Richie is right. PV Kernel uses xvda.

Try with :

disk = ['file:/xen/domains/dom1/diskimage.img,xvda1,w','file:/xen/domains/dom1/swapimage.img,xvda5,w']

And you have to modify the "root" entry :

root = "/dev/xvde1 ro" -->  root = "/dev/xvda1 ro"

Did you modify the /etc/inittab file inside your domU to get a getty on hvc0 ?

PV uses xvda.

It doesnt make sense. This is the path of the "disk" that is mapped to sda on dom0 FS. I have created this "diskimage.img" and formatted int ext3 to be the disk of my VM. Besides, there is no xvda in my /dev inside domU

INIT: Entering runlevel: 4
Starting enhanced syslogd: rsyslogd.
Starting periodic command scheduler: crond.

My guess is that it is starting gdm at this point.  I would either try booting single user mode or mount the domU fs in dom0 and remove the /etc/init/gdm.conf (or rcX.d links) file.
