[Xen-users] /etc/sysconfig/network-scripts, are they executed in xen startup
I have a few Xen domu''s that run multiple ip''s on the same bridge. For example root@fg4x2 network-scripts]# cat ifcfg-eth0 # Intel Corporation 82541GI Gigabit Ethernet Controller DEVICE=eth0 BOOTPROTO=static BROADCAST=131.225.107.255 HWADDR=00:16:3E:05:04:02 IPADDR=131.225.107.112 NETMASK=255.255.255.0 NETWORK=131.225.107.0 ONBOOT=yes root@fg4x2 network-scripts]# cat ifcfg-eth0:160 DEVICE=eth0:160 BOOTPROTO=static BROADCAST=131.225.107.255 IPADDR=131.225.107.160 NETMASK=255.255.255.0 NETWORK=131.225.107.0 ONBOOT=yes TYPE=Ethernet On this particular domU, the 131.225.107.160 ip is not activated at boot, even though onboot=yes. (This domU is based on Sci. Linux 5.1 which is like redhat and centos). On another different domU, I have a case where an extra ip is activated at boot, even though I specify onboot=no. That domU is based on Sci. Linux 4.x which is like redhat and centos). My questions: 1) What is it in the startup of a domU xen OS that determines which parts of /etc/sysconfig/network-scripts are executed and which are not? Obviously the machine has some ip from the beginning well before you get to the /etc/rc.d/rc3.d scriptgs. 2) What is it within the xen startup which causes the files ifcfg-eth0 and ifcfg-eth1 to be renamed to ifcfg-eth0.bak and ifcfg-eth1.bak sometimes? Any help is appreciated. Thanks Steve Timm -- ------------------------------------------------------------------ Steven C.
