Re: [Xen-users] xen guest eth1 tun interface goes to the wrong bridge
Sorry by "didn't work" I meant after a recompile ("make clean", "make
world", "make install" probably not all necessary but I am a bit of
noob) I was in exactly the same position I was in before, with the tun1
and tun2 being assigned to the same bridge.

Which bit didn't work? I take it you changed wrapper script and
updated /etc/xen/xend-config.sxp with something like -
(network-script network-bridge)
to
(network-script network-bridge-wrapper)
BTW - None of those * (stars) should have been there, my email client
was doing something odd. This solution definitely works for us.

Thanks for the info, didn't work for me though.
Think I'll try 3.03 next, maybe that'll work.

I'm pretty sure we had the same issue as you. After posting to the
dev list and getting no response my colleague fixed it by modifying
/xen-3.0.2-2/tools/ioemu/vl.c and changing
pstrcpy(ifr.ifr_name, IFNAMSIZ, "tun%d");
line to
*sprintf(ifr.ifr_name, "tun%d.%%d", domid);
and running:*
*/etc/xen/scripts/network-bridge start bridge=xenbr0 netdev=eth0
vifnum=0
/etc/xen/scripts/network-bridge start bridge=xenbr1 netdev=eth1
vifnum=1*
*as our wrapper script
Our brctl show now looks like this:
bridge name bridge id STP enabled interfaces
xenbr0 8000.b2b6111693ac no peth0
tun1.0
vif0.0
xenbr1 8000.d63bb36ceb1e no peth1
tun1.1
vif0.1
Hope this helps.

I've got the same problem with xen 3.0.2 (compiled form source, but
I've had the same issue with binaries) running on Ubuntu 6.06.
I've got two network cards and have a wrapper script around
network-bridge to create two bridges.
When I run a paravirtualised domain which has the following vif
section:
vif = ['bridge=xenbr0','bridge=xenbr1']
I get a domain with two vifs that attach to the correct physical
interfaces. Which is what I'd expect.
However...
When I create a HVM domain with this vif section:
vif = ['type=ioemu, bridge=xenbr0','type=ioemu, bridge=xenbr1']
I get two vifs but both attached to the same bridge (whichever
bridge appears first in the script, the above example would attach
both to xenbr0)
brclt show looks like this:
xenbr0 ===> 8000.someStuff ====> vif0.0 peth0 vif12.1
xenbr1 ===> 8000.otherStuff ====> vif0.1 peth1 tun0 tun1 vif12.0
so any thoughts?
many thanks

Hello,
We have setup 6 xen guests VT(rhel3) on dmo0 FC5 and for each guest
there are 2 network interfaces eth0/eth1.
Now if we start the xen guests all the tun interfaces for eth1 goes
to xenbr1 and not do the defined bridge tsmbr1 oder tsmbr2 ?
Where are the scripts for setup tun interface ?
Has anybody a solution for this problem ?
2 Guests have this vif config:
vif = [ 'type=ioemu,bridge=xenbr1,mac=02:00:00:00:01:01',
'type=ioemu,bridge=tsmbr1,mac=02:00:00:00:01:02' ]
And 2 guest have this vif config:
vif = [ 'type=ioemu,bridge=xenbr1,mac=02:00:00:00:01:09',
'type=ioemu,bridge=tsmbr2,mac=02:00:00:00:01:10' ]
bridge name bridge id STP enabled interfaces
tsmbr1 8000.921f6ab823a2 no tun1

tsmbr2 8000.feffffffffff no vif3.1
