Re: [openstack-dev] [devstack] image create mysql error
Hi, Looks like the password supplied wasn't correct. Have you changed the pasword given in local.conf after a devstack installation? If yes, you need to purge mysql credentials stores in your machine.

Re: [openstack-dev] [nova] nova host-update gives error 'Virt driver does not implement host disabled status'
Thanks Vladik for the reply. Jay Lau directed me to your patch. But what I don't get is.. Shouldn't NotImplementedException be removed? I mean, if other drivers are implementing set_host_enabled method, shouldn't libvirt also implement the same?

Hi Anna, Sorry not to be more verbose. Your suggestion works fine in a non-cell devstack installation. But as soon as I have 'ENABLED_SERVICE+=n-cell' in local.conf of devstack, things start to fail. Where as I'm able to boot a server on my own with nova boot command, tempest fails miserably with error 'no host found'. Thanks for that suggestion.

[openstack-dev] Multi host devstack
Hi, Has anyone successfully installed devstack as multi-node setup using this tutorial? http://docs.openstack.org/developer/devstack/guides/multinode-lab.html I'm unable to do so.

Hi Andrew, Since you have mentioned one approach to solve the flavor meta data to driver.spawn. I want to draw your attention to this code review thread as well, https://review.openstack.org/#/c/108238/. I didn't want to edit your etherpad notes, hence this email.

What are the use cases for this deployment? Agreeably, root node runs n-api along with horizon, key management etc. What components are deployed in tier 2 and tier 3? And AFAIK, currently, openstack cell deployment isn't even a tree but DAG since, one cell can have multiple parents.
