Bandan Das 82a11e9c6f KVM: SVM: Add emulation support for #GP triggered by SVM instructions ... While running SVM related instructions (VMRUN/VMSAVE/VMLOAD), some AMD CPUs check EAX against reserved memory regions (e.g. SMM memory on host) before checking VMCB's instruction intercept. If EAX falls into such memory areas, #GP is triggered before VMEXIT. This causes problem under nested virtualization. To solve this problem, KVM needs to trap #GP and check the instructions triggering #GP. For VM execution instructions, KVM emulates these instructions.
