[one-users] root user creates checkpoint directory on cluster node instead of oneadmin

[Pieter Simoens]

Dear all,

when I issue a command "onevm stop VM_ID'', the Virtual Machine stays in 
the save state. On my front-end node, the log-files (both oned.log and 
vm.log) show no specific error.

However, when I have a look at the virsh log-file on my cluster node 
(/var/log/libvirt/qemu/one-22.log), I see the error: "sh: cannot create 
/work/onimages/VM_ID/images/checkpoint: Permission denied".

Strangely enough, the permissions of /work/onimages/VM_ID/images 
directory are set correctly (or so I think...): oneadmin is the owner, 
and cloud is the group. Also the uid and gid are identical to the 
oneadmin user on my frontend. But the images/checkpoint directory seems 
to be owned by the root user, belonging to the root group.

Does anybody have an idea how this can be possible? Did I configure my 
cluster node in the wrong way?

Thank you,
Pieter
