It is quite insecure. what's about put the tenant into trove tenant?While the default configuration of Trove in devstack puts Trove guest VMs into the users' respective tenants, it's possible to configure Trove to create VMs in a single "Trove" tenant. You would do this by overriding the default novaclient class in Trove's remote.py with one that creates all Trove VMs in a particular tenant whose user credentials you will need to supply. In fact, most production instances of Trove do something like this.Might I suggest that if this is how people regularly deploy, that such a class be included in trove proper, and that a config option be provided like "use_tenant='name_of_tenant_to_use'" that would trigger the use of the overridden novaclient class? I think asking an operator as a standard practice to override code in remote.py is a bad pattern.2) Why there is no trove mgmt cli, but mgmt api is in the code? Does it disappear forever ?The reason for this is because the old legacy Trove client was rewritten to be in line with the rest of the openstack clients. The new client has bindings for the management API, but we didn't complete the work on writing the shell pieces for it. There is currently an effort to support Trove calls in the openstackclient, and we're looking to support the management client calls as part of this as well. If this is something that you're passionate about, we sure could use help landing this in Liberty.3) The trove-guest-agent is in vm. it is connected by taskmanager by rabbitmq. We designed it. But is there some prectise to do this? how to make the vm be connected in vm-network and management network?Most deployments of Trove that I am familiar with set up a separate RabbitMQ server in cloud that is used by Trove. It is not recommended to use the same infrastructure RabbitMQ server for Trove for security reasons. Also most deployments of Trove set up a private (neutron) network that the RabbitMQ server and guests are connected to, and all RPC messages are sent over this network.This sounds like a great chunk of information to potentially go into deployer docs.I'd like to +1 this. It is misleading that the standard documentation (and the devstack setup) describes a configuration that is unsafe/unwise to use in production. This is surely unusual to say the least! Normally when test or dev setups use unsafe configurations the relevant docs clearly state this - and describe how it should actually be done. In addition the fact that several extended question threads were required to extract this vital information is ...disappointing, and does not display the right spirit for an open source project in my opinion!
While I agree with this last paragraph....
i really want to vote to put trove back into stackforge for it can not give an clear deployment,
... I must point out this is *NOT* the way this community (OpenStack) works. This mailing list exists to discuss things in the open, make sure we can have wide and constructive discussions to make things like the ones discussed in this thread come out so that they can be improved, documented and made public for the sake of usability, operation and adoption.
and it is always avoiding problem, not to face it. The service vm need get connect through the management should talk about a lot.
It's now on Trove team's - or other people's - hands to help find/implement a better solution for the problem pointed out in this thread and make the product better. Let's collaborate, Flavio
