What does it mean 'not responsive'? You can't ping it?

Is there anything unusual in Nova logs (nova-api, nova-compute)?

2016-07-15 02:02:13 -0500 answered a question Total usable vcpus: 72, but GUI says 20


That is because your default vCPUs quota. It can be configured in OpenStack Dashboard:

Admin -> System -> Defaults -> Update Defaults-button

There will be the vCPU textbox in the table. Change this value.

2016-06-29 02:28:57 -0500 answered a question Where is the image/snapshot stored?

Completed snapshot files are located /var/lib/glance/images/ on controller node. The file names are UUIDs of glance images, you can check via glance image-list-command.

This is useful if you want to migrate snapshot to another host. After migrating snapshot file you may add it to your glance images via glance image-create-command.

Hope this helps. Good luck.

IMHO, VNC through browser is very slow itself, but sometimes it depends on hypervisor you use. KVM VMs work faster, than QEMU. What hypervisor do you use?

2015-12-21 12:16:30 -0500 answered a question nova-novncproxy.log - gaierror: [Errno -8] Servname not supported for ai_socktype

I had the same trouble.

As I can see from logs, novnc tried to connect to the server with a negative port value: connecting to:

My solution was to check VMs status (it was SHUTDOWN), so after nova start VM, port in vnc got normal positive value.

Hope that helps.
