Hi,
I've just noticed that xenner doesn't work for 64bit xen guest kernels
on my new shiny barcelona box. The VM crashes when trying to access the
lapic. lapic setup is done before idt setup, register dump looks like
init state, thus it most likely is a triple fault resetting the vcpu.
Turning off npt fixes it.
xenner maps the lapic to ffff820000000000 (64bit guests) or fe900000
(32bit guests). 32bit works fine even with npt enabled.
host kernel is fedora 9 with kvm-69 modules.
ideas anyone?
cheers,
Gerd
