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.

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

We thought the ''ping error'' problem seemed non trivial.

Hi,
This is just to report that the problem of ''brctl'' is fixed by
installing
the latest bridge-utils rpm : bridge-utils-1.2-5.ppc64.rpm .
With the latest bridge-utils installed, I
. used the original /etc/xen/scripts/xen-network-common.sh
. changed the vif line in the domU configuration file to "vif = [
'''' ]"
domU is booted properly with dhcp working. the ''brctl show'',
''brctl
showmacs xenbr1'' kind of commands give similar output as the reference
machine (Dans js20 running sles 10).
However, the ping-out still gives ''no buffer space available''
after exact
12 successfuly echo-replies.
Details:
. On dan''s machine, the bridge-utils version, based rpm -qa, is
bridge-utils-1.0.6-14.1 . I could not find the exact package through
rpmfind. I used the latest version . Here is the binary package : (See
attached file: bridge-utils-1.2-5.ppc64.rpm)
. David, today, on blade cso83, GPFS directory is mounting during booting.
Dilma looked at it. Now we need to (1) kill the runmmfs process first, and
then (2) run mmstartup to mount /gpfs1xen . This maybe due to your change
to the cso script as you mentioned ?
Regards,
Hao
