[Xen-devel] [Patch] Avoid mov-from/to-cr8 crashing Xen when APIC=0
If APIC=0 in VMX configuration file, VLAPIC(v) in mov_from_cr()/mov_to_cr() will be NULL, so calling vlapic_get_reg()/vlapic_set_reg()/vlapic_update_ppr() will crash Xen. Since a guest OS, which uses mov-from/to-cr8, requires APIC=1, we had better only crash the related domain instead.
