RE: [Xen-users] Error: Device 0 (vif) could not be connected.Hotplugscripts not working.

the solution is to set loopback.nloopbacks=64 on the grub.conf
(module /vmlinuz-2.6.12.6-xen root=LABEL=/ ro maxcpus=1 console=tty1 
console=ttyS0,115200n8 loopback.nloopbacks=64)

I have 128 loop devices. And yes the domU partitions are filebacked.

kernel ="/boot/vmlinuz-2.6-xen"
memory = 3512
name = "chroom"
vif = [ '', 'bridge=xenbr0' ]
disk = 
['file:/xen/guests/chroom.img,sda1,w','file:/xen/swap/chroom.swap,sda2,w']
root = "/dev/sda1 ro"

If I do "ip route | grep veth" I have 8 veth so I need more. But how?

are your domU partitions file-backed?  if so, you have to increase the max 
number of loop devices (somewhere in /proc), or begin using LVM....
