Apologies if this is the wrong place to post this question. In that event, please point me in the right direction. My question is whether or not I can use Xen with OpenMosix. The upshot of what I''m attempting to do is this: 1. Build a two to four node cluster using OpenMosix for "raw horsepower" 2. Use Xen on the OpenMosix cluster to divide the "raw horsepower" any way that I need it I am specifically interested in setting up two or more Xen Domains for full desktop utilization over VNC with Fedora Core 3. I would then use the rest of the system for various internal servers: DNS, HTTP, DHCP, Icecast (streaming media), MySQL, and the like. The main goals in clustering + paravirtualization would be: a. High availability (HA) b. HA and session portability for the desktop domains (using the -live option) c. High performance compute power (thanks to clustering) However, seeing that both OpenMosix and Xen modify the host kernel, I am not certain that this will work at the host system level. I''m also not sure if using multiple Xen systems and attempting to cluster the Xen guest systems would work either. Any info I can get regarding this will also help me make a decision on how I will upgrade my current system (a standard SMP PII 450 system running Redhat 9 for desktop via VNC). I am currently thinking of setting up a cluster of two to four AMD Athlon 64 systems. But, if clustering won''t work, I might consider a two way Opteron system once those become more readily available.

Re: [Xen-devel] New to Xen: Can Xen Work with OpenMosix?
not quite the same thing, but I just recently got the xen to run with clustermatic (http://www.clustermatic.org/), using bproc.

Start reading now. > http://ads.osdn.com/?ad_id=6595&alloc_id=14396&op=clickWhat you''re trying to do won''t work, since OpenMosix doesn''t really support a computing model where any process can be migrated. It primarily migrages computational context of a process, while the system calls stay put. Xen is way too special of a way process, mostly system calls, to be migrated by OpenMosix. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
