Re: [Xen-users] Ubuntu Gutsy Xen problems : DomU n/w not working

["Emre Erenoglu" <erenoglu@xxxxxxxxx>]

Hi JD,

 

Personally, I found Xen on Ubuntu Gutsy extremely problematic and broken. I could not use it even though I tried hard.

 

I removed xen packages of Gutsy and now running xen-unstable that I've compiled myself with 2.6.18 kernel. Works very stable. I recommend you to do the same thing instead of spending your time.

 

After you manually make the bridge and have network in DomU, did you check the ifconfig -a output of your dom0? Maybe it's just missing an IP address?

 

Best regards,

 

Emre

Hi
  I am mainly a Fedora user but I am trying to use
Xen on Ubuntu. I installed the ubuntu-server-xen
package. And my system is upto date. Also have
network-script to  network-bridge and vif-script to
vif-bridge. Added loop_max=64 to the /etc/modules.

Problem
=======
The  domU N/w is not working

the bridge does not seem to have any interfaces. On
Fedora it had peth0 and vif0.0. The Ubuntu
distribution is having veth0.. interfaces.

brctl show
bridge name     bridge id               STP enabled
 interfaces
xenbr0          8000.feffffffffff       no


As I start the VMs the vif<domid>.0 interfaces do get
added. But the domU does not get the n/w (as I think
the other end of the bridge is not setup correctly).
This is true for both PV and HVM guests

I tried to add manually veth0, brctl fails with
invalid argument.
I tried adding vif0.0 and eth0. With this my domU n/w
worked but dom0 n/w is lost.!!

Any ideas on how to resolve this.

Thanks
/Jd
