Thanks a lot, this is great news.

Just out of curiosity:  Are there any reasons why you want the xensource 
kernel when the debian kernel works OK?

Super!  How about using the debian lenny 2.6.26 domU kernel [1] on top 
of the debian etch 2.6.18 dom0 kernel [2] (with Xen 3.3)?  I guess that 
would work?
And my last silly question: Are there any real benefits on using a 64 
bit dom0 [3] when I am only serving 32 bit debian domU's?
(I'm sorry for my detailed questions -- I am setting up a xen server 
tomorrow and merging a stand-alone server to it, and my setup time is 
severely limited.)
Best regards,
Henrik
