Re: Run RTLinux in a VM?

[Vivek Ayer <vivek.ayer@gmail.com>]

Hi all,

Thanks for the quick responses. I'm not so concerned about the ill
effects of rt performance right this moment. I will probably get a
physical machine for it in two months or so. The main reason now is to
just get quick started on rt programming per say. My host machine is a
client written in PyQt that will be interfacing with RTLinux machine
and I just wanted to test a couple of things before I invested in a
rig for the RTLinux machine. I just want something that runs the RT
kernel for now.

The last time I tried with KVM, the rt kernel would panic on me while
loading some modules I suspect. So, if I'm going to use QEMU (No KVM),
running on a i386 host, running a i386 RTLinux guest, would I need to
apply any special patches to make sure the panic didn't occur.

See this thread for it hanging up in VMWare:
http://osdir.com/ml/linux.real-time.rtlinux.general/2004-11/msg00076.html

Apparently the rtl_time module causes the panic. Has this been taken
care of in the latest kernel?

Thanks,
Vivek
