Hi everybody!
I am new in Xen and have a problem.
I use Intel-VT processor, Xen 3.3.0 (built from sources) and hvm-domain Windows Vista. I read in Intel Software Developer Manual about VMX-preemption timer. I want to cause periodic VM-exits and use this feature to do it. But I can't find preemption timer in Xen source codes. For example, there is not preemption timer among vmx exit reasons in \include\asm-x86\hvm\vmx\vmx.h. Does anybody know about VMX-preemption timer support in Xen?

Thank you,
Olga
