Re: [Xen-devel] exception handler caused by context switching and setting trap flag

["Paul Samon" <paul.samon@xxxxxxxxx>]

HVM guest's VMexit is handled by Xen itself (see xen/arch/x86/hvm/vmx/entry.S: vmx_asm_vmexit_handler if you're using an Intel VT-capable host) , not Dom0 (a PV guest) at all.

 

vcpu context switch itself doesn't cause VMexit.

      In dom0,which exception handler is used to handle VMexit caused by context switching in domU?

      If I want to replace the handler ,what should I do?

 Thanks.
