multi node instance failure

Asked by nimda on 2011-03-30

Hi,

  I've 6 machines I want to run OpenStack on. I'm planning on one controller, and the rest nodes.

I've configured the controller to run instances locally, using ubuntu1010-UEC-localuser-image.tar.gz, and I'm able to ping and SSH to them, etc. Yay :D The joy.

I then add a compute node. I'm manually installing parts to get a feel for what's happening. Here's what I do:-

$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:nova-core/trunk
$ sudo apt-get update
$ sudo apt-get install -y nova-common nova-compute python-mysqldb python-suds vlan

I'll then scp nova.conf from the controller to the node, and restart all services on all machines, after nova-manage db sync on the controller. I don't edit network/interfaces for br100 as I'm running VlanManager, this could be a mistake. The node will then appear in the services table.

When I attempt to run instances, and when they're scheduled for on the additional nodes the instances always fail. Here are 2 log files, from 2 nodes I've tried to configure:-

There are error messages about virtualization not being enabled in the BIOS, but this is not the case, it is enabled.

Any ideas?
