# OpenVZ and DevStack - instances not starting

Hi,

I have been trying to get nova working with OpenVZ using the driver available at [0]. I am using a Debian 7 host with an OpenVZ 2.6.32 kernel that joyfully runs OpenVZ guests (probed it using using the vzctl tool). However, the nova-compute service fails, erroring "unable to load the virtualization driver".

For deployment I used the havana branch from devstack and tweaked the nova.conf to use compute_driver=openvz. Are there more updates that should be brought to the environment in order to enforce the use of OpenVZ? Localrc file below.

Thanks, Ana
