Is it possible to get ssh connection to non-host VM in LAGO?

It is easy for host vm and engine, there is method ''ssh" in ovirt-engine-api-model.

Please give me advice, can Iget connection to vm0 in a similar way?

I would start first by making sure the VM is booting properly using SPICE from the GUI, when the tests ends, you should be able to log into the Engine GUI(run 'lago ovirt status' inside your deployment directory to get the link, the directory should be something like ovirt-system-tests/deployment-SUITE-NAME). Then in the GUI, start the VM and click on 'console', the username/password should be root/123456.

If it is booting properly - first would be to check if it even gets an IP(my guess is not - I'm not even sure if dhcp is running in that layer, maybe we should setup one..).

And a second question is about ssh to this vm connection from my laptop's console. According run_vm test from 004_basic_sanity.py ( https://github.com/oVirt/ovirt-system-tests/blob/master/basic-suite-maste... ) vm0 should contain interface with ip 192.168.200.200, but ping this from engine (192.168.200.4) Destination Host Unreachable. And 'ping vm0' defined vm0 as 192.168.201.213 and also couldn't reach vm0.

And in webadmin (https://engine/ovirt-engine/webadmin/#vms) IP Address field is empty.

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 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.

But we should be able to use the Yaniv's suggestion: > 2017-05-31 23:06 GMT+03:00 Yaniv Kaul <ykaul(a)redhat.com&gt;: [...] >> 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).
