=head1 RELEASE NOTES FOR LIBGUESTFS 1.40
|
||||
|
||||
These release notes only cover the differences from the previous
|
||||
stable/dev branch split (1.38.0). For detailed changelogs, please see
|
||||
the git repository, or the ChangeLog file distributed in the tarball.
|
||||
|
||||
=head2 New features
|
||||
|
||||
=head3 New features in existing tools
|
||||
|
||||
Virt-inspector now displays the libosinfo short ID for guests
|
||||
(Pino Toscano).
|
||||
|
||||
Guestfish I<-N> will now generate 1G disks instead of 100M disks by
|
||||
default.
|
||||
|
||||
Virt-resize supports f2fs filesystems (Pino Toscano).
|
||||
|
||||
libguestfs-test-tool now supports bash tab completion
|
||||
(Pino Toscano).
|
||||
|
||||
The I<--machine-readable> option now supports sending output to files
|
||||
or stdout/stderr. This works uniformly across most OCaml-based virt
|
||||
tools, specifically: virt-builder, virt-builder-repository, virt-dib,
|
||||
virt-get-kernel, virt-resize, virt-sparsify, and virt-v2v (Pino
|
||||
Toscano).
|
||||
|
||||
Virt-builder I<--uninstall> option now works on SUSE
|
||||
(Sebastian Meyer).
|
||||
|
||||
Virt-builder now supports Windows. We are not able to ship Windows
|
||||
templates in the public respository for obvious licensing reasons, but
|
||||
if you are an MSDN subscriber you may build your own. See
|
||||
L<https://rwmj.wordpress.com/2018/09/13/creating-windows-templates-for-virt-builder/>
|
||||
|
||||
Many tools now support a I<--key> option allowing you to pass in
|
||||
decryption keys for filesystems stored in local files on the host
|
||||
rather than having to feed them in over stdin (Pino Toscano).
|
||||
|
||||
=head3 virt-v2v and virt-p2v
|
||||
|
||||
New I<-o rhv-upload> mode for directly uploading images to RHV,
|
||||
bypassing the Export Storage Domain (Tomáš Golembiovský, Nir Soffer,
|
||||
Daniel Erez, Pino Toscano).
|
||||
|
||||
New I<-o openstack> mode for directly uploading images to OpenStack
|
||||
and Cinder using OpenStack APIs.
|
||||
|
||||
Virt-v2v now has a general mechanism for input and output options:
|
||||
I<-io> and I<-oo>.
|
||||
|
||||
Virt-v2v can now install the RHV tools or QEMU GA in guests
|
||||
(Tomáš Golembiovský).
|
||||
|
||||
The huge manual has now been split into several smaller documents and
|
||||
is more focused on helping users to accomplish specific v2v tasks.
|
||||
|
||||
Multiple improvements to the OVF metadata when converting to RHV
|
||||
(Tomáš Golembiovský, Pino Toscano, Arik Hadas).
|
||||
|
||||
Virt-v2v can now convert Linux guests with split kernel packages,
|
||||
especially Ubuntu 18.04 (Pino Toscano).
|
||||
|
||||
Virt-v2v old I<--password-file> option has been replaced by I<-ip>
|
||||
(the old option remains for backwards compatibility).
|
||||
|
||||
Virt-v2v now preserves the VM Generation ID.
|
||||
|
||||
Virt-v2v has a new I<--mac> option allowing specific NICs to be mapped
|
||||
precisely to networks or bridges on the target.
|
||||
|
||||
New virt-v2v I<--print-estimate> option to estimate the size of data
|
||||
that virt-v2v will copy.
|
||||
|
||||
Virt-v2v is now usually able to remove open-vm-tools and VMware Tools
|
||||
from the Linux guest during conversion (Pino Toscano).
|
||||
|
||||
Virt-v2v can now support UEFI conversions to RHV (Tomáš Golembiovský).
|
||||
|
||||
Virt-p2v now prefers you to shut down instead of rebooting the machine
|
||||
after conversion has finished (Pino Toscano).
|
||||
|
||||
Virt-v2v now writes the libosinfo short ID to the libvirt metadata
|
||||
when using I<-o local> and I<-o libvirt> output modes
|
||||
(Martin Kletzander).
|
||||
|
||||
=head3 Language bindings
|
||||
|
||||
OpenJDK 10+ is supported (Pino Toscano).
|
||||
|
||||
Java bindings fixed for Gentoo host (Martin Kletzander).
|
||||
|
||||
=head3 Inspection
|
||||
|
||||
Support Kali Linux (Pino Toscano).
|
||||
|
||||
When inspecting mountpoints, look for F</etc/mdadm/mdadm.conf> as well
|
||||
as F</etc/mdadm.conf> (Nikolay Ivanets).
|
||||
|
||||
Improved support for OpenSUSE Tumbleweed (Pino Toscano).
|
||||
|
||||
=head3 Architectures and platforms
|
||||
|
||||
Miscellaneous macOS build fixes (Adam Robinson).
|
||||
|
||||
=head3 Other
|
||||
|
||||
Multiple documentation typos fixed (Yuri Chornoivan).
|
||||
|
||||
=head2 Security
|
||||
|
||||
See also L<guestfs-security(1)>.
|
||||
|
||||
=head3 CVE-2018-11806
|
||||
|
||||
Qemu's slirp (userspace networking) had several buffer overflows which
|
||||
could be triggered from the guest or network side.
|
||||
|
||||
=head2 API
|
||||
|
||||
=head3 New APIs
|
||||
|
||||
=over 4
|
||||
|
||||
=item C<f2fs_expand>
|
||||
|
||||
Expand an f2fs filesystem (Pino Toscano).
|
||||
|
||||
=item C<inspect_get_osinfo>
|
||||
|
||||
Get the libosinfo short ID for the inspected guest (Pino Toscano).
|
||||
|
||||
=item C<lvm_scan>
|
||||
|
||||
This rescans all PVs, VGs and LVs, optionally activating them.
|
||||
|
||||
=back
|
||||
|
||||
=head3 Other API changes
|
||||
|
||||
C<part_get_mbr_part_type> was reimplemented in OCaml
|
||||
(Nikolay Ivanets).
|
||||
|
||||
C<list_filesystems> now filters out MBR extended partitions
|
||||
(Nikolay Ivanets).
|
||||
|
||||
C<vgscan> has been deprecated. Use the new C<lvm_scan> API in
|
||||
preference.
|
||||
|
||||
=head2 Build changes
|
||||
|
||||
The JSON library switched from yajl to Jansson E<ge> 2.7 (Pino Toscano).
|
||||
|
||||
Support for The Sleuth Kit 4.5 (Pino Toscano).
|
||||
|
||||
Multiple improvements in the C<./configure> script (Lin Ma).
|
||||
|
||||
More out-of-tree build fixes (Hilko Bengen).
|
||||
|
||||
Some work on reproducible builds (Bernhard M. Wiedemann).
|
||||
|
||||
=head2 Internals
|
||||
|
||||
lvmetad is now used unconditionally, and is started much earlier in
|
||||
the appliance boot process. This fixes support for certain PV types.
|
||||
|
||||
On Debian, dash is installed inside the appliance and in virt-rescue
|
||||
(Pino Toscano).
|
||||
|
||||
The amount of RAM assigned to the appliance has been increased from
|
||||
500M to 768M (on x86_64, other architectures have different limits).
|
||||
This enables use of up to 255 disks when using recent Linux kernels.
|
||||
|
||||
Virt-v2v now models the source machine type (eg. i440FX, Q35 or virt).
|
||||
|
||||
Virt-p2v now generates configuration code automatically, also code for
|
||||
parsing the kernel command line.
|
||||
|
||||
Use C<LT_INIT> instead of C<AC_PROG_LIBTOOL>.
|
||||
|
||||
The OCaml C<JSON> code for parsing and serializing has been unified
|
||||
into a single abstract data type.
|
||||
|
||||
Most OCaml tools are now built using the PIC runtime. This has a
|
||||
performance penalty on i686, but is relatively free on other
|
||||
architectures and has security benefits.
|
||||
|
||||
The direct backend now queries the qemu binary for availability of
|
||||
KVM, instead of using a heuristic based on F</dev/kvm> (Andrea
|
||||
Bolognani).
|
||||
|
||||
Our "clever" libxml2 writer macros are now used consistently across
|
||||
all parts of the code base.
|
||||
|
||||
Qemu dropped I<-nodefconfig> without telling us. The equivalent
|
||||
I<-no-user-config> option is now used instead. Qemu also moved the
|
||||
C<serial> option from I<-drive> to I<-device>, again without any
|
||||
notice, and this is also fixed.
