PLEASE, post these to the mailing list, it is important that the community
sees these issues.
I'm happy you have some networking, I have some more network stability
fixes that I'll be pushing shortly.

domU network problem , 10/30
progress(Document link: Jimi
Xenidis)
Hi Jimi,
Dan, Jiuxing and I worked together on the problem. First we have following
summaries
1. the problem is now 'domU network not working properly' :
ping-to-outside runs into error after 30 seconds ; domU hangs in nc/netcat
test when receiving long stream (MB or so). For the pint-to-outside issue,
when domU runs into error, outside can still ping to the domU.
cso238:/ # ping 9.2.78.83

2. brctl does not work properly on our environment. 'strace brctl show'
indicates 'ioctl(3, SIOCGIFBR, 0xffc381d4) = -1 EINVAL (Invalid
argument)' . And on SLES 10 environment, brctl show works fine.
In addition, how the dhcp problem is gone ? Bulent reconfiged the dhcp
server to have more show-live IP available . Now, domU can get IP
cso238:/ # ifconfig
eth0 Link encap:Ethernet HWaddr 00:16:3E:F9:BB:B3

TX packets:20 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:1256 (1.2 Kb) TX bytes:1256 (1.2 Kb)
We thought the 'ping error' problem seemed non trivial.
