Hi,
I am a total newb to Xen. I have run the commercial Xen Express
edition for about a day but I wanted to try running the new 3.0.4 rc2.
I have a Gentoo dom0, I have built xen from the latest testing source
archive, but none of my domU's will boot. I have tried several domU's
all with the same result; ttylinux, fedora, and gentoo. xm starts
creating the domU then dies while trying access the disk, it is a
loopback file disk.
Below is the output from the xend.log, udevmonitor, domU console, any
help would be appreciated.
