This is fixed upstream, but not in RHEL 7.2. Upstream fix: https://github.com/libguestfs/libguestfs/commit/33d2b4a7341830efeddb1f258ac77f67a8004d30 Upstream bug 1211996 Should be fixed by the rebase. It still failed with packages:
libguestfs-1.32.5-6.el7.x86_64
Steps:
1. Prepare an ppc64le guest image:
RHEL-7.1-ppc64le.qcow2
2. Create a tmp.qcow2 to only record the difference to backing_file:
# qemu-img create -f qcow2 -o backing_file=RHEL-7.1-ppc64le.qcow2 tmp.qcow2
# virt-inspector -a tmp.qcow2

virt-customize: error: host cpu (x86_64) and guest arch (ppc64le) are not
compatible, so you cannot use command line options that involve running
commands in the guest. Use --firstboot scripts instead.
If reporting bugs, run virt-customize with debugging enabled and include
the complete output:
virt-customize -v -x [...]
The error is still there.

Use --firstboot scripts instead. This is correct: you cannot run (easily, I'd say) ppc64le binaries using the x86_64 appliance built from the host. You need to try on a ppc64le host as well, like shown in comment #0.

I'm sorry I have pasted the wrong log I think... I should paste the one on ppc64le. Actually I tried first on x86_64 which gives the above error, then I tried on ppc64le it still fail as following: ---------------------------------------------------------- # uname -a Linux ibm-p8-rhevm-17.lab4.eng.bos.redhat.com 3.10.0-327.el7.ppc64le #1 SMP Thu Oct 29 17:31:13 EDT 2015 ppc64le ppc64le ppc64le GNU/Linux # virt-customize -a RHEL-7.1-ppc64le.qcow2 --install openssh [ 0.0] Examining the guest ...
