Re: [Xen-users] network troubles...

[The Smoking Man <datashark@xxxxxxxxx>]

hi all. 

In the end it was all resumed to a PATH problem in ... 
/etc/xen/scripts/vif-bridge. It happens that brctl and ifconfig are
sillenly dying with xen original config due to not being in the
expected PATH.
replacing (in  /etc/xen/scripts/vif-bridge) brctl by /sbin/brctl
and ifconfig by /sbin/ifconfig solved everything. I have now xen
running smoothly and stably and a dual opteron (tyan 2882) with 10GB of
RAM.  

Best regards.

hi have you had any joy in getting your networking running between dom0 and U. I am having the same problem but have been unsuccessful in finding any doco or answers.

Hi all,

I've installed latest xen (3.0)  on a clean box under gentoo (32bits). Dom 0 boots fine. DomUs also. trouble is that i cannot get networking to work between Dom)/DomU in any way :(  (there are no afaik abnormal stuff in xen log btw)

i also updated  /etc/xen/scripts/network-bridge to work under gentoo as stated i de -devel ML.

bellow are my configs.

Any help hint would be greatly appreciated.
