Re: [Libguestfs] libguestfs kernel panic

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 ?
