booting recent livecd images

[Colin Walters]

Hey,

Just wondering if anyone else was able to boot ISOs generated by
livecd-creator recently?  First off, when I try to use qemu-kvm, I get
random hangs during the bootup process (in different places; last message
might be SCSI or TCP congestion algorithm, etc).

So, I use "qemu".  The images I'm generating fail to find the root
filesystem (screenshot attached).

I'm building them on Fedora 7, git head livecd-tools.  This used to work, so
something regressed recently, and I have no idea what =)  How would one go
about debugging this?
