I have not set up a guest linux yet, but I experienced a problem with Win98 guest which may sound related: I start the guest win98 and try to open a dos-window. The window opens but no output is presented (no prompt, no nothing) and guest system somehow "hangs". Sometimes (rarely) I can make it work again by hitting keys on the keyboard. The effect started off as window coming up with prompt, I tried to ping the host system, and the first packet was somehow slow, but then everything was ok. On the next guest boot, some output appeared at the dosbox, but the prompt was delayed. Now I get no prompt no matter what I try. Host system is 2.4.18-pre7. Vmware was installed from scratch, win98 guest was installed from scratch with no additions whatsoever. ping from host to guest works flawlessly. > If I ping from the "host" linux console to the "guest" linux system, > responses came back, and does not hang. I'll double check this last point. > Got to recompile the kernel again. As I never saw this with vmware 2 (even not on 2.4.18-pre7) I would say version 3 has a real problem somewhere.
