That referred to an address that doesn't correspond to RAM. You can use addresses like these in a real processor. But the manual says that "if the “use TPR shadow” VM-execution control is 1, VM entry ensures that the virtual-APIC address is 4-KByte aligned" (24.6.8 Controls For APIC Virtualization). This is the check that is missing.
