[Xen-users] Xend hangs on starting time!

[pengfei zhang <zpfalpc23@xxxxxxxxxxx>]

I come across some problem when using xen-4.1.1-rc1-pre from xen-4.1-testing
tree and 2.6.32.36xen linux kernel from
git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git.
when I use 'xend restart' , it hangs when kernel dmesg printing 'Bridge
firewalling registered' and the console show below messages:

localhost# xend restart
Nothing to flush.
Cannot get current device settings: Operation not supported
  not setting speed
  not setting autoneg

I check the /var/log/xen/xend.log:

1655 [2011-04-26 10:17:16 4260] INFO (SrvDaemon:332) Xend Daemon started
1656 [2011-04-26 10:17:16 4260] INFO (SrvDaemon:336) Xend changeset: Thu Apr

check the /var/log/messages:

after I kill the hanging xend start process using keyboard, the console show
the messages:
localhost# xend restart
Nothing to flush.
Cannot get current device settings: Operation not supported
  not setting speed
  not setting autoneg
^CTraceback (most recent call last):
