I have just attempted to boot domU with 2.6.7 (dom0 still 2.4.26), and I get this: <snip> Initializing Cryptographic API Initialising Xen virtual block device Using anticipatory io scheduler Xen virtual console successfully installed as tty Event-channel device installed.

However, I''m really struggling to reproduce it. What cset is at the head of your tree? I''d be grateful if you could try undoing the bk repository so that you remove cset 1.1218, and then try all the way back to before 1.1206.> also, on boot I get bogomips readings from 900 to 100. Is there any problem with this?Is this on 2.4 or 2.6, which domain? I thought this was fixed a week or so ago. Hmm, I''ve just spotted that there is a blk device issue running a 2.6.7-xen0 (as opposed to 2.6.7-xenU) kernel in domains >0. I don''t think it''s your problem though, as the device completely fails to register. I''m afraid I''m going away for the weekend, so this will have to wait until Sunday evening...

that was it. it seems to work fine now (except that I forgot to copy the modules in - how does everyone else update the modules in the xenU domains when they update the kernel?
