Hi all,
I have 2 network cards on my computer. I want to use :
- eth0 for xen0 host: ip 192.168.1.4
- eth1 for xenU guest: ip 192.168.2.1
guest and host are not on the same network. eth0 is configured when
I start xend (xen-br0->eth0).
I configure eth1 with :
/etc/xen/scripts/network start bridge=xen-br1 netdev=eth1
In my guest domain config, I add vif = [ 'bridge=xen-br1'], but when
I start
my domain, I can't ping machines on network 192.168.2.0/24. ifconfig
on guest show a correct config.
What is your correct config? Please provide it.
And did you verify with brctl show that eth1 is on xen-br1 and working?
What is the contents of the routing table on dom0?
Since the above config should work, any additional info would help
tracking down the problem.
Dirk

For examples, I test the config at home.
