Krish Sadhukhan b91991bf6b KVM: nVMX: Check GUEST_DR7 on vmentry of nested guests ... According to section "Checks on Guest Control Registers, Debug Registers, and and MSRs" in Intel SDM vol 3C, the following checks are performed on vmentry of nested guests: If the "load debug controls" VM-entry control is 1, bits 63:32 in the DR7 field must be 0. In KVM, GUEST_DR7 is set prior to the vmcs02 VM-entry by kvm_set_dr() and the latter synthesizes a #GP if any bit in the high dword in the former is set. Hence this field needs to be checked in software.
