[one-users] ONE 3.2 VM Management issues

Thu Jan 26 06:33:56 PST 2012

Hi,

Your 1st problem might be related to the qemu dynamic_ownership
configuration, check the kvm configuration guide [1] for more details.

About the automatic IP assignment, you need to contextualize your VMs so
they can configure the IP leased by OpenNebula, see [2] for more
information.

Regards.
