The guestfs_canonical_device_name API was rewriting /dev/mdX as /dev/sdX. This is wrong since (eg) /dev/sd0 is not a device name, so if you pass the canonicalized name back to the API it will fail. virt-v2v was one tool doing this. --- src/canonical-name.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/canonical-name.c b...

This breaks virt-inspector, at least when we run the test suite which has a phony Ubuntu guest with a non-existent /dev/mapper/* in its /etc/fstab. The manpage for guestfs_canonical_device_name[1] is sort of ambiguous here. It says that "/dev/mapper/*" is Converted to /dev/VG/LV form using guestfs_lvm_canonical_lv_name. and guestfs_lvm_canonical_lv_name will certainly return an error for a non-existent name. However it does also say: Other strings are returned unmodifie...

Rich.

Consolidate and extend the use of funky start_element() etc macros. Rich.

Hey there! Here are a few patches to fix unrelated things: one fixes the configure for older ncurses releases having no pkg-config files. The other two are fixing what Richard mentioned about guestfs subvolumes display Cédric Bosdonnat (3): configure: handle older version of ncurses api: add mountable_device and mountable_subvolume fish: fix btrfs subvolumes display in error case

Hi all, Here is version 2 of the patch series, including the changes for Pino's remarks.

v1 was here: https://www.redhat.com/archives/libguestfs/2018-October/msg00047.html However it was broken in a few ways. First of all the documentation was broken because "/**" enhanced comments were not permitted on macros. This is fixed in the new 1/4 patch. Secondly we didn't use single_element() everywhere possible, which is fixed in the new 4/4 patch. Lastly I've

The existing mechanism was clunky, slow and used ~ 10 MB of local disk. Rich.

version 2: - Turn the "unrecognised disk label" error into errno == EINVAL - Fix virt-alignment-scan - Rework the fix for virt-v2v bug 1232192 (see description of patch 3/3)
