I’ve got a http://www.hetzner.de/en/hosting/produkte_rootserver/eq4 Hetzner EQ4 server running Centos in which I want to run a Linux VM (distro doesn’t matter but probably Ubuntu) and a Windows 2008 VM (possibly 2 of latter). I have installed XEN and can get a test Centos VM and a W2008 VM running okay in bridged mode but I’m seriously struggling to get routed networking up and running which I need so that I can access the machines directly using the extra IP’s that Hetzner have supplied. The error I’m getting is "Error: Device 0 (vif) could not be connected. /etc/xen/scripts/vif-route failed; error detected." and my gut feeling is that this has something to do with the way the IPs are set up; although a seasoned Windows user, I’m still little more than a newbie to Linux so I may be making some fundamental errors here :confused: First question is do the additional IP’s need to be set up before I do anything with the VMs? I’ve been following the tutorials http://www.howtoforge.com/centos_5.0_xen here and http://www.virtuatopia.com/index.php/Virtualizing_Windows_Server_2008_with_Xen here and they don’t mention that but I’m guessing that the server needs to know about the IPs before they can be used. I have tried setting them up using ifcfg-eth0:1, ifcfg-eth0:2, ifcfg-eth0:3 but they do not respond to ping. When I change to routing, however, using the instructions http://www.howtoforge.com/how-to-enable-networking-in-xen-guests-on-hetzners-new-eq-servers-debian-lenny here , I cannot get the VMs to start, they return "Error: Device 0 (vif) could not be connected. /etc/xen/scripts/vif-route failed; error detected." I’m also confused about the settings to use for these IP’s. Hetzner have a funny way of issuing the additional IP’s, you have to request them individually which means you do not necessarily end up with contiguous addresses, here is what they gave me: Main IP: DEVICE=eth0 BOOTPROTO=static BROADCAST=78.xx.xx.63 HWADDR=40:61:86:e9:d4:ae IPADDR=78.xx.xx.55 NETMASK=255.255.255.255 SCOPE="peer 78.xx.x.33" (Note: for some reason, I have written in my original notes that the Netmask should be 255.255.255.224 but 255.255.255.255 is what is showing after a reinstall. Could that be an error?) The first additional IP is 78.xx.xx.45; I did not receive any instructions for that but I presume the netmask, and broadcast are the same. My other two additional IPs are 178.nn.nn.157 and 178.nn.nn.157, i.e a completely different group. The other details supplied for those two IPs are Gateway: 178.nn.nn.145 Mask: 255.255.255.240 As far as I can make out, in Xen networking, all the additional IPs should point to the main IP as their gateway so should I just ignore the gateway settings that Hetzner provided by email and set all the gateways to the main IP 78.xx.xx.55? Also, how to I treat the different netmaks in the two pairs of IP? Final question - sorry for so many :) - is what is the significance of "SCOPE" in the main IP rather than GATEWAY? -------------------------------------- *Those instructions are actually for Debian but I''ve made the appropriate changes for Centos; I''m not that bothered about what distribution Dom0 runs on so I tried it with Debian, same problem with Error: Device 0 (vif) could not be connected... -- View this message in context: http://old.nabble.com/XEN%5CCentos%5CNetworking-tp29027182p29027182.html Sent from the Xen - User mailing list archive at Nabble.com. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
