All task switches are emulated, so you can add tracing to hvm_task_switch() to check if a switch has occurred. An alternative is that the guest did another LTR while not being emulated? If you want to remember the last VMEXIT, you’ll have to add code to store state away somewhere to pick up on the next VMENTRY. -- Keir On 23/04/2009 15:08, "Tom Rotenberg" <tom.rotenberg@xxxxxxxxx> wrote: About the TR, i have re-checked it, and it seems like the TR value is still 0x58, althoug the LTR operation put 0x50 into it. Since, i looked at the LTR code you sent me, and it seems ok, i tend to suspect, that there was some kind of (hardware) task switch, which changed the TR value without me knowing, is it possible? because otherwise, i can't really explain why the TR value is different than what was loaded from the LTR operation... _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
