Hi!
I am building a KVM cluster that needs VM live migration.
My shared storage as well as the KVM hosts will be running
CentOS.
Because 10 Gbps Ethernet switches are very expensive at the
moment I will connect the KVM hosts to the storage by
cross-over cables and create private networks for each
connection (10.0.0.0/30 and 10.0.0.4/30).
The following diagram shows the topology

My question is: will live migration work in this configuration
since the storage will have 2 different IP addresses
(10.0.0.1 and 10.0.0.5) in 2 different networks even though
it is the same storage?
Thanks!
