It might give us a clue as to whether the problem is with the backend blk driver or within the domain itself (the 2.6.7 implementation is completely different).I can certainly give the 2.6.7 guest another try. I did have it booting, but I didn't persist with it long enough to tell if there was fs corruption -- there seemed to be issues loading modules, and when I compiled everything in, I got a gpf when racoon tried to use a PF_KEY socket. I'll try and get some useful dumps for both these problems.I haven't tried loading modules, but I can't think why it wouldn't work (assuming the mechanism is basically the same as 2.4). It's different enough to need new userspace tools. The symptoms of failure are a GPF, and the userspace process stuck in D (be it insmod or lsmod). The results of feeding the GPF to ksymoops are below (I hesitate to say it's actually decoded). BTW: what's racoon, and what's a PF_KEY socket? racoon is the ISAKMP daemon used with the 2.6 kernel's KAME IPSec code. It uses a PF_KEY socket to communicate with the kernel. I've successfully used it in a 2.4 guest. Chris.
