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

[Pieter Simoens]

Dear all,

following up on my e-mail below: according to 
http://dev.opennebula.org/issues/131, this should be solved in my 
version (I am running 2.0).

It seems it has to do with the way you connect to the virsh socket 
(qemu:///system ?)

So, I think the question is: where is the variable $LIBVIRT_URI 
specified? At least, that is the variable that is used in the 
/var/remotes/vmm/kvm/save script?

Best regards,
Pieter
