Re: [Xen-users] One physical NIC and multiple bridges
Maresa Nirwan escreveu:
I followed this guide
http://wiki.xensource.com/xenwiki/XenNetworkingExamples.
One of the caveats that was making it not working for me is that in Xen
3.2, the default bridge name is the name of the physical network card.
E.g if you physical network card is eth0, then your bridge name is
eth0. (see
http://wiki.xensource.com/xenwiki/XenNetworking#head-708d4c55f42b5e2b866c06e1ae69530e8c748799)
and compare 3.1 and 3.2 networking, especially bridge name.
Once I realized that the bridge name is my physical NIC name instead of
xenbr0 or xenbr1, I was able to get them to work perfectly fine. The
VMs that only has Dummy0 bridge (the one with local IP) is then NAT so
that they can still access internet (for updates, installing packages,
etc).
There's only 1 more caveat that I'm yet to solve: that is, I'm loosing
source IP on the VMs. E.g. on my HTTP VM, when I access from remote, on
Apache's access log, it is logged as connection from my Dom0 IP address
instead of the real source IP address. It happen for all connections,
not just HTTP.
Hope this helps.

Great!
you and Gordon helped me a lot.
Since I had to use multiple dummy interfaces, I found how to make it in
2.6 kernel (using option numdummies=3 for dummy module).
So, now Im running the exact scenario that I wanted:
4 domUs, 4 bridges (3 of that attached to dummy interfaces on dum0).
Thank you all very much!
