As reported by Maxime at https://bugzilla.kernel.org/show_bug.cgi?id=204175: In vmx/nested.c::get_vmx_mem_address(), when the guest runs in long mode, the base address of the memory operand is computed with a simple: *ret = s.base + off; This is incorrect, the base applies only to FS and GS, not to the others. Because of that, if the guest uses a VMX instruction based on DS and has a DS.base that is non-zero, KVM wrongfully adds the base to the resulting address.
