I'm trying to be able to toggle an additional IP address between two guests (qdio GLAN, VM's TCPIP is the router). VM 4.3, SLES 8 SP3 guests.
Our VM guy added the additional three devices required for QDIO on one guest, and then a different three on another. I could have one of the guests listen to its second interface with something like: ifconfig eth1 10.176.137.3 mtu 1400 netmask 255.255.255.128 broadcast 10.176.137.127 and then bring it down with ifconfig eth1 down. It's dmesg is: qeth: loading qeth S/390 OSA-Express driver ($Revision: 1.337.4.16 $/$Revision: 1.113.4.5 $/$Revision: 1.42.4.3 $:IPv6:VLAN) qeth: allocated 0 spare buffers qeth: Trying to use card with devnos 0x740/0x741/0x742 qeth: Device 0x740/0x741/0x742 is a Guest LAN QDIO card (level: V434) with link type Gigabit Eth (portname: VMGLAN) qeth: VLAN not supported on eth1 qeth: IPv6 not supported on eth1 qeth: Broadcast packets will not be echoed back on eth1. qeth: Trying to use card with devnos 0x71C/0x71D/0x71E qeth: Device 0x71C/0x71D/0x71E is a Guest LAN QDIO card (level: V434) with link type Gigabit Eth (portname: VMGLAN) qeth: VLAN not supported on eth0 qeth: IPv6 not supported on eth0 qeth: Broadcast packets will not be echoed back on eth0. eth0: no IPv6 routers present eth1: no IPv6 routers present eth1: no IPv6 routers present eth1: no IPv6 routers present eth1: no IPv6 routers present I enabled/disabled eth1 a few times here. The other server, however, gets this error: # ifconfig eth1 10.176.137.3 mtu 1400 netmask 255.255.255.128 broadcast 10.176.137.127 SIOCSIFADDR: No such device eth1: unknown interface: No such device SIOCSIFMTU: No such device SIOCSIFNETMASK: No such device SIOCSIFBRDADDR: No such device eth1: unknown interface: No such device I also noticed the detected duplicate devicename eth0 error in dmesg, and no messages about eth1: qdio: loading QDIO base support version 2 ($Revision: 1.145.4.1 $/$Revision: 1.66.4.1 $) IPsec Security Association Database (SADB): initialized.

Both servers only have ifcfg-eth0 and ifcfg-lo config files in /etc/sysconfig/network. They both have: alias eth0 qeth alias eth1 qeth at the bottom of modules.conf. The files are exactly the same on both servers. And they both look OK for chandev.conf: The one that works: noauto;qeth0,0x071c,0x071d,0x071e;add_parms,0x10,0x071c,0x071e,portname: VMGLAN noauto;qeth1,0x0740,0x0741,0x0742;add_parms,0x10,0x0740,0x0742,portname: VMGLAN The one that doesn't work: noauto;qeth0,0x0710,0x0711,0x0712;add_parms,0x10,0x0710,0x0712,portname: VMGLAN noauto;qeth0,0x073c,0x073d,0x073e;add_parms,0x10,0x073c,0x073e,portname: VMGLAN Any ideas what might be causing the problem? Also, any idea why I get the "Broadcast packets will not be echoed back on eth0." messages?
