[Xen-users] Network issue with xend


I am facing issues after upgrading one of the server from rhel5.5. (86_64) to latest rhel5.7  (86_64).   The server is under trunk configuraion.

I have set the network bridge as follows:


 vconfig set_name_type DEV_PLUS_VID_NO_PAD
dir=$(dirname " $0"

  /etc/xen/scripts/network-bridge  $@ vifnum=1 bridge=xenbr2  netdev=bond0.10
  /etc/xen/scripts/network-bridge  $@ vifnum=2 bridge=xenbr3  netdev=bond0.12
  /etc/xen/scripts/network-bridge  $@ vifnum=3 bridge=xenbr4  netdev=bond0.15
  /etc/xen/scripts/network-bridge  $@ vifnum=5 bridge=xenbr1  netdev=eth3

The server build on the eth3.  When the server is booted , after eth3 is up ,  server is pingable, until xend  starts.  As soon as xend is starting
the server is getting detached from the network. If I comment the last line  of the above entries, then there is no problem So something
is causing the issue with xend and eth3.

In the log file nothing is showing as an issue.  If I boot the server with 2.6.18-194.3.1.el5xen kernel
then xend is fine  and all the bridges are up. 

I have upgraded few lab server to rhel5.7 , there is no problem at all .

Any advice is appreciated.

Thanks in advance.
