Bug Fixes

BZ#603000

Previously, the do_part_get_bootable() API function parsed the output of parted with an assumption that the partition layout on the guest image was well ordered. As a consequence, the part-get-bootable API would produce an incorrect result or even terminate with disks where the partitions were not in the usual order or were missing. With this update, the source code is modified so that libuguestfs can correctly handle disks with unordered partitions.

BZ#627835

Previously, libguestfs protocol lost synchronization when using the upload command in the guestfish command line tool before mounting any disks. Uploading files failed and an error message was reported due to the library and the daemon sending cancel messages in an incorrect order. With this update, if the daemon detects cancellation, it sends the remaining data in its output buffer instead of discarding it.

BZ#666578, BZ#678231

Previously, if guests used the LABEL or UUID (Universal Unique Identifier) identifiers for swap devices in the guest /etc/fstab file, the virt-inspector utility reported the unknown filesystem error message. The source code has been modified, and the utility now works correctly and no longer displays error messages.

BZ#682980

Prior to this update, libguestfs could have incorrectly detected Red Hat Enterprise Linux Desktop distributions as a "redhat-based" instead of "redhat". As a consequence, the virt-v2v utility failed to convert such guests. With this update, libguestfs is modified to detect these distributions correctly as "redhat". Now, conversion is successful.

BZ#684980

Calling the guestfs_kill_subprocess() function and then closing the connection handle by calling guestfs_close() could cause the libguestfs connection to become unresponsive. The source code has been modified to close the connection correctly so that the connections no longer hangs.

BZ#685009

After the resize operation, the ntfsresize utility marks the file system as requiring a consistency check. As a consequence, an error message can appear when resizing the same file system multiple times in a row without rebooting the virtual machine. With this update, the ntfsresize(8) manual page describes this behavior.

BZ#688062

Previously, when pressing the tab key in the guestfish command line tool, the mapped devices created by luks-open were not listed. With this update, /dev/mapper/ paths are added to tab-completion and the devices are displayed when pressing the tab key.

BZ#690358

Querying a fully-virtualized guest works reliably only for Linux guests. With this update, the virt-inspector(1) manual page is modified to note this.

BZ#692394

Previously, the inspect-list-applications API and virt-inspector2 utility did not detect 32-bit applications installed under the WoW64 (Windows 32-bit on Windows 64-bit) emulator on a 64-bit Windows guest. With this update, the source code is modified to display the installed applications with their description in the output.

BZ#693306

Iterables passed instead of plain lists could cause the RuntimeError exception to be thrown when calling libguestfs' Python interface. The Python bindings have been modified so that any iterable argument can be used as a list.

BZ#695881

Previously, the virt-make-fs tool generated the qemu-img command which contained an incorrect decimal point in the output. As a result, an error message was reported. With this update, the source code is modified so that the virt-make-fs tool invokes qemu-img correctly in all cases.

BZ#713529

Due to incorrect mounting of guest file systems, the virt-v2v utility could fail when the guest /etc/fstab file contained file systems marked with LABEL. This update modifies the source code so that the file systems are mounted correctly. As a result, virt-v2v no longer fails.

BZ#725563

With this update, libguestfs is rebuilt against the latest parted package, which adds support for the Legacy BIOS Bootable flag in the GPT (GUID Partition Table) attribute field.

BZ#727178

Prior to this update, a build error prevented libguestfs from working on LUKS (Linux Unified Key Setup) encrypted disks. As a result, loading of shared libraries failed with an error message. An upstream patch has been applied to address this issue and libguestfs now works correctly on LUKS devices.

BZ#729887

This update adds the description of typecheck lenses in the guestfish(1) manual page.

BZ#730248

The guestfish(1) manual page has been modified to mention that guestfish --remote run should not be used in a command substitution context.

Enhancement

BZ#672491

Prior to this update, the guestfs_last_errno() function was not exposed in the Perl bindings. As a consequence, it was not directly possible to determine the precise cause of some failures. To fix this problem, guestfs_last_errno() is now exposed in the Perl bindings.

BZ#810251

This enhancement update moves the python-libguestfs package from the Red Hat Enterprise Linux 6 Optional channels to the Red Hat Enterprise Linux 6 base channels. This update does not make any other changes to these packages.
