I installed nova on a single node, and when i want to launch a instance I got : Instance '11' failed to spawn. Is virtualization enabled in the BIOS? But VT extensions are enable in the bios and I can launch a VM manually with KVM.

Thank you for your help.

I have been using the --glance_api_servers flag. There were some zero sized items in _base, so I nuked them all.
Yet when I try to create an instance I still get the same problem (a zero sized item gets created in _base and no kernel file appears at all). I think the problem is with glance. I am seeing this in the glance log:

do you have the same version of blance on both machines? dpkg -l | grep glance

I solve the first error with enabeling nbd, but I get a new error :

I think it failed to download kernel to /var/lib/nova/instances/instance-00000000e/kernel. Please check whether the file exists and the size of the file is correct.

the file exists but it's empty.

I am seeing this same problem (zero sized kernel). This works on one compute node but not on a second node. I am using Glance as my image store. Has anybody identified a root cause for this?

Generally it is due to missing settings for glance or wrong versions --glance_api_servers=host:port needs to be set or it will default to localhost and it will only get images on the machine that is running glance. You should also clear out the 0 sized images in _base

There is only once glance server (and two compute nodes). But the python-glance package on the compute nodes is different:

Node that works has: ii python-glance 2011.3~d1~20110531.139-0ubuntu0ppa1~natty1 Node that does not work has: ii python-glance 2011.3-d2-hp1

I'll run this one to ground and post an update (probably monday).
