Description of problem: We're trying to do an offline local file Xen VPS to KVM VPS conversion. The source is a dd raw image backup file. The dd image is from a CentOS 6 Xen hvm host CentOS 7.6 VPS. We're trying to move it to a replacement KVM host (in a later step). When running virt-v2v on the backup image file it errors with "guestfsd: error: aug_init: / (flags 1): Internal error (please file a bug): get.c:1296:Unexpected lens in concat 80..80" Version: [root@virt-v2v ~]# virt-v2v -V virt-v2v 1.38.2rhel=7,release=12.el7_6.2,libvirt [root@virt-v2v ~]# How reproducible: every run Steps to reproduce: 1. export LIBGUESTFS_BACKEND=direct 2. virt-v2v -i disk vm6881_backup -o local -os /tmp Actual results: errors and exits Expected results: completion without a program aborting error Log snip: ... libguestfs: trace: v2v: vfs_type = "ext4" [ 51.4] Checking for sufficient free disk space in the guest [ 51.4] Estimating space required on target for each disk [ 51.4] Converting CentOS Linux release 7.6.1810 (Core) to run on KVM libguestfs: trace: v2v: aug_init "/" 1 guestfsd: <= aug_init (0x10) request length 52 bytes guestfsd: error: aug_init: / (flags 1): Internal error (please file a bug): get.c:1296:Unexpected lens in concat 80..80 Expected: label[/usr/share/augeas/lenses/dist/lvm.aug:61.5-.19:]r Actual: star[/usr/share/augeas/lenses/dist/lvm.aug:61.13-.35:]R libguestfs: trace: v2v: aug_init = -1 (error) virt-v2v: error: libguestfs error: aug_init: aug_init: / (flags 1): Internal error (please file a bug): get.c:1296:Unexpected lens in concat 80..80 Expected: label[/usr/share/augeas/lenses/dist/lvm.aug:61.5-.19:]r Actual: star[/usr/share/augeas/lenses/dist/lvm.aug:61.13-.35:]R If reporting bugs, run virt-v2v with debugging enabled and include the complete output: virt-v2v -v -x [...] libguestfs: trace: v2v: close libguestfs: closing guestfs handle 0xe70f40 (state 2) ...
Pino, is this for augeas component instead?
Please run virt-v2v with the -v -x options and attach the complete output to the bug.

Added the debug output requested. Command ran: LIBGUESTFS_BACKEND=direct LIBGUESTFS_TRACE=1 LIBGUESTFS_DEBUG=1 virt-v2v -v -x -i disk vm6881_backup -o local -os /tmp
Hm still the same issue, an internal error in augeas. From what you said, I take that the host (i.e. where virt-v2v runs) is CentOS 7.6, is that correct? Which version of augeas is installed there? Please paste the output of `rpm -qa '*augeas*' | sort` As the input is a local disk, we can try to diagnose this issue a bit more: please run $ guestfish -v -x --ro -a vm6881_backup -i aug-init / 517 (note that it will take much longer than the virt-v2v invocation you used so far) and attach here its complete stdout + stderr.

Hello, Guestfish output requested attached. Yes fully updated CentOS 7.6 test VPS to do the conversion. [root@test-virtv2v-conversion ~]# rpm -qa '*augeas*' | sort augeas-libs-1.4.0-6.el7_6.1.x86_64 [root@test-virtv2v-conversion ~]# Thanks for assist!
It does seem as if this is genuinely an Augeas bug. The debug output is: guestfsd: error: aug_init: / (flags 517): Internal error (please file a bug): get.c:1296:Unexpected lens in concat 80..80 Expected: label[/usr/share/augeas/lenses/dist/lvm.aug:61.5-.19:]r Actual: star[/usr/share/augeas/lenses/dist/lvm.aug:61.13-.35:]R libguestfs: trace: aug_init = -1 (error) libguestfs: error: aug_init: aug_init: / (flags 517): Internal error (please file a bug): get.c:1296:Unexpected lens in concat 80..80 Expected: label[/usr/share/augeas/lenses/dist/lvm.aug:61.5-.19:]r Actual: star[/usr/share/augeas/lenses/dist/lvm.aug:61.13-.35:]R
