    Added the following not to the file and will push it to the PR:
    
    #
    # IMPORTANT REMARK
    # Package intallation is no longer done via this script. We are not removing the code
yet, but we want to 
    # make sure that everybody willing to install/update packages should refer to the file:
    #   ==> cloud-tools/appliance/definitions/systemvmtemplate/install_systemvm_packages.sh
    #
    
    Is it good enough?
    
    Cheers,

>             Project: CloudStack
>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: Virtual Router
>    Affects Versions: 4.6.0

> There is an intermittent problem with the keepalived on the redundant VPC routers. Sometimes
both routers stay on Master state for a while.
> We are able to reproduce it only when testing with Marvin, which executes the calls very
quick. When using the UI and following the same steps, it doesn't happen.
> Setting up:
> 1. Create a VPC using redundant VPC offering
> 2. Add 2 Tiers
> 3. Create 2 VMs in each Tier
> 4. Create ACLs to allow traffic on port 22 coming from 0.0.0.0/0
> 5. Acquire 4 public IPs
> 6. Create Port Forwarding rules - per IP - for port 22
> 7. Assign each PF created to one of the VMs
> 8. SSH to the VMs
> Testing fail over:
> 1. Stop the Master Router
> 2. Check the the Backup Router became Master
> 3. SSH to the VMs 
> Testing failure:
> 1. Delete all port forwarding rules
> 2. SSH to the VMs 
> 3. Verify that it no longer works
> Test recovering
> 1. Restart the router
> 2. Once the router is running, check that it's on Backup state
> 3. Add the port forwarding rules back
> 4. Verify that the routers are still on the same state: 1 Master and 1 Backup
>     - That's the part when it fails during the Marvin tests
>     - When 2 routers are on Master, by restarting 1 router will bring everything to a
normal state: 1 master and 1 backup
> 5. SSH to the VMs
