RE: [Xen-users] Conflict with Xen bridge?
Daniel, I am new to using Linux and Xen but here is what I have had to do to
get Xebr0 working.
When you do the install, you are asked to use DHCP or manually input and IP.
When using DHCP I couldn't get Xenbro to come up as an option when I started
using Paravirtualization (gui one) as an option. Only option I had was VIRTUAL
and using the vifxx option. When I rebuilt using an assigned (manual) IP Xenbr0
became an option and everything worked - each VM was assigned an IP and could
be seen outside our firewall.
I have rebuilt these machines about 20 times (one PE2950 housing three virtual
RHEL5 OS connected to an EMC array)now since we are migrating off our IBM
mainframe to a RedHat/Jboss/MySQL alternative. So while programmers are working
on Java I have been playing with options for Linux/RHEL5.1 and Xen connected to
a EMC CX-10c.
A newbie here but hope that helps.
Tony

Mmmm... executing by hand the previous line, I got the following output.
I suspect that it is the cause because of which the wrapper script don't work.
ifdown: interface eth0 not configured
SIOCSIFNAME: Device or resource busy
But vifnum=1 causes that it loses the connectivity with LAN and Internet. Some
idea about why it can happen?

Thanks for your time. I will try to read about advanced networking
configuration with Xen. But I will accept any suggestion or comment that you
can give me :-)

Daniel
