There are several commands that help in managing the instances. Here are a few examples:
$ euca-run-instances ami-00000003 -k mykey -t m1.tiny RESERVATION r-f1ek1ojb proj default INSTANCE i-00000005 ami-00000003 pending mykey (proj, None) 0 m1.tiny 2011-10-19T12:48:04Z unknown zone ami-00000000 ami-00000000

$ euca-reboot-instances i-00000005
$ euca-terminate-instances i-00000005
$ euca-run-instances ami-XXXXXXXX -k mykey
$ euca-get-console-output i-00000005 i-00000005 2011-10-07T07:22:40.795Z [ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Linux version 2.6.32-21-server (buildd@yellow) (gcc version 4. 4.3 (Ubuntu 4.4.3-4ubuntu5) ) #32-Ubuntu SMP Fri Oct 07 09:17:34 UTC 2011 (Ub untu 2.6.32-21.32-server 2.6.32.11+drm33.2) .............
You can make password less ssh access to the instance as follows:
ssh -i mykey.priv user@192.168.4.3
VM type has implications for harddisk size, amount of RAM and number of CPUs allocated to the instance. Check the VM types available.
sudo nova-manage instance_type list
