Created attachment 1381553 [details] 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.
