[CentOS-virt] Xen not applying custom network script on startup
I'm seeing an issue with xend not running a custom network script automatically, but works when I run it manually. In /etc/xen/xend-config.sxp I've changed: (network-script network-bridge) TO: (network-script network-custom) Here is /etc/xen/scripts/network-custom: # !/bin/bash # network-custom script=/etc/xen/scripts/network-bridge case $1 in start) $script start vifnum=0 bridge=xenbr0 netdev=eth0 $script start vifnum=1 bridge=xenbr1 netdev=dummy0 $script start vifnum=2 bridge=xenbr2 netdev=dummy1 ;; stop) $script stop vifnum=0 bridge=xenbr0 netdev=eth0 $script stop vifnum=1 bridge=xenbr1 netdev=dummy0 $script stop vifnum=2 bridge=xenbr2 netdev=dummy1 ;; status) $script status ;; *) echo 'Unknown command: ' $1 echo 'Valid commands are: start, stop, status' exit 1 ;; esac What am I missing? I'd like the guests to auto-start when the host starts, but this is preventing that. --Tim __________________________________________________________________________ / I never thought that I'd see the day where Netscape is free software and \ | X11 is proprietary.

Then you just disable Xen's method with ``(network-script /bin/true)''. The great thing about this is that you can handle bonding, VLANs, and bridges all in the same spot and at the same time. Example bridge interface /etc/sysconfig/network-scripts/ifcfg-xenbr0: DEVICE=xenbr0 TYPE=Bridge BOOTPROTO=none NETWORK=192.168.0.0 NETMASK=255.255.255.0 IPADDR=192.168.0.1 ONBOOT=yes DELAY=0 STP=on Example bridge port interface /etc/sysconfig/network-scripts/ifcfg-eth0: DEVICE=eth0 BOOTPROTO=none ONBOOT=yes USERCTL=no BRIDGE=xenbr0> Here is /etc/xen/scripts/network-custom: > > # !/bin/bash > # network-customMaybe your shebang is busted? -- Christopher G.
