Changing Hypervisor IP Addresses
Hi Everybody-
We set up our OVM cluster's networking, initially, in a very simple "get it working for testing" setup and need to make it more robust, utilizing all four network interfaces. We want to use two ports for management and migration and two ports for production traffic. In order to do this, the management interface has to be moved to a different subnet with different IP addresses. Currently the hypervisors are in DNS.
How can we safely make the change (downtime is acceptable for this) without losing other configurations? Our biggest concern is the hypervisor IP address change, both how to make the change itself and how to then get the pool back in order with the new IPs.
