I disabled firewall, created a network bridge on the host(MAC Bridge Miniport) 169.254.193.127 host Win-7 169.254.162.162, gues Sol-10 169.254.163.163, mask 255.255.0.0, OS's are 64 bits. In VBox network is set to Bridged. I google many many articles, no aswers. After this connection is made I whant to install Oracle 11g on Solaris gues. This will require file sharing. Badly need help. Thank you in advance.
Use Host only adapter mode. It's the simplest one for network sharing. Make both computers to same workgroup.
Note : For bridged mode you need a router.
