[Xen-devel] add a hypercall to make hypervisor call Xen key handlers?
Keir, currently if we want to dump VMCS, we have to trigger the xen key handler using Xen serial console, but lots of machine come without serial port. so how about adding a hypercall to make hypervisor call Xen key handler instread from Xen serial console? then we can use "xm dmesg" to check dumpped content. sometimes this method will be very useful, like to check if a guest is using EPT or if FlexPriority is turned on. -Xin _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
