The 128 / 256 bit seems to indicate the "Native SIMD architecture width available at runtime." of the host, which I assume references your graphics card. Do you have different gpus in the two host systems?

[Tobias Fromm]

Yes, unfortunately we have different GPUs all over the place.
However, we've given up on this issue and now simply run a dedicated server for the simserv VMs; there, the issue doesn't occur. Also, regarding available computing power this is the better solution anyways. So I'm sorry I can't give a real solution on the GL-vs-VM problem, we've now simply worked around it and everything runs as expected.

We have just posted a topic which explains how to setup a native simulator and a simclient virtual machine (VM). This might be a viable workaround for Problems which arise by running the simsrv VM:

we managed to reproduce these "Illegal Instruction" errors and on one of our test system we found the solution to be to enable the virtualization features in the BIOS of the host-computer - see http://euroc.iphpbb3.com/forum/viewtopic.php?nxu=20112706nx57588&f=4&p=372#p372
