Yes of course. Sorry, I forgot this in my description above.

The host Linux sees all this memory. We plan to expand this to 16 GB and run 4 guests with a legacy 32-bit OS. Is it possible that these guest see 3 GB or is there still a 2 GB limit for 32-bit guests on 32- bit hosts? I searched a lot about this topic in this mailing list, but I'm not quite sure. Unfortunately we currently need to use several hosts with CPUs that don't support 64-bit. So I got the idea to use the PAE Linux on these hosts. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
