Change deployment host

Community Support
1

Hi,

After a successful undeployment of a VM I have clicked the resume button in sunstone web interface.

Opennebula scheduler has chosen a new host that it is not properly working. I have powered off the host (sunstone has marked the powered-off host as ERROR what it is correct).

Now, I’d like to deploy my VM on another host but i’m not able to change the host

All options in Sunstone are disabled but “Recover” that does not fix the problem as system always is trying to deploy the VM on a powered off host.

Is there any way to change the deployment host?

Thanks a lot in advance,

Versions of the related components and OS (frontend, hypervisors, VMs):
Opennebula 5.4
KVM

Expected results:

You may try to use cli: onevm deploy <vm_id> <host_id> to force the specific host https://docs.opennebula.org/doc/5.4/cli/onevm.1.html
Before this try to get the information about the state of the VM, using onevm show <vm_id>, as
you may need to execute other onevm commands before being able to deploy again.
