Subject: [Xen-users] More network problems
I thought I had XEN networking down fairly well but I have since run
into a sort of chicken and egg problem.
I set up my master server as I noted in an earlier post. This machine
has bonded NIC''s each sitting on trunked switch ports. I have a vlan
set up and am able to ping the gateway without issue. Now, I want to
add a second server to the pool.
If I understand correctly, once it is added to the pool it should
inherit the bonding, vlans, etc... set up on the master. The problem is
that the second server can not see the master to join until it is on the
network.
I thought, no problem, I will bootstrap it by setting up the management
vlan on this second server and then joining it to the pool. Well I got
the management vlan set up on this machine and can ping the gateway but
Xen complains that I must have a physical NIC set up as the management
port before I can join a pool (which I guess makes sense since the pool
will take over control of the virtual interfaces).
Maybe this will all make sense tomorrow after I sleep on it but, does
any one have any suggestions?
I am getting brain tied (similar to tongue tied only worse) every time I
try to sort out the relationship between the PIF''s, VIF''s,
Network''s,
Vlans, Bridges, actual physical NIC''s, output of ifconfig, etc... and
which ones I need to connect to which to make things work. I had it
figured out at one point (I think) but that was before I tossed vlans
into the mix.
My cloudy general idea of how it works is that: physical interfaces are
tied to virtual switches (networks) and those switches have interfaces
pifs. Vifs are attached to the pifs and can be plugged into virtual
machines.
Am I close?
Thanks for your help;
