[one-users] Cannot create a VM snapshot

[Pavel Tankov]

The 'snapshot_create' script is not available on /var/tmp/one/vmm/kvm/. 
The contents of this folder is:

# ls -l /var/tmp/one/vmm/kvm/
total 32
-rwxr-xr-x 1 oneadmin oneadmin  1596 Aug 20 11:25 cancel
-rwxr-xr-x 1 oneadmin oneadmin  1545 Aug 20 11:25 deploy
-rw-r--r-- 1 oneadmin oneadmin  1790 Aug 20 11:25 kvmrc
-rwxr-xr-x 1 oneadmin oneadmin 14255 Aug 20 11:25 poll
-rwxr-xr-x 1 oneadmin oneadmin  2304 Aug 20 11:25 shutdown

But isn't this a temporary folder. Is the script expected to be there?

On the other hand:

# find / -name snapshot_create
/var/lib/one/remotes/vmm/sl/snapshot_create
/var/lib/one/remotes/vmm/ec2/snapshot_create
/var/lib/one/remotes/vmm/kvm/snapshot_create
/var/lib/one/remotes/vmm/vmware/snapshot_create
/var/lib/one/remotes/vmm/az/snapshot_create
/var/lib/one/remotes/vmm/xen3/snapshot_create
/var/lib/one/remotes/vmm/xen4/snapshot_create
