There are several commands that help in managing the instances. Here are a few examples:
$ euca-run-instances emi-721D0EBA -k mykey -t c1.medium RESERVATION r-55560977 admin admin-default INSTANCE i-50630A2A emi-721D0EBA 0.0.0.0 0.0.0.0 pending mykey 2010-05-07T07:17:48.23Z eki-675412F5 eri-A1E113E0 $ euca-describe-instances RESERVATION r-55560977 admin default INSTANCE i-50630A2A emi-721D0EBA 192.168.3.130 192.168.3.130 running mykey 0 c1.medium 2010-05-07T07:17:48.23Z myueccluster eki-675412F5 eri-A1E113E0 $ euca-reboot-instances i-50630A2A $ euca-terminate-instances i-50630A2A $ euca-run-instances ami-XXXXXXXX -k mykey $ euca-get-console-output i-50630A2A i-50630A2A 2010-05-07T07:22:40.795Z [ 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 Apr 16 09:17:34 UTC 2010 (Ub untu 2.6.32-21.32-server 2.6.32.11+drm33.2) [ 0.000000] Command line: root=/dev/sda1 console=ttyS0 [ 0.000000] KERNEL supported cpus: [ 0.000000] Intel GenuineIntel [ 0.000000] AMD AuthenticAMD [ 0.000000] Centaur CentaurHauls [ 0.000000] BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: 0000000000000000 - 000000000009f000 (usable) [ 0.000000] BIOS-e820: 000000000009f000 - 00000000000a0000 (reserved) .............
You can make password less ssh access to the instance as follows:
ssh -i mykey.priv user@192.168.3.130
Make sure that you launch the instance with the correct VM type. If it is launched with a smaller VM type,then the following error is encountered.
error: insufficient disk capacity remaining
By default, m1.small is the VM type that is used which comes with a 2GB Hard Disk. So if you have a disk image of size 5GB, instead of
euca-run-instances ami-XXXXXXXX -k mykey
use
euca-run-instances ami-XXXXXXXX -k mykey -t c1.medium
VM type also has implications for amount of RAM and number of CPUs allocated to the instance.
Check the VM types available.
sudo nova-manage instance_type list
