[ec2] Cannot reboot instances

[Darren Govoni]

Eric,
   I did not know that! I use command line reboot all the time and of
course, its blazing fast on the 64-bit high-end machines, but I guess I
never tried from ec2 console until now and noticed the rather odd
behavior where it changes to "rebooting" with blue icon, but after
refresh goes back to green. I will double check that it actually does
reboot though...

Thanks again for the help!

Darren
