Hi,
I am trying to setup Tashi in a cluster environment. My configuration is
as follows:
Host B (Node Manager)
Host A /
(Cluster Manager)\
Host C (Node Manager)
I am using the Qemu backend and using Virtual Bridges for VM connectivity.
In my current setup, I am creating Virtual Bridges on Hosts A, B and C.
All three virtual bridges are part of the same subnet (192.168.2.*)
When I create a new VM, it gets successfully created on one of B/C. I can
easily ping/ssh into the VM from whichever host it is created on. However,
my application requires it to be reachable/sshable from host A as well.
Host A can ping the virtual bridges on B and C (and vice-versa as well).
Also, the VM can ping the virtual bridge on the host but not other nodes.
Is there anything I am missing in my setup? The outputs for "ifconfig" and
"ip route show" for all three hosts are as below.
Thanks,
