So far i've setup 2 compute nodes and 1 controller node. They all share the /var/lib/nova/instances dir. I've already verified that the nova user id is the same across all the servers. Currently i'm running into this error when i launch an instance: http://paste.openstack.org/show/19221/ It's certainly a permission issue, so i tried adding the group "nova" to the user "libvirt-qemu". However, it still doesn't work. To which user must i give the nova group permission in order to be able to write in that directory?
