Question 25: Is it possible to install and run more than one VM with MOSIX on the same node
Question 26: Can MOSIX run on an unmodified Linux kernel
Question 27: Why migrate processes when one can move a whole VM with a process inside

MOSIX2 - technical

Question 34: The latest release and change-log
Question 35: Technical support
Question 36: How to install
Question 37: After installing MOSIX in one node, how do I install it on the other nodes
Question 38: Why did the installer failed to patch my kernel
Question 39: Why did I get a kernel panic when trying to boot the MOSIX kernel
Question 40: After I installed MOSIX, "mosrun" produces "Not Super User" and exits
Question 41: May I mix different versions of MOSIX in the same cluster or multi-cluster.
Question 42: How can I see the state of my cluster or multi-cluster.
Question 43: Is it necessary to restart MOSIX in order to change the configuration
Question 44: How do I know that the process migration works
Question 45: What is the maximal number of multi-cores supported
Question 46: Is Hyper-threading supported
Question 47: What are the port numbers used by MOSIX
Question 48: What happens when a node crashes
Question 49: Does the traffic among MOSIX nodes pass safely through the IPSec tunnels
Question 50: Is it possible to run MOSIX over a WAN or the Internet

32-bit and 64-bit applications

Question 52: How do I inform MOSIX whether I use 32-bit or 64-bit systems
Question 53: Can I mix 32-bit and 64-bit nodes in the same cluster
Question 54: Can I run 32-bit programs on 64-bit nodes
Question 55: Can I run 64-bit programs on 32-bit nodes
Question 56: Can I have MOSIX running under a 64-bit kernel, but a 32-bit Linux installation, utilities and libraries (because it is so much easier to upgrade only the kernel)
