Hi all,

I installed Oracle virtual box 4.1.8 on my desktop. I installed Windows 2008 server R2 as one instance and Solaris 10 as another instance. When am trying to ping from Windows to solaris and vice-versa, ping not working.

windows IP : 10.1.47.24
Solaris IP : 10.1.47.25
 
netstat -nr output from solaris
 
Routing Table: IPv4
  Destination           Gateway           Flags  Ref     Use     Interface

Windows often doesn't bother answering ping these days, so one half of that isn't really abnormal.

I once tried to make a network of 4 Ubuntu machines and I couldn't get them to ping each other "as is". I had to set up VirtualBox to actually create a dhcp server for the devices, after which they could ping each other (And their ip addresses changed as well too) and Then I could do whatever networking I wanted between the devices.

Google for "vboxmanage to create network". You should be able to find links which suggest a command like this one:

VBoxManage dhcpserver add --netname intnet --ip 192.168.59.1 \     --netmask 255.255.255.0 --lowerip 192.168.59.2 --upperip 192.168.59.255
