Hi Xen folks, I have a question where I couldn''t find the answer on google or in the archives... I have a statically compiled xenU kernel, and I want a XEN guest with 2 network interfaces. My config looks like this: name = "myname" kernel = "/boot/vmlinuz-2.6-xenU" memory = 256 vif = [ ''bridge=br701'', ''bridge=br9'' ] disk = [ ''phy:vg0/myname,hda1,w'',''phy:vg0/myname_swap,hda2,w'' ] ip="1.2.3.4" netmask="255.255.255.0" root = "/dev/hda1 ro" extra = "2" Unfortunately the interface order in the (Linux)-Guest seems to be random. This means after booting the guest the IP 1.2.3.4 is assigned to either br701 or br9, but it''s always random (both interfaces work in the guest though). If I define mac-addressses for the interfaces there is no difference. Can I somehow "lock" those interfaces? I don''t know how. I''d appreciate your help! wogri -- wogri@wogri.com http://www.wogri.com http://www.einradfilm.at _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I have the following in my config:
vif = [ ''mac=00:16:3e:00:00:00, bridge=xenbr0'',
''mac=00:16:3e:00:00:01, bridge=xenbr1'' ]
I have no IP-config in the xen-config file, I do that in the guest itself.
In xend-config.sxp I have: (network-script network-custom-bridge)
And my network-custom-bridge script looks like this:
#!/bin/bash
dir=$(dirname "$0")
"$dir/network-bridge" "$@" vifnum=0 netdev=eth0
bridge=xenbr0
"$dir/network-bridge" "$@" vifnum=1 netdev=eth1
bridge=xenbr1
This works fine for me.
Good luck,
Kris

Hi Xen folks,
I have a question where I couldn''t find the answer on google or in
the archives...
I have a statically compiled xenU kernel, and I want a XEN guest with
2 network interfaces. My config looks like this:
name = "myname"
kernel = "/boot/vmlinuz-2.6-xenU"
memory = 256
vif = [ ''bridge=br701'', ''bridge=br9'' ]
disk = [
''phy:vg0/myname,hda1,w'',''phy:vg0/myname_swap,hda2,w''
]
ip="1.2.3.4"
netmask="255.255.255.0"
root = "/dev/hda1 ro"
extra = "2"
Unfortunately the interface order in the (Linux)-Guest seems to be
random. This means after booting the guest the IP 1.2.3.4 is assigned
to either br701 or br9, but it''s always random (both interfaces work
in the guest though). If I define mac-addressses for the interfaces
there is no difference. Can I somehow "lock" those interfaces? I
don''t know how. I''d appreciate your help!

Thanks for that information!
Do you have a customized vif-script as well?
It seems that your custom-bridge does the same I do in my "static
(with /etc/network/interfaces in debian) configuration - I create
bridges to "physical" interfaces:
iface br9 inet manual
up brctl addbr br9
up ip link set br9 up
up brctl addif br9 vlan9
down brctl delif br9 vlan9
down ip link set br9 down
down brctl delbr br9
iface vlan9 inet manual
pre-up vconfig set_name_type VLAN_PLUS_VID_NO_PAD
pre-up vconfig add eth0 9
pre-up ip link set vlan9 address 00:16:3e:09:01:01 arp off
up ip link set vlan9 up
down ip link set vlan9 down
post-down vconfig rem vlan9
... and so on...
But I think that the vif-part is the "faulty" one.

Just something like this in /etc/network/interfaces (debian guest): auto eth0 iface eth0 inet static address x.x.x.x netmask x.x.x.x broadcast x.x.x.x gateway x.x.x.x and the same way for eth1..

Under RedHat and its ilk, it''s in /etc/sysconfig/ntework-scripts/ifcfg-eth0 and is the HWADDR setting. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
