Hi, 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: #!/bin/bash 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. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
