Thread: [SSI-users] openssi and virtual machine

Has anyone been able to set up VM software to run on an openssi cluster to
make all the resources of the cluster available to the VM software?

You mean, some VM software running in openssi as host system, where the
guests can use all the ressources of the whole cluster?

I never tried that, but I think, the main problem would be, if you want
to run a guest as a virtual multiprocessor system, and run the processes
inside the guest on different hosts of the cluster. I guess, that this
is not possible at the moment (because threads have to run on one
clusternode).
On the other side, running one virtual machine on one clusternode
shouldn't be a big problem. I hope.

Nevertheless, a good idea to try that.

Treating an OpenSSI cluster as a big NUMA machine shouldn't be _that_ difficult, but certainly not a walk in the park. Getting OpenSSI smooshed into any modern kernel would still be necessary, though. A stable target like RHEL/CentOS 5 is a good idea, but who has the time these days? :P

I think the answer depends on the technology.  One thing that hasn't
been explored yet is integrating OpenVZ into OpenSSI so that each
instance can form their own virtual OpenSSI cluster.
