Is there a limit on the number of VIF devices in a domU?  When I added a
fourth one, ifconfig reports:
  eth3: error fetching interface information: Device not found

My domain config reads (in part):
  ip     = "192.168.2.2"
  netmask = "255.255.255.0"
  gateway = "192.168.2.1"
  vif = [ 
   'bridge=xenbr2, ip=192.168.2.2', 
   'bridge=xenbr3, ip=192.168.3.1', 
   'bridge=xenbr4, ip=192.168.4.1', 
   'bridge=xenbr5, ip=192.168.5.1'
  ]

It looks like xend is not creating the fourth interface because 
xm list --long reports only three (it report, in part):
 ....
        (linux
            (kernel /boot/vmlinuz-2.6.12.6-xen)
            (ip
192.168.2.2:1.2.3.4:192.168.2.1:255.255.255.0:inner:eth0:off)
            (root '/dev/sda1 ro')
            (args 2)
        )
    )
    (device
        (vif
            (backend 0)
            (script vif-custom)
            (ip (192.168.2.2))
            (bridge xenbr2)
            (mac 00:16:3e:7d:63:9d)
        )
    )
    (device
        (vif
            (backend 0)
            (script vif-custom)
            (ip (192.168.3.1))
            (bridge xenbr3)
            (mac 00:16:3e:7c:de:10)
        )
    )
    (device
        (vif
            (backend 0)
            (script vif-custom)
            (ip (192.168.4.1))
            (bridge xenbr4)
            (mac 00:16:3e:1b:c1:66)
        )
    )
    (device
        (vbd  ...

 Hoping that someone can point me to a config parameter to fix this ...
