Hi,

in my three node PVE6 cluster I have set up a full mesh network with 25G adapters to provide a low latency storage network (Method 2) for Ceph according to the Wiki Entry. Storage is working great.

Now, I wanted to use this network also as the migration network to leverage its speed. I have set set the migration option in datacenter.cfg accordingly. Now, when I try to migrate a VM, the system says: could not get migration ip: multiple IP address configured for network 'x.x.x.1/24'
It seems that the migration fails due to a preliminary test. Is there anything I could do make this working?

The test fails because in the meshed configuration it finds two interfaces with the same IP address / network.

You can open a new bug report [0] but on the other hand I don't think it is a good idea to have the migration network on the same physical link as your Ceph network. This calls for troubles when the migration starts to utilize the full bandwidth.
