[Xen-devel] `xl create` hang on skylake desktop



Hi Shannon:

I’m reporting that commit 38cd0664a6bf1c3b887992ea029d2bb516f52c59 is causing a
hang in the `xl create windows7` command on my skylake desktop.  This is a
regression from previous behavior.

    libxl/arm: Add the size of ACPI tables to maxmem

    Here it adds the ACPI tables size to set the target maxmem to avoid
    providing less available memory for guest.

I’ve was able to chase down this patchset by bisecting between
40277cded320efa32b86c0c9f01e33145eab5ee4 and
343f84be135e6f9e681960a9e235296eae159fc8.
I’ve confirmed that reverting 38cd0664a6bf1c3b887992ea029d2bb516f52c59 cleanly
avoids the hang.

I'm wondering how best to go forward,

Regards,
