Re: [Libguestfs] libguestfs kernel panic

Hi Richard, Thank you ! I was not aware of 'supermin' before, but that definitely pointed me in the right direction ... Looking at the supermin packages, I was running the latest package, from 'ol8_appstream' repo ... not from the 'ol8_kvm_appstream' repo.

The main thing is to try to find out which part of init.c is crashing (and later, why). As I don't have OEL, could you try extracting the init binary. It's buried in the supermin executable, so it's best to get it from the debug sources: (1) debuginfo-install supermin (2) rpm -ql supermin-debugsource | grep src/format-ext2-init-bin.h (eg. it will print something like <blahblah>/src/format-ext2-init-bin.h ) (3) Attach the copy of <blahblah>/src/format-ext2-init-bin.h or send it to me by email if it's too big for the list.
