Description
Launch an instance on OpenStack.
Setup
Optionally include information on preparing the test environment
How to test
Launch an instance of one of the images downloaded and registered in the previous test case.
$> . ./keystonerc
$> nova boot --image $(nova image-list | grep ami-tty | awk '{print $2}') --flavor 1 --key_name nova_key testvm
Expected Results
Verify that the instance has started.
$> nova list +--------------------------------------+----------+--------+------------------+ | ID | Name | Status | Networks | +--------------------------------------+----------+--------+------------------+ | a47a424a-014b-4b81-97e6-b34d31b5589d | Server 1 | ACTIVE | testnet=10.0.0.2 | +--------------------------------------+----------+--------+------------------+
It may take a while to transition from the BUILD to the ACTIVE state, as reported by 'nova list'.
If the instance goes into the ERROR state, then check the nova-compute logs for errors:
$> grep ERROR /var/log/nova/compute.log
What might help is to restart the nova scheduler with 'sudo systemctl restart openstack-nova-scheduler.service' and try again in case the scheduler reports an error in the logs.
Confirm the VM running with virsh:
$> sudo virsh list Id Name State ---------------------------------- 1 instance-00000001 running
Get console output and ensure instance is fully started
$> nova console-log --length 100 <instanceid>
Try SSH-ing into the instance:
$> ssh -i nova_key.priv -o UserKnownHostsFile=/dev/null root@10.0.0.2
Check for new errors in the logs:
$> grep -i error /var/log/nova/*.log
Notes:
- We use
/dev/nullfor known hosts because the fingerprints associated with these IPs will change when you start over with your testing; updating known hosts gets annoying - You've probably got a stale dnsmasq process around if you see:
dnsmasq: failed to create listening socket for 10.0.0.1: Address already in use
