I may use a pakamiko only like this : https://github.com/vmakarova/ovirt-system-tests/commit/ 3e9e5ce697da7e0567aaad8397fa886469bc5ae3 Lago also use pakamiko, so there is not new dependencies.
Is this a good way?
If we don't have higher level means to access VMs via ssh in Lago/Ovirt-System-Tests (do we?) then I'd say using paramiko is fine.
And few more questions about tests and ovirt network.
1) This address of vm0 192.168.201.213. What is this addres? Why it is ip of 'vm0'? What gave it to vm0 and how the user may to understand that the address would be that? There is not this ip in virsh net-list and net-dumpxml
It's probably obtained from DHCP, it's in the DHCP range specified in LagoInitFile (*.100-*.254).
2) In test vm_run (004_basic_sanity) we configure interface eth0 on vm0 with ip 192.168.200.200. But this interface is unreacheble from engine-host.And when I ask vm0 'ip address' via ssh, there is not interface eth1 there. What for does test add it, if it does not work? Should it work? And why test finished successful if eth0 was not configured according a start_params?
Good questions. The complex setup in vm_run looks somewhat mysterious. But we should be able to use the Yaniv's suggestion:

We can add a fake entry in Lago init file just as we do for hosted-engine. Most importantly, it'll create a MAC to IP address mapping in libvirt's DHCP. Of course, then we need to use this MAC.
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).
