7.112. libguestfs
Updated libguestfs packages that fix numerous bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The libguestfs packages contain a library, which is used for accessing and modifying guest disk images.
Bug Fixes
- BZ#801640
- Previously, when using the
resize2fs -M
command and an error due to lack of free space occurred, the returned error message was incorrect and could confuse the user. With this update, a proper error message is returned instead. - BZ#822626
- Due to a bug in the source code, an error occurred when using the
virt-ls --checksum
command and the following error message was returned:libguestfs: error: checksum: path: parameter cannot be NULL
The underlying source code has been modified andvirt-ls --checksum
now works as expected. - BZ#830369
- Due to the
guestfs_inspect_get_hostname()
function, thelibguestfs
-based commands did not work properly when an empty/etc/HOSTNAME
file was created on a Linux guest. This update applies a patch to fix this bug and thelibguestfs
based commands now work in the described scenario. - BZ#836573
- Previously, the
libguestfs
library did not handle the/dev/disk/by-id/*
paths. Consequently, it was impossible to examine a guest using commands with such a path and an error message was returned. With this update, a patch has been applied to fix this bug and thelibguestfs
library no longer returns error in this situation. - BZ#837691
- Previously, under certain conditions, writing to disks in the
qcow2
format could cause silent data loss. The underlying source code has been modified to prevent this behavior and writing to disks in theqcow2
format now works as expected. - BZ#838609
- Due to a race condition between the
guestmount
and thefusermount
tools, unmouting and then immediately using a disk image was not safe and could cause data loss or memory corruption. This update adds the new--pid-file
option forguestmount
to avoid the race condition between these tools and attempts to use disk images immediately after unmounting can no longer cause data loss or memory corruption. - BZ#852396
- Previously, the
libguestfs
library limited the total size of downloaded hive files from a Windows Registry to 100 MB. Consequently, an attempt to inspect systems with large amount of hive files causedlibguestfs
to return an error message. With this update, the limit was increased to 300 MB andlibguestfs
can now inspect a larger Widows Registry properly. - BZ#853763
- Previously, using the
file
utility to detect the format of a disk image could produce different output for different versions of this utility. The underlying source code has been modified and output is now the same for all versions of thefile
utility. - BZ#858126
- Due to a bug in the underlying source code, the
virt-inspector
tool failed to work with certain Windows guests. This update applies a patch to fix this bug andvirt-inspector
now supports all Windows guests as expected. - BZ#858648
- Due to recent changes in the iptables packages, the
libguestfs
library could not be installed with the new version of theiptables
tool. The underlying source code has been modified to fix this bug and the installation oflibguestfs
works as expected. - BZ#872454
- Previously, the
libguestfs
library detected the Red Hat Enterprise Linux 5.1 guests as NetBSD guests. This update applies a patch to fix this bug andlibguestfs
now detects Red Hat Enterprise Linux 5.1 guest correctly. - BZ#880805
- The
virt-df
command with-a
or-d
arguments works correctly only with a single guest. An attempt to use this command with multiple arguments, such asvirt-df -a RHEL-Server-5.9-32-pv.raw -a opensuse.img
, caused the disk image names to be displayed incorrectly. With this update, the plus sign (“+”) is displayed for each additional disk, so that the user can easily recognize them. In addition, the correct usage of thevirt-df
command has been described in thevirt-df(1)
man page.
