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;
