Description of problem: The HWADDR can not be removed from "ifcfg-*" file on RHEL system. "$type/$distro" has the value of "linux/rhel", which is not in the support list. In the script, net-hwaddr can be removed only when "$type/$distro" is linux/fedora: if [ "$net_hwaddr" = "yes" ]; then case "$type/$distro" in linux/fedora) ... esac fi Need to add redhat-based linux system into support list, like linux/fedora|linux/rhel|linux/centos|linux/scientificlinux. Version-Release number of selected component (if applicable): libguestfs-tools-1.16.15-1.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1. on latest rhel6.3 host, update to use the latest libguestfs-tool (1.16.15-1.el6) package 2. provision a rhel6 kvm guest (named rhel6u2-x64) 3. reset the domain: # virt-sysprep -d rhel6u2-x64 4. check HWADDR in the ifcfg-* file Actual results: The HWADDR is not removed from "ifcfg-*" files Expected results: The HWADDR is removed from "ifcfg-*" files.

Upstream commit: https://github.com/libguestfs/libguestfs/commit/5e054f873198b83947de328777d9ced3bfa39ad5 This fix will be backported to libguestfs 1.16.16.
Verified with libguestfs-tools-1.16.18-2.el6.x86_64.
