Re: [Openstack] [OpenStack][Nova] Live Migration Error
I see pre_live_migration in destination compute log, so migration at
least started.
Since there are no errors in either compute log, is it possible that
migration is taking long ? (Just a possibility)
When you say migration fails what error did you get ?

The migration still fails, but i see no errors in the logs. I'm trying to
migrate a VM with the m1.tiny flavor from one machine to another. Their
hardware are identical and they have more than enough resources to support
the m1.tiny flavor:
cloud35 (total) 43867 186
cloud35 (used_now) 0 312 5
cloud35 (used_max) 0 0 0
These are the logs from the origin compute node:
http://paste.openstack.org/show/19319/ and the destination compute
node: http://paste.openstack.org/show/19318/ . The scheduler's log has no
visible errors or stack traces.
I'm still using nfsv4.
Any ideas?

It looks like you are using distribution package rather than devstack
installation, so it is likely that the issue is now fixed. Can you try
latest packages (and/or try devstack if you can)

Re: [Openstack] 答复: [OpenStack][Nova] Live Migration + NFSv4 - Permission issues
So i've managed to get my instances to launch, thx Mandar! Does that mean you used nfsv3 ? Based on the comments on the URL, several people (all ??) seems to have problem with nfsv4 *Anne, Is it possible to add this to FAQ (or relevant document(s) )? *(after Leander confirms that nfs v3 solved the problem) (See https://answers.launchpad.net/nova/+question/164689, specifically comment #11) -Mandar ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

[Openstack] 401 Not Authorized from glance - How to fix ?
Hi, I'm working on python program that needs to get images detail from glance. I was using get_admin_context earlier to do all the work in nova side, but this doesn't seem to work when I query glance. I get 401 Not Authorized error. I think I need to get auth_token from keystone, and use it when creating RequestContext object - then glance query might work. (Is this assumption correct, in the first place) But I do not know how to do this programatically, I looked at nova image-list command, but I didn't get clear picture on how this should be done. Can you point to any existing code that authenticates with keystone and then uses the auth-token to talk to glance ?
