[one-users] Cannot stop VM (OpenNebula 1.2)

[Ruben S. Montero]

Hi,

This turned to be a bit tricky, the final solution seems to be:

* Always use qemu://system, this is needed to bind a tap interfaces to
the bridge

* In order to have the right permissions a work-around is needed. This
is simple "touch" the checkpoint file before saving the VM. Take a
look at [1]

The revision [1] can be safely applied to the OpenNebula 1.4beta. If
your linux distro is connecting to qemu:///system. Just apply line 124
of /src/vmm_mad/kvm/one_vmm_kvm.rb

Cheers

Ruben
