All,

Could latest crash version (b349598) could work on Linux 4.6.4 Xen Dom0?

It seemed that crash only could support open dump files, instead of running 
directly without a kernel core.

Please let me know whether my understanding is correct or not.

Daniel,

If my understanding is correct, I’m wondering do you have the plan to support 
this crash use case on Xen Dom0?

Here are detailed information, just FYI,

On Linux kernel 4.6.4 based Xen Dom0, I ran crash directly with kernel debug 
info installed,

# crash

crash: p2m array in new format is unreadable.



The error message was from below patch, which indicated that it only works for 
dump file case,

https://github.com/crash-utility/crash/commit/c3413456599161cabc4e910a0ae91dfe5eec3c21

In the patch, the XEN_CORE_DUMPFILE check excluded the case running crash 
without a kernel file,

                } else if (symbol_exists("xen_p2m_addr")) {
                        if (!XEN_CORE_DUMPFILE()) >>>>>>>>>>>>> hit the 
condition here
                                error(FATAL, "p2m array in new format is 
unreadable.");
