kernel = "/boot/vmlinuz-2.6.28-rc8-tip"
ramdisk = "/boot/initrd.img-2.6.28-rc8-tip"
memory = "256"
name = "ubuntu-hardy-jailtime"
disk = ['tap:aio:/home/deshantm/ubuntu.8-04.64.img,sda1,w']
root = "/dev/sda1 ro"
extra = "xencons=tty"

I also tried file:/ for the disk

Same errors.

I poke around a little more in the xen logs to see if I can find any more
useful info on the guest problem

I put the dom0_mem down to 512M for now, that should do.

I think that mem=3G is still necessary. I'll send some vtd logs that show it
crash without mem=3G and not crash with mem=3G

I fixed the lsscsi problem previously (earlier testing).
udev is installed. There may be some issue with its working with
the dom0 kernel though. I have seen the error messages
of /sbin/scsi_id: not found

I just pulled the latest patches. The vga is closer to working. I don't see
the kernel boot messages, but I do get a login prompt (text only).
Which works.

My Xorg logs (a working one and a non working one) are attached.
