Hi,

> I answer to this mail because it's related to the discussion in this =
thread. As told I have my Debian Dom0s and now I wan't to create a =
FreeBSD Xen PV DomU. Does I really need a HVM guest like described here: =
http://wiki.sysconfig.org.uk/display/howto/Xen+FreeBSD+8.2+DomU+%28PV%29+-=
-+Step+by+Step+Howto

As that is my blog/wiki and I wrote that article: No, you don't need to. =
Just carry on with "Create a PV guest - Fast Track" (further down in =
that article).
It describes how to create an image from any other FreeBSD installation.=20=


That tutorial is a guide to quickly walk you through the steps and =
differences. It's probably not complete and certainly not the only way.


However, if you intend to run 64bit, you are restricted to HVM (use the =
XENHVM kernel to get better performance from the optimised device =
drivers for HVM).=20
If you are planning on running 32bit, you can use PV.
I think that is still valid for 9.0. And mind you, PV is (or was?) also =
limited to about 850M memory in the DomU.=20


> I already downloaded the prepared DomU Image but it's version 8.2 and =
not 8.3 or 9.0 so could I simply upgrade the guest to 8.3 for example?

The image which I put together there? It's not up to date. You can =
update it, but make sure to compile the kernel appropriately. The =
Generic kernel will not offer any PV or HVM support.
Give it a go. The beauty of virtualisation is that you can quickly roll =
back if you break it :) =20


Cheers
C.
