I'm having trouble examining xen stack traces using crash. I have a full xen dump image and can examine the stack traces for any active vcpu. But when I try to trace a non-active vcpu, I seem to get a copy of the stack trace for the last pcpu the non-active vcpu ran on. For example: crash> vcpus VCID PCID VCPU ST T DOMID DOMAIN 0 0 ffff8300dfdfc080 RU I 32767 ffff8300dc250080 1 1 ffff8300dbe7e080 BL 0 0 ffff8300dfd90080 2 2 ffff8300dbe7c080 BL 0 0 ffff8300dfd90080 3 3 ffff8300dbe7a080 BL 0 0 ffff8300dfd90080 4 4 ffff8300dbe78080 BL 0 0 ffff8300dfd90080 5 5 ffff8300dbe74080 BL 0 0 ffff8300dfd90080 6 6 ffff8300dbe72080 BL 0 0 ffff8300dfd90080 7 7 ffff8300dbe70080 BL 0 0 ffff8300dfd90080 8 8 ffff8300dbe6e080 BL 0 0 ffff8300dfd90080 9 9 ffff8300dbe6c080 BL 0 0 ffff8300dfd90080 10 10 ffff8300dbe6a080 BL 0 0 ffff8300dfd90080 11 11 ffff8300dbe68080 BL 0 0 ffff8300dfd90080 12 12 ffff8300dbe66080 BL 0 0 ffff8300dfd90080 13 13 ffff8300dbe64080 BL 0 0 ffff8300dfd90080 14 14 ffff8300dbe62080 BL 0 0 ffff8300dfd90080 15 15 ffff8300dbe60080 BL 0 0 ffff8300dfd90080 0 11 ffff8300dbe52080 BL U 7 ffff8300dbfc0080 crash> bt 11 PCPU: 11 VCPU: ffff8300dfdc8080 #0 [ffff8300dbe3fbe0] kexec_crash at ffff828c8010cd8c #1 [ffff8300dbe3fc00] panic at ffff828c801205fe #2 [ffff8300dbe3fcc0] show_stack at ffff828c8013c1f3 #3 [ffff8300dbe3fcf0] do_general_protection at ffff828c8013f07e #4 [ffff8300dbe3fd10] vpic_get_highest_priority_irq at ffff828c8015a2a3 #5 [ffff8300dbe3fd48] svm_asid_inc_generation at ffff828c8015c95e #6 [ffff8300dbe3fd70] vpic_intercept_pic_io at ffff828c8015ae9e #7 [ffff8300dbe3fd98] __context_switch at ffff828c8012570e #8 [ffff8300dbe3fe20] handle_exception_saved at ffff828c801884be #9 [ffff8300dbe3fea8] restore_all_xen at ffff828c8018809b #10 [ffff8300dbe3fed8] idle_loop at ffff828c80125c2f crash> This is the vcpu that crashed Xen.
