Hi all,what's the reason for disabled MSR device in Xen 3.0-unstable? I need to touch MSR on my SMP box on bootup to fix one annoying BIOS issue but it can't be done from within Xen dom0. I have blindly enabled the driver but accessing it fails. I believe I could add the appropriate MSR setup code right into xen(.gz) kernel, but I'm not sure I'll be able to run it on both CPUs at least once. All I need is write two long ints to one MSR on both CPUs. Is there any way to do this in Xen? Thanks!
