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.
