Fixed upstream with https://github.com/libguestfs/libguestfs/commit/6befd1464d9939b9c15373b19296e796bea3d8d5 which is in libguestfs >= 1.37.22. Verified with the package: libguestfs-1.36.6-2.el7.x86_64 Steps: 1. Prepare a RHEL5.11 guest image: RHEL-Server-5.11-64-hvm.raw 2.

Create a image for test： # qemu-img create libguestfs_virt-resize_test.img 22474836480 4.

Before deleting the old disk, carefully check that the resized disk boots and works correctly. -------------------------------------------------------- The swap partition can be expanded successfully with the new libguestfs version. So verified this bug. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
