If I understand your problem correctly, you want to ping your computer from another computer. The ping 1.2.3.4 works but the ping hostname doesn't. What I suspect the situation being is that your computer doesn't have a its hostname registered in DNS that is discoverable by the other machine.

I am guessing you don't have your own DNS server. Computers understand IP addresses but not the name of your computer. To make it so, you need to either add a record in your hosts file, which can be found in /etc/hosts, or have a DNS entry on your DNS server. Then it will know what you mean by the hostname of your machine.

The current version of IP has "zeroconf" addresses built in. If IPv6 is enabled, in general there should be a link-local address. You can't scan for it as IPv6 addresses are too large. You should be able to watch for automatic addresses when you turn the device on, as its kernel will probe to make sure no other device has the same address. You can use ...

Have a look at the routing table of the 'Physical' PC and see how traffic to these networks are routed. If that host is only 'equipped' with a default route you need to use that address to add your static routes on the guest. For example, the 'physical' host has only a static route of 145.17.1.1: route add -net 145.17.0.0/16 gw 145.17.1.1 route add -net ...
