> When upgrading to 4.6 from 4.5 or earlier, the systemvm template that is registered upfront
is not marked as SYSTEM and set as the template for the existing systemvms. Therefore, new
systemvms work fine but existing ones don't.
> RCA is missing code in the upgrade path, as is present when upgrading from 4.4 to 4.5
for example.
> The code in the Upgrade442to450.java is not generic, as the name suggests, and simply
configures the whole SystemVM and all the existing Domain VMs to use the SystemVM-4.5.0 that
was registered. It means that after the upgrade all the routers were marked okay, but they
were using the old stuff, from 4.5.0. The attempt to deploy a new VM was also failing with
the following error (on the host):
> 2015-11-07 18:17:31,135 DEBUG [kvm.resource.LibvirtComputingResource] (agentRequest-Handler-4:null)
Exit value is 1
> 2015-11-07 18:17:31,135 DEBUG [kvm.resource.LibvirtComputingResource] (agentRequest-Handler-4:null)

> Why that? Because the KVM host has the new systemvm.iso, which contains all the new python
stuff, but the systemvm template, which installs the Guest OS (Debian) is old and does not
contain the modules we now need.
