Complete!

After that downgrade of my supermin package to the latest one provided by the 
ol8_kvm_appstream repo, supermin and libguestfs is now working fine !

Thanks, once again 

(maybe it was an incompatibility between the libvirt+el8.7 package and the 
supermin+el8.8 package, which was resolved when the supermin package was 
downgraded to the supermin+el8.7 package)

Dennis

No I don't think so.

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 /src/format-ext2-init-bin.h )

(3) Attach the copy of /src/format-ext2-init-bin.h or send it to me 
by email if it's too big for the list.  You might have to compress it.

Ok, Looking at my original installation procedure, including the slight tweaks 
to get libvirt-7 loaded, and checking the current server ... it appears the 
libvirt-7 packages mention the O/S version (eg el8.7), and there are packages 
for several versions, but not for el8.8 ... and yet my server (after patching) 
is now running OL 8.8 ... is that the issue ?

Then the supermin embedded init process appears to crash.  That's
