[Libguestfs] [PATCH] v2v: Fix error on exit unmounting transfer ISO

If the transfer iso was mounted during conversion, virt-v2v would always give the following error on shutdown: (in cleanup) umount: /tmp/transferb7icam: umount: /sysroot/tmp/transferb7icam: not found at /home/mbooth/src/virt-v2v/blib/lib/Sys/VirtV2V/GuestOS/RedHat.pm line 1171. This was because the GuestOS::RedHat cleanup was being called implicitly on exit, which is after umount_all has been called explicitly on the libguestfs handle. This change garbage collects the guestos explicitly before the libguestfs handle. --- v2v/virt-v2v.pl | 3 +++ 1 files changed, 3 insertions(+), 0 deletions(-) diff --git a/v2v/virt-v2v.pl b/v2v/virt-v2v.pl index 08f1c8d..c7ebad3 100755 --- a/v2v/virt-v2v.pl +++ b/v2v/virt-v2v.pl @@ -366,6 +366,9 @@ END { sub close_guest_handle { + # Perform GuestOS cleanup before closing the handle + $guestos = undef; + if (defined($g)) { $g->umount_all(); $g->sync(); -- 1.6.6.1
