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?
