Description

If the migration and ovrtmgmt networks are two distinct networks with 2 distinct subnets that the source address selection during migration will be depend on the address in the migration URI. If the destination address is on the ovrtmgmt network that network will be used. In case of DNS where both addresses are in DNS under the same name, you might see some round-robin effect as DNS by default will switch the order of returned addresses (you can see that using 'dig' tool). As Daniel said in BZ 971394, this should be achieved with proper route table configuration. The natural way to control the routing of packets to a certain destination is by making changes to the routing tables. I am not sure that I understand the use case and the problem. Anyhow. Can you have two destination addresses (migration & mgt), and set up the routing tables on the source (and dst) such that every one of these destination addresses is routed through a different source NICs (subnet). Let's look for a standard configuration based solution, and avoid writing specific code. The libvirt related bug is closed. The proper way to solve this is through routing policy table. Closing the bug. |
