SSH connection to a Virtual Machine from a Non-Host machine on the same LAN

[Philip Rhoades]

People,

 From machine B (10.1.1.14) I can ssh to machine A (10.1.1.10) that 
hosts a Virtual Machine (192.168.122.216) and from there I can ssh to 
the VM.  However it would be nice if I could ssh directly from B to the 
VM.  I have set up a static route on the router (10.1.1.1) to send 
traffic for 192.168.122.x to 10.1.1.10 but I presume I need to also set 
up a rule with iptables on A? - I can use tcpdump to see that the ssh 
request does make it to A but the request is refused.

Thanks,

Phil.

To answer my own question - I found this "hack" that at least works:

It's going to be far simpler to set up a shared physical device.

I can't get to the libvirt wiki right now, but I think the right page
is:
