Of course. It's effectively a standalone machine. Running on some curious hardware..

Since you specifically mentioned vmware, you might try something like: vmware.for-linux.general.

Okay. Another possible thought is disabling the internet support in the guest OS. But that would be blocking the applications that are running on the guest OS to access internet. :-( > > From the point of view of the guest os, it's as if it > had it's own real network interface card, so it's just > as susceptible to network attacks, as it would be if > running on native hardware. > > As with any m$ software, make sure it's protected by > a properly configured router. > Okay, but it is strange that there is no mechanism/tricks in VirtualBox/Vmware to make the packets to flow through the host OS to the guest OS ? > > If Windows crashes, is there a mechanism > > to recover it from Host OS(Linux) ? > > It works the same as it would, when running on native > hardware.

Need to check the mechanism to pass the traffic through the host OS(Linux) to guest OS (bridge networking) and the virtual network card to force internet traffic through iptables in VirtualBox / Vmware. > > > If Windows crashes, is there a mechanism > > to recover it from Host OS(Linux) ? > > Also, is there any mechanism to debug windows > > from linux ?
