qemu-kvm and XenServer missing MSRs

Hi,

i have seen some recent threads about running Xen as guest. For me it is still not working, but I have read that Avi is working on some fixes. I have seen in the logs that the following MSRs are missing. Maybe this is related:

cpu0 unhandled rdmsr: 0xce
cpu0 disabled perfctr wrmsr: 0xc1 data 0x0
cpu0 disabled perfctr wrmsr: 0xc2 data 0x0
cpu0 disabled perfctr wrmsr: 0x186 data 0x13003c cpu0 disabled perfctr wrmsr: 0xc1 data 0xfffffffffea6c644 cpu0 disabled perfctr wrmsr: 0x186 data 0x53003c

I had a different thread started which was dealing with memtest not working on Nehalem CPUs, at least 0xce was also involved there.
