Hi, Is it possible to configure a domU with multiple IP addresses? i.e. (v)eth0 and (v)eth0:0, or (v)eth0 and lo:0 I can add the additional interface in the domU just fine so that it shows up in ifconfig, but the bridge doesn''t seem to do its magic to make it accessible. vif = [ ''bridge=xenbr0'', ''bridge=xenbr0'' ] The docs tend to indicate that vifx.1 will always go to (v)eth1, but unfortunately I can''t get the bridge to do (v)eth1 either :( Thanks in advance, Roger -- ---------------------------------------- Ninth Avenue Software p: +61 7 3870 8494 (UTC +10) f: +61 7 3870 8491 w: http://www.ninthavenue.com.au e: info@ninthavenue.com.au ---------------------------------------- _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Nicholas, Thanks for your reply.>>Is it possible to configure a domU with multiple IP addresses? > > Use eth0, eth0:0, etc in the domU itself for simple aliases.Yep, thats what I''m doing, but I cannot ping this interface (eth0:0) from external hosts, or dom0. I figured it must be a bridging issue.

I figured it must be a bridging issue.Are you using antispoof ? If so, it sets up iptables rules that allow only packets to/from allocated ip (in config file) to go through the vifX.0 interface.

I figured it must be a bridging issue.Seems to have been an ospf issue.
