It has been brought to my attention that when doing live-migration between compute-nodes it fails with "Host key verification failed", event if the following has been setted :
$juju set nova-compute-kvm enable-live-migration=True
$juju set nova-compute-kvm migration-auth-type=ssh
In this case, this is a Autopilot/Landscape deployment, the compute-node-kvm has two nics eth0 (x.x.x.x/x) subnet and juju-br0 (eth4) (y.y.y.y/y) subnet.
The same problem also occurred when adding a new compute-node unit.
Live migration doesn't work :
"... ERROR nova.virt.libvirt.driver .... Live Migration failure: operation failed: Failed to connect to remote libvirt URI qemu+ssh://<HOST>/system: Cannot recv data: Host key verification failed.: Connection reset by peer"
$ juju run --unit nova-cloud-controller/0 "unit-get private-address"
<IP_OF_JUJU_BR0_SUBNET>
$ juju run --unit nova-cloud-controller/0 "unit-get public-address"
<IP_OF_JUJU_BR0_SUBNET>
$ juju run --unit nova-compute-kvm/0 "unit-get private-address"
<IP_OF_JUJU_BR0_SUBNET>
$ juju run --unit nova-compute-kvm/0 "unit-get private-address"
<IP_OF_JUJU_BR0_SUBNET>
If ssh by hand as user 'root'
$ ssh root@<IP_OF_ETH0_SUBNET>, is working
$ ssh root@<IP_OF_JUJU_BR0_SUBNET>, is not working
Workarounds :
1- Delete the offending entries in /root/.ssh/known_hosts
2- Set "StrictHostKeyChecking no"
3- As mentioned above : $ ssh-keyscan -t rsa node-b | sudo tee -a /root/.ssh/known_hosts
....

$juju set nova-compute-kvm enable-live-migration=True
$juju set nova-compute-kvm migration-auth-type=ssh
In this case, this is a Autopilot/Landscape deployment (where the charm version are pinned), the compute-node-kvm has two nics eth0 (x.x.x.x/x) subnet and juju-br0 (eth4) (y.y.y.y/y) subnet.
The same problem also occurred when adding new machines (compute-node) unit.

$ ssh root@<IP_OF_ETH0_SUBNET>, is working without complaining about offending key for ip.
$ ssh root@<IP_OF_JUJU_BR0_SUBNET>, is not working complaining about the offending key for ip.
Some workarounds :
* Manually remove the offending entries in /root/.ssh/known_hosts
* Set "StrictHostKeyChecking no" and restart ssh.
