Hi All!
I need to setup a virtual host with 2 virtual ethernet interface on
separated bridge.
When the domain1 starts the second ethernet adapter does not connect to the
domain0's second bridge.
When I try to add the interface manually I got an error message.
Can help somebody to me to solve this problem?
Domain0:
Debinan/GNU linux (sarge)
Xen 2.0.1 (with recompiled 2.6.9 kernel)
Domain1:
Debian/GNU linux (sarge)
Xen unmodified vmlinuz-2.6.9-xenU kernel
(when I compile unprivileged kernel I got the following message from
build process:
CC arch/xen/i386/mm/ioremap.o
arch/xen/i386/mm/ioremap.c: In function `__ioremap':
arch/xen/i386/mm/ioremap.c:144: error:

)
Below the commands how I test it:

Why vif4.1 not in xen-br1?
Let's add it manually...
domain0:~# brctl addif vif4.1 xen-br1
can't add xen-br1 to bridge vif4.1: Operation not supported
It gives error message :( What is the problem?
Testing vif4.0...

It's OK.

So, the vif4.1 interface seems to be OK.
Other questions:
- When goes Xen 2.x to debian system?
- How can I define the nic name (vif) before I start a virtual machine?
udv,
