This also occurs on XEN 2.07. After some digging, I found out what the problem 
was. The crash was a result of there not being enough dynamic IRQs for the 
VIFs.  To increase the number, increase the #define for NR_DYNIRQS in linux-
2.6.11-xen0/include/asm-xen/asm-i386/mach-xen/irq_vectors.h.  The default is 
128.  When Xen starts 5 are already used.  When a VM is started one goes to 
the backend block device. Although, dom0 should not die if the IRQs are not 
available, the VM should just fail to create with an appropriate error message.
