If you are interested, I have a patch for keepalived which allows it to use unicast between a local and a remote VIP. I've successfully been using it at vps.net between virtual machines.
It's a lot simpler than trying to set up a tunnel ! I've uploaded it there :
http://1wt.eu/keepalived/
You then just have to specify "vrrp_unicast_bind " and "vrrp_unicast_peer ". It will still use the VRRP protocol, but only between those IPs.
Hoping this helps !
Don't use a password. Generate a passphrase-less SSH key and push it to your VM.
If you already have an SSH key, you can skip this step…
Just hit Enter for the key and both passphrases:
$ ssh-keygen -t rsa -b 2048
Generating public/private rsa key pair.
Enter file in which to save the key (/home/username/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/username/.ssh/id_rsa.
Your public key has been saved in /home/username/.ssh/id_rsa.pub.
Copy your keys to the target server:
$ ssh-copy-id id@server
id@server's password:
Now try logging into the machine, with ssh 'id@server', and check-in:
.ssh/authorized_keys
Note: If you don't have .ssh dir and authorized_keys file, you need to create it first
to make sure we haven’t added extra keys that you weren’t expecting.
Finally, check to log in…
$ ssh id@server
id@server:~$
You may also want to look into using ssh-agent if you want to try keeping your keys protected with a passphrase.

In order to route multicast traffic, you need a userspace daemon like
smcrouted(recommended) ormrouted.Since you'll also be needing some kind of interface representing the destination network in the routing table, you could create tunnel interfaces for your SSH connection using the
ssh -w 0:0. This will create an interfacetun0on both your SSH hosts.
