I'm in the process of getting Nova/Glance running within a DomU instance. When I attempt to build a VM, the nova-compute worker crashes while it attempts to write the partition table.
It looks like the DomU compute instance doesn't have a device /dev/xvdb. Here are the relevant parts of the (massive) traceback: http://paste.openstack.org/show/532/ <http://paste.openstack.org/show/532/>Any ideas? -Rick ________________________________ From: openstack-xenapi-bounces+rick.harris=rackspace....@lists.launchpad.net [openstack-xenapi-bounces+rick.harris=rackspace....@lists.launchpad.net] on behalf of Ewan Mellor [ewan.mel...@eu.citrix.com] Sent: Wednesday, January 19, 2011 2:33 PM To: Sandy Walsh; openstack-xenapi@lists.launchpad.net Subject: Re: [Openstack-xenapi] Glance / Nova - Compute required on Dom0? Cool, so are you OK with running it like this? We were debating here whether we’d need to add a flag for a developers’ mode, but that would involve duplicating lots of code, so I’d rather not. When we’re working on nova-compute, we’re NFS-mounting the nova source repo from our dev boxes into a test VM. That way, we can switch branches at will, and leave the VM running, and so we don’t need to keep redeploying nova just to test it. Cheers, Ewan.

Thanks, Andy informed me of this assumption. I was running it on a separate machine. Good to know that /sys/... is available on all Linux VM's. Don't suppose anyone has created any deploy scripts to make this process easier? Between getting compute on a DomU and installing the plugins, it's getting tricky to jump between development branches.

There’s an assumption that nova-compute either runs in dom0, or on a VM on the host that it’s managing. In either case, there should be /sys/hypervisor/uuid available. Where are you running it? Ewan.

Hi guys, With the merge of xenapi-glance-2 into trunk I'm running into a few problems. I can get the images successfully into/out of Glance now, but when starting the instance I'm hitting http://paste.openstack.org/show/495/ The missing file exists on Dom0, but, is there an assumption here that Compute runs on Dom0? Currently I'm running it separately. Is the no way to get this value via XenAPI? (I've been trying all morning, but can't see to get it) If we don't want to run Compute on Dom0 should I extend the plugin to do this query remotely?
