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