@steven3579 , it seems to me the expected and actual both contain the same error message. Is there something that does not behave as expected?
Can you make the backup directly with networker?

[rajujith]

@steven3579 Can you cross-check the following:

• KVM hosts are added as a client on the Networker with Globals (1 of 2) configured as per the plugin documentation.
• Cluster is created as a dummy/placeholder client on the Networker with Globals (2 of 2) configured as per the plugin documentation.

[rohityadavcloud]

This plugins uses KVM host username/password credentials to ssh, so might not be acceptable for all users but that's the plugin specific requirement.

[fermosan]

Yes. I confirm that it is using user/password. @steven3579 Are you using public keys to connect to hosts ?

[steven3579]

Hi @fermosan
Yes. I using pulic keys connect KVM host. Do you have any way to address the issue?

[fermosan]

If it is crucial for you and provided that we have the time we can implement support for public keys as well for the release after 4.20. Let me know. In the meantime, as a workaround you could populate the host user/pass fields in the database with a valid account on the KVM hosts (with root privileges) and it will work.

Hi @fermosan
Yes. I can try. please add Milestone version let me excel at my convenience.
