The error comes from sgdisk running on the guest, so it is a bug in sgdisk or maybe a problem with the guest filesystem itself. The closest I can find is this report from a few years ago: https://listman.redhat.com/archives/libguestfs/2018-May/msg00009.html What is the guest? And what version of sgdisk are you using? You could also try something like: $ virt-rescue --ro -d 138093b9b33345c38e58efa014036bd8 ><rescue> sgdisk /dev/sdb -i 1 Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-builder quickly builds VMs from scratch http://libguestfs.org/virt-builder.1.html _______________________________________________ Libguestfs mailing list [email protected] https://listman.redhat.com/mailman/listinfo/libguestfs
