Tell us why you don't want a paravirtual VM. If you tried xen 4.0.1, you must 
have tried a pv VM. What goes wrong with that?

To convert the VM to paravirtual, use the kernel-xen in C5.5

You need at least 2 new modules in your initrd.img: xennet and xenblk

/sbin/mkinitrd --with=xennet --with=xenblk --without-dmraid -v -f 
/boot/initrd-$(uname -r).img $(uname -r)

If the above is awkward, before you install kernel-xen (xen aware kernel), make 
the following edit

#cat >> /etc/sysconfig/mkinitrd/pvxen<<EOL

#chmod +x /etc/sysconfig/mkinitrd/pvxen

#yum install kernel-xen

then in your VM.cfg use bootloader=pygrub or copy the vmlinuz-xx.yy-el5xen and 
initrd-xx.yy-el5xen.img to dom0

This may not fix the crash, but performance should improve.
