Host VM goes unreachable after trove instance create

[Rajalakshmi Ganesan]

Description: Base VM on which trove is installed goes unreachable on DB instance creation.

Steps to reproduce:

1. Setup Devstack with trove enabled.
2. Create a trove instance using the following command:
venkater@devstack-trove:~/devstack$ trove create ps_test 2 --size 1
+-------------------+--------------------------------------+
| Property | Value |
+-------------------+--------------------------------------+
| created | 2014-07-02T13:06:51 |
| datastore | mysql |
| datastore_version | 5.5 |
| flavor | 2 |
| id | b09b94fe-0dd6-47bf-966a-e66af4a019cf |
| name | ps_test |
| status | BUILD |
| updated | 2014-07-02T13:06:51 |
| volume | 1 |
+-------------------+--------------------------------------+
venkater@devstack-trove:~/devstack$
3. Wait for a while (about 10 seconds) and then ping the host VM on which trove was installed.

Expected Result:
The host VM should be reachable and we must be able to list the trove instance.

Actual Result:
The host VM becomes unreachable and we are unable to ping/ssh into the VM.

Please find the attached log of trove manager. (tr-tmgr)

Using your setup, are you able to launch a nova instance and then ssh into it?

Hi Rajalakshmi:
Can you add the trove public key (can be found at https://github.com/openstack/trove-integration/blob/master/scripts/files/keys/authorized_keys) to the ~/.ssh/authorized_keys, and try again?

Thanks,
Nikhil

Hi Amrith,

No I am not able to launch a nova instance also. The VM goes unreachable even on launching a nova instance.

Hi Nikhil,

Yes I added the public key you mentioned and tried to boot trove instance again. But still the VM goes unreachable after "trove create" command.

Hi Rajalakshmi:

If you are unable to boot a nova instance, the issue isn't with trove. Trove depends on nova.

So, for debugging purposes, it would be best to first understand why nova won't launch an instance.

What do you see when you run these three commands?

nova list
nova flavor-list
glance image-list

It looks like your actual eth0 IP is part of the FIXED_IP range that is being used in devstack. This seems like a networking misconfiguration. Please use a different FIXED_IP range for your devstack install.
