Re: [Libguestfs] libguestfs supermin error

Hi Rich I have installed supermin from source supermin_5.1.7.orig.tar.gz on powerpc and have applied the patch as reffered by you.Know I'm getting following error .. libguestfs-test-tool ************************************************************ * IMPORTANT NOTICE * * When reporting bugs, include the COMPLETE, UNEDITED * output below in your bug report. * ************************************************************ PATH=/bin:/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/sbin:/usr/local/bin SELinux: sh: getenforce: command not found guestfs_get_append: (null) guestfs_get_autosync: 1 guestfs_get_backend: direct guestfs_get_backend_settings: [] guestfs_get_cachedir: /var/tmp guestfs_get_direct: 0 guestfs_get_hv: /usr/bin/kvm guestfs_get_memsize: 768 guestfs_get_network: 0 guestfs_get_path: /usr/local/lib/guestfs guestfs_get_pgroup: 0 guestfs_get_program: libguestfs-test-tool guestfs_get_recovery_proc: 1 guestfs_get_selinux: 0 guestfs_get_smp: 1 guestfs_get_tmpdir: /tmp guestfs_get_trace: 0 guestfs_get_verbose: 1 host_cpu: powerpc64 Launching appliance, timeout set to 600 seconds. libguestfs: launch: program=libguestfs-test-tool libguestfs: launch: version=1.26.1 libguestfs: launch: backend registered: unix libguestfs: launch: backend registered: uml libguestfs: launch: backend registered: direct libguestfs: launch: backend=direct libguestfs: launch: tmpdir=/tmp/libguestfsJF3lvj libguestfs: launch: umask=0002 libguestfs: launch: euid=1000 libguestfs: [00000ms] begin building supermin appliance libguestfs: [00000ms] run supermin libguestfs: command: run: /usr/bin/supermin libguestfs: command: run: \ --build libguestfs: command: run: \ --verbose libguestfs: command: run: \ --if-newer libguestfs: command: run: \ --lock /var/tmp/.guestfs-1000/lock libguestfs: command: run: \ --copy-kernel libguestfs: command: run: \ -f ext2 libguestfs: command: run: \ --host-cpu powerpc64 libguestfs: command: run: \ /usr/local/lib/guestfs/supermin.d libguestfs: command: run: \ -o /var/tmp/.guestfs-1000/appliance.d supermin: version: 5.1.7 supermin: package handler: debian/dpkg supermin: acquiring lock on /var/tmp/.guestfs-1000/lock supermin: build: /usr/local/lib/guestfs/supermin.d supermin: build: visiting /usr/local/lib/guestfs/supermin.d/base.tar.gz type gzip base image (tar) supermin: build: visiting /usr/local/lib/guestfs/supermin.d/daemon.tar.gz type gzip base image (tar) supermin: build: visiting /usr/local/lib/guestfs/supermin.d/excludefiles type uncompressed excludefiles supermin: build: visiting /usr/local/lib/guestfs/supermin.d/hostfiles type uncompressed hostfiles supermin: build: visiting /usr/local/lib/guestfs/supermin.d/init.tar.gz type gzip base image (tar) supermin: build: visiting /usr/local/lib/guestfs/supermin.d/packages type uncompressed packages supermin: build: visiting /usr/local/lib/guestfs/supermin.d/udev-rules.tar.gz type gzip base image (tar) supermin: build: 121 packages, including dependencies supermin: build: 7109 files supermin: build: 7109 files, after removing unreadable files supermin: build: 4939 files, after matching excludefiles supermin: build: 4941 files, after adding hostfiles supermin: build: 4944 files, after munging supermin: failed to find a suitable kernel (host_cpu=powerpc64).
