Hi: I have two HVM domU ubuntu 10.04 Lts and Window XP running. I have assigned PCIe device to each of this domU. I would like to communicate these two VM. Can anyone give me some idea on how to do. I did some research on IVC but unable to get answer. Anything will be appreciated.

I am little bit confuse on do I have to build an external code or just modify the xen source code for this?Do you know any documentation related to this? I found some but all are talking only about the performance. But I am looking for something how to do this.

That said; Build a normal bridge in the OS, the use ''virsh'' to attach a new vifX.Y interface between the domU and dom0 bridge. I''ve covered the building of bridges in a RHEL 5.6 based tutorial using Xen 3.0 here, perhaps it will help. It also covers the networking in Xen in general: http://wiki.alteeve.com/index.php/Red_Hat_Cluster_Service_2_Tutorial#Setting_Up_Xen -- Digimer E-Mail: digimer@alteeve.com Freenode handle: digimer Papers and Projects: http://alteeve.com Node Assassin: http://nodeassassin.org "I feel confined, only free to expand myself within boundaries." _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

My OS is Ubuntu 10.04 lts and using xen 4.0.
I will give a try on both. However, I don''t want to share. I will post
the result.Thank you

Simply setup an extra interface on each VM, on the same IP subnet and
they''ll communicate to each other :)
i.e. something like:
ifconfig eth0:0 192.168.2.1
and then on the other VM
ifconfig eth0:0 192.168.2.2
This works, but it shares the network traffic with the same network as the
existing traffic. This is possibly a security issue if the existing network is
not fully trusted.

If the 2 VM''s are on the same Hypervisor, and they''re using
a IP subnet which other hosts don''t use then it doesn''t get
"shared".
Use VLAN if you need security :)

However, I don''t want to share.You can create another bridge in the Dom0 which does *NOT* have a real interface connected to it. You can then create two IVFs for each DomU - one connected to the bridge with an external interface, the other connected to the internal bridge. Traffic on the internal bridge will be invisible to the outside world. Eg, if you current bridge is br0, then you can create a new one by : brctl addbr br1 then just connect each DomU to br0 and br1 -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
