Some systems have to have a strict control, even in system state
information. Prefixed with "sudo" to command to gather information how
cloud init is doing.
There were very similar methods for downloading/proceeding with
checksum for both Ubuntu and Fedora classes. Extracted those two into
methods in base class.
For now, the only mode VirtualBox VM has launched was headless. For
debugging purposes, there were other types allowed using --type switch
for command create and rebuild, while headless will remain the default
one.
Currently, you could pass long version of '--version' option to either
boxpy itself and subcommands create and rebuild. With this patch proper
context is now detected.
Till now, boxpy was based on the fact, that there was power_state
section, and there was a check if VM is down already. That approach have
their own issues.
Now, there will be no more power-off, there is a check by using
`cloud-init status` command through ssh.
Cleanup/destroy parts has needed some modification, so that there will
be no leftovers from cloud init ISO image.
And finally, there was some tweaks for user-data cloud-init part (mainly
for ssh handling), so that `cloud-init status` will not report phony
errors.
If user doesn't provide options from commandline during rebuild, such
option will be overwritten by those stored in VM XML, even if user
change such option in config file. This commit fixing that.
Till now, user has to provide port number (by commandline or through
config file), otherwise 2222 will be set. That's unfortunate in case you
need to have multiple machines and forgot about setting the correct
port. In this patch random port will be used if no port is provided.
