When a disk image uses LVM thinp (thin provisioning), the guestfs_lvs API would return the thinp pools. This confused other APIs because thinp pools don't have corresponding /dev/VG/LV device nodes. Filter the LVs that are returned using "lv_role=public". Thanks: Fabian Deutsch --- daemon/lvm.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-...

When listing logical volumes, ignore the ones which don't get activated automatically. No /dev/VG/LV device node is created for these ones which confuses APIs that attempt to do 'guestfs_lvs' followed by opening the device node. Note that 'guestfs_lvs_full' is unaffected by this change. --- daemon/lvm.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/daemon/lvm.c b/daemon/lvm.c index 8bef4d5..529e20d 100644 --- a/daemon/lvm.c +++ b/daemon/lvm.c @@...

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

Hi, I am using guestfish to write some files into guest file system of my KVM domain. As you know, I have to mount guest disk at a position in the filesystem before I write any files into it , e.g.: mount /dev/VolGroup00/LogVol00 / But the problem is how I can get guest filesystem info without login guest. Now I have to power on the KVM domain, login the guest, remember which

Partition number was being passed to guestfs___check_for_filesystem_on based on an index in list_partition. However, this ignores the possibility of multiple block devices. This change makes guestfs___check_for_filesystem_on examine the passed-in device directly to determine if it is a whole device, or what its partition number is. --- src/guestfs-internal.h | 2 +- src/inspect-fs.c | 45

...ot; now works on paths which contain absolute symlinks (Pino Toscano). "guestfs_glob_expand" now has an optional "directoryslash" boolean parameter which controls whether trailing slashes are returned for directory names (Pino Toscano). "guestfs_lvs" will no longer return LVs which have the "activationskip" flag set. The reason is that such LVs have no "/dev/VG/LV" device node and so code which read the list of LVs and then probed the devices themselves would immediately fail. You can use "g...

This rather complex set of patches allow non-optargs functions to gain optional arguments, while preserving source and binary backwards compatibility. The problem is that we cannot add an optional argument to an existing function. For example, we might want to add flags to the 'lvresize' API which currently has no optional arguments.
