Hi, I have some troubles with the live migration mechanism of OpenStack and my setup:
Our compute nodes have two types interfaces with different things running on top of them. 1GbE interface: - interface to access the hypervisor OS - hypervisor access to the core infra services (dns, ntp, syslog, ...). The FQDN of the compute node is bound to the IP of this interface, let's say compute0.mydomain.com, compute1.mydomain.com, ... 10 GbE interfaces: - redundant network, internal to the openstack cloud - multiple VLANs on top of it to segregate the different services - api / db - CEPH cluster network - CEPH public network - ... - A second FQDN is bound to the api / db interface IP address, let's say compute0-api.mydomain.com Problem is that when I want to live migrate instance, the Nova driver tries to connect to the compute0.mydomain.com IP address. It's working but it's far from ideal (slow network, not redundant, not designed to move internal OpenStack network flows, ...). Ideally I'd like to be able to use the FQDN that is bound to the api / db network. It seems that there is no option on nova to set a specific fqdn for the ssh live migration, maybe the solution would be to code it ? Suggestions are welcome !
