[one-users] Permission denied while creating VM

[Jaime Melis]

Hi Tobias,

I have no idea why that's happening to you. I'm wondering, have you tried
start the VM manually in the host after it fails to deploy? the files
should be still there until you do "onevm delete".
$ virsh create /var/lib/one/datastores/0/<vm_id>/deployment.0

Does /var/log/libvirtd/qemu/one-<vm_id>.log shed any light on the issue?

It could be a polkit problem, have you grepped the usual suspects?
auth.log, etc...

cheers,
Jaime
