9 These are the release notes for guestfs tools stable release 1.50.
10 This describes the major changes since 1.48.
11 Guestfs tools 1.50.0 was released on 7 February 2023.
13 Security
15 CVE-2022-2211
16 https://bugzilla.redhat.com/show_bug.cgi?id=2100862
17 A buffer overflow was found in the --key option of several guestfs
19 tools. For more information on this low severity bug see the bug
20 report above (Laszlo Ersek).
21 New virt-drivers tool
23 This new tool can examine a disk image to determine:
24 • Whether it uses BIOS or UEFI for booting
26 • What bootloader it uses (Linux only)
28 • What kernels may be chosen at boot time (Linux only)
30 • What device drivers (kernel modules) are installed
32 This is useful for determining how (or if) a guest can boot on a
34 virtualization hypervisor.
35 virt-customize
37 --selinux-relabel is now the default for SELinux guests. You no longer
38 need to specify this flag. In the rare case where you don't want to
39 relabel a guest after customizing it, you can use --no-selinux-relabel.
40 Note this is not needed for non-SELinux guests, it will do the right
41 thing automatically (Laszlo Ersek).
42 New --inject-qemu-ga and --inject-virtio-win operations which
44 respectively inject QEMU Guest Agent and virtio-win drivers into
45 Windows guests.
46 Rocky Linux guests are now supported (thanks Harry Benson).
48 virt-inspector
50 Virt-inspector now outputs the new <build_id> element containing the
51 guest build ID, if using libguestfs ≥ 1.50.
52 virt-sysprep
54 New "lvm-system-devices" operation for removing LVM2's system.devices
55 file. This avoids certain problems when cloning a VM (Laszlo Ersek).
56 Virt-sysprep supports guests using LUKS logical volumes on top of LVM
58 (Laszlo Ersek).
59 Common changes
61 All the tools supporting the --key option can now use Clevis/Tang to
62 decrypt full disk encryption using this network-based scheme (Laszlo
63 Ersek).
64 Build changes
66 Note that libguestfs now requires minimum OCaml 4.04. It will not
67 compile on RHEL 6.
68 Note that libosinfo is a new required dependency.
70 OCaml 4.14 is now supported.
72 "./configure --disable-ocaml" and "./configure --disable-perl" now
74 disable the OCaml- and Perl-based tools respectively (thanks Simon
75 Walter).
76 Experimental support for compiling on macOS.
78 When running "make check-valgrind", Valgrind logs are no longer written
80 to separate files under tmp/. Instead the output is written to the
81 normal test-name.log file.
