Lago/Ovirt-System-Tests (do we?) then I'd say using paramiko is fine.

It's probably obtained from DHCP, it's in the DHCP range specified in
LagoInitFile (*.100-*.254).

Good questions. The complex setup in vm_run looks somewhat mysterious.
But we should be able to use the Yaniv's suggestion:

If I understand it correctly:
- We can create a fake VM in LagoInitFile. How do we specify it's fake,
is it the vm-provider entry?
- If we assign IP to that VM, the mapping for DHCP is automatically
created, and the MAC address is determined by lago.utils.ipv4_to_mac.
- Then we can specify `nics' parameter to params.VM constructor or to
add a NIC to the VM as in add_nic test (but I'm not sure sshd would be
available on it in that case).
