Can you extend that line of tracing to print the bad value (vlapic_get_reg(vlapic, APIC_DFR))? I'd say it's most likely that the guest is writing zeroes into reserved-1 bits of the DFR, and we should be ignoring the modification of those bits. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
