hello, "I didn't try to use a xen0 kernel to boot xenU before. I am not sure if it is okay. But I think you can try vmlinuz-2.6.16-1.2080_FC5xenU which comes from another Xen RPMs." thanks very much for the xenU - xen0 tip. a simple typo error costs so many problems... however, now when I run xm create fedora.fc4.xen.cfg -c the virtual machines boot freezes at: ... md: ... autorun DONE. kjournald starting.
