CentOS virt - Aug 2009 - OpenBSD 4.5 in HVM domU network timeouts

Hi all,

I am trying to install openbsd 4.5 amd64 in HVM domU.
dom0 runs CentOS 5.3 x86_64 with xen 3.4.0

During installation process everything is looks good except network..
When I've configured the network parameters I began to receive
multiple messages like this -

re0: watchdog timeout

and ping from dom0 to that domU is looks awesome:

$ ping 10.10.10.10
PING 10.10.10.10 (10.10.10.10) 56(84) bytes of data.

rtt min/avg/max/mdev = 1831.964/3849.323/7833.997/1421.748 ms, pipe 8

Does anybody know what's the problem? Is there any workaround?
I've googled for something about "model=ne2k_pci" options in xen
domain config, but haven't tried it yet (installation still in the
progress..). Any hints?

Thanks
