QA:Testcase launch an instance on OpenStack
Launch an instance on OpenStack.
Optionally include information on preparing the test environment
How to test
Disable SELinux enforcing mode:
$> sudo setenforce 0 $> sudo sed -i 's/^SELINUX=enforcing/SELINUX=permissive/' /etc/selinux/config
Launch an instance of one of the images downloaded and registered in the previous test case.
$> cd ~/novacreds $> . ./novarc # note if the address of the host changes (like restarting a DHCP VM) you'll first need to edit this file $> euca-run-instances ami-tty --kernel aki-tty --ramdisk ari-tty -k nova_key
Verify that the instance has started.
$> euca-describe-instances RESERVATION r-d8wpvydq rbryant default INSTANCE i-00000001 ami-00000003 10.0.0.2 10.0.0.2 pending nova_key (rbryant, f16) 0 m1.small 2011-10-17T20:31:05Z nova aki-00000001 ari-00000002
It may take a while to transition from the pending to the running state, as reported by euca-describe-instances
$> sudo virsh list Id Name State ---------------------------------- 1 instance-00000001 running
Get console output and ensure instance is fully started
$> euca-get-console-output i-00000001
Try SSH-ing into the instance:
$> cd ~/novacreds $> ssh -i nova_key.priv -o UserKnownHostsFile=/dev/null email@example.com
Check for new errors in the logs:
$> grep -i error /var/log/nova/*.log
- 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
