[one-users] Problem with shared_lvm driver

[Carlos Martín Sánchez]

Hi,

When the VM is running, onevm delete and onevm cancel perform the same
driver operations, but with cancel OpenNebula waits for the VMM driver
success before deleting the disks.

onevm delete is more like a last resort to remove the VM from OpenNebula in
case of error. The VM is removed immediately and OpenNebula tries to clean
up, but the right way to destroy a VM is onevm cancel.

In 4.0 we have synchronized the onevm delete driver operations, but the VM
is still removed immediately and if the cleanup fails it is not checked.

Regards
