CLOUDSTACK-1410: Add the old constructor to VirtualMachineTO
Although the code compiled just fine, add back the old constructor
for safety.
> Overcommit feature breaks compatibility between 4.0/4.1 management server and
> 4.2 agent

> Key: CLOUDSTACK-1410
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1410
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: KVM, Management Server
> Affects Versions: 4.1.0, 4.2.0
> Environment: Ubuntu 12.04. 4.0 management server, 4.2 agent
> Reporter: Wido den Hollander
> Assignee: Bharat Kumar
> Fix For: 4.2.0
>
>
> I just updated one of my agents to the 4.2 (master) code and it failed to
> start the new instance.
> I got a NullPointerException on this piece of code in
> LibvirtComputingResource:
> ctd.setShares(vmTO.getCpus() * vmTO.getMinSpeed());
> getMinSpeed() is new, this used to be getSpeed()
> The VirtualMachineTO was however changed and getSpeed() was removed.
> A 4.0/4.1 management server however sends only the "speed" value instead of
> "minSpeed" and "maxSpeed".
> This leads to a 4.2 agent not working with 4.0 or 4.1 code.
> A couple of suggestions:
> - Add getSpeed() (and int speed) back to VirtualMachineTO
> - Check if getMinSpeed is empty and fall back to getSpeed if it's NULL
> Would that be a acceptable solution?
