Re: [Xen-users] two bridges with xen 3.2.0
Hi, i tried something new....
i read somewhere that the problem now was that i had not installed
hotplug on my debian.
i did this:
********
# apt-get install hotplug

The thing is that it removed 2 different paquets, "initramfs-tools" and
"udev", which i don't if xen needs.
anyway... after that, i keep getting the same error;
**********
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.
**********
any idea?

Hi guys,
let's see...
i've got my own script for bridges:
*******
#!/bin/sh
XENDIR="/etc/xen/scripts"
$XENDIR/network-bridge "$@" netdev=eth0 bridge=eth0 vifnum=0
$XENDIR/network-bridge "$@" netdev=eth1 bridge=eth1 vifnum=1
*******
this is my interfaces file
*********
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.200
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.231
auto eth1
iface eth1 inet static
address 192.168.2.200
netmask 255.255.255.0
*********
and virtual machines have this in their conf files:
************
vif = [ 'bridge=eth0', 'bridge=eth1' ]
************
so....
when i try to create the machine... i get this:
**********
Error: Device 0 (vif) could not be connected. Hotplug scripts not
working.
**********
Any idea?
Thank you.

Ok,
/etc/network/interfaces - as you like it, don't change it for xen ..
and xen won't change it.
Here's my config;
(xend-tcp-xmlrpc-server no)
(xend-unix-xmlrpc-server yes)
(xend-api-server ((unix)))
(xend-relocation-server yes)
(xend-relocation-port 8002)
(xend-relocation-address '<my private ip>')
(xend-relocation-hosts-allow '')
(network-script my-network-bridge)
(vif-script vif-bridge)
(dom0-min-mem 196)
(dom0-cpus 0)
(vncpasswd '')
(xend-http-server yes)
(xend-port 8000)
(xend-address '<my private ip>')
(xend-unix-server yes)
(xend-unix-path /var/lib/xend/xend-socket)
Note; I called my script; "my-network-bridge", everything else is
"default".

Hi,
i'm sorry guys, i don't quite get it.
i replaced my script with this one:
***********
#!/bin/sh
XENDIR="/etc/xen/scripts"
$XENDIR/network-bridge "$@" netdev=eth0 bridge=eth0 vifnum=0
$XENDIR/network-bridge "$@" netdev=eth1 bridge=eth1 vifnum=1
***********
on the other hand....
what about /etc/xen/xend-config.sxp ? Do i have to keep the
(vif-script vif-bridge) line? Do i have to use another script?
what about /etc/network/interfaces? can i use something like this?
****************
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.200
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.231
auto eth1
iface eth1 inet static
address 192.168.2.200
netmask 255.255.255.0
****************
or do i have to replace eth0 with peth0 in this file? will debian
load the newtork interfaces if i change the name?
Thank you.

Hi,
Here's my Xen3.2 script .. working 100% on multiple boxes ...
#!/bin/sh
XENDIR="/etc/xen/scripts"
$XENDIR/network-bridge "$@" netdev=eth0 bridge=eth0 vifnum=0
$XENDIR/network-bridge "$@" netdev=eth1 bridge=eth1 vifnum=1
NOTE::
The nice people at Xen changed the default bridge from Xenbr<n> to
eth<n>.
New method;
a. rename device eth0 to peth0
b. create a bridge called eth0 (!!)
c. include peth0 as a device for bridge eth0
!!
Much improved method, however, the documentation stinks ..
Gareth.

hi,
i'm trying the new 3.2.0.
i've always used two bridges since 3.0.x with the following set up:
Replace
(network-script network-bridge)
with
(network-script network-bridge-both)
in file /etc/xen/xend-config.sxp
The content of network-bridge-both is
************
#!/bin/sh
dir=$(dirname "$0")
"$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0
"$dir/network-bridge" "$@" vifnum=1 netdev=eth1 bridge=xenbr1
************
As i said, this used to work for 3.0.x and 3.1.x releases.....
Now, it doesn't work anymore...
when the xen loads....
there's only this in the ifconfig command:
-lo
-peth0
-peth1
What's different from the earlier releases? Thank you.
