Question

Different restore results with VRO

Hi everyone,

I noticed an interesting behavior during DataLab testing. Multiple runs of the same DataLab test are producing different restore outcomes.

For example, in one run, VM A completes with an error, while in the next run the same VM completes successfully. I have also seen the opposite behavior with another VM.

I would have expected the test results to be consistent and repeatable, especially since nothing has changed in the environment between the runs.

Most of the VMs involved are running older versions of Oracle Linux Server.

Has anyone else observed this behavior before?

Kind regards,
Chris

Hi Chris, what are the errors you’re getting?

Hi Paul,

mostly it’s “Failed to find any network connections for the VM” and “Failed to get IP address”. The VM use DHCP but the DHCP server was restored, too. And even the DHCP server and affected VM are in different VLANs the virtual lab is configured to route the traffic.

EDIT: Sometimes the restored VM didn’t have an vNIC configured

@Madi.Cristil ​@safiya - maybe we move this to the VRO Heros Den for better help.

Hi everyone!

I did a manual restore of the VM which has no vNIC after restoring with VRO. When restoring the VM manual using full VM restore, the NIC is configured on the VM. This is weird.

Is it possible that during some runs, the timeouts are reached before the VM is ready? If you compare a successful and failed run, do you see any tasks taking more time than usual?

Does this only occur on your Linux VMs or do you have the same issue with your Windows Workloads? Depending on your Linux Distribution and/or VM-configuration, it could be, that the restored VM has no information about it’s “new” NIC / eth Interface...
