them I get a crash on doing xm create xmexample1.bsd -c. The trace is
below :

The problem is solved.

Keir Fraser have said in Xen-devel mailing list
that the problem should not exist in the current xen-unstable
(since yesterday).

I have just built xen-unstable and really there is no problem
with usage of /boot/loader in an HVM domain even on a Intel-based host.
So bug 622 does not exist anymore (at least for me).

Thank all and thank Keir again.
