libguestfs-test-tool output

Description of problem:
The libguestfs-test-tool is failing on my Ubuntu.
I tried to reproduce the problem in a VM, but i couldn't.

Can you explain me why the kernel is crashing ?
I don't understand what's happening, and i can't figure it out with the debug provided by the tool.

Version-Release number of selected component (if applicable):
libguestfs0: 1:1.32.2-4ubuntu2

How reproducible:
not reproducible.

Actual results:
Log output attached.


Expected results:
libguestfs-test-tool succeed.


Thanks a lot.

Also, i booting on Ubuntu's standard kernel:

$ uname -a
Linux tarrma-Latitude-E7440 4.13.0-26-generic #29~16.04.2-Ubuntu SMP Tue Jan 9 22:00:44 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

And i don't understand why there is another kernel info (kvmi) on which i'm also worked that appears in the logs:

Booting from ROM...
\x1b[2J[    0.000000] Linux version 4.15.0-kvmi+ (tarrma@tarrma-Latitude-E7440) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.5)) #2 SMP Thu Jan 4 18:26:54 EET 2018

Here you can see that QEMU is using "Linux version 4.15.0-kvmi+" to boot i guess ?
but it doesn't match my current kernel.

Could this be the cause of the kernel panic ?

Thanks.

You're hitting this bug in supermin:

https://github.com/libguestfs/supermin/commit/158854e3ba4be7f6b8d81f662ddad98358ede1de

The solution is to upgrade supermin, backport just that patch,
or use an older host kernel.
