./emulators/qemu, CPU emulator using dynamic translation

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 7.0.0nb2, Package name: qemu-7.0.0nb2, Maintainer: pkgsrc-users

QEMU is a FAST! processor emulator using dynamic translation to achieve
good emulation speed, QEMU has two operating modes:

* Full system emulation. In this mode, QEMU emulates a full system
(for example a PC), including a processor and various peripherals.
It can be used to launch different Operating Systems without rebooting
the PC or to debug system code.
* User mode emulation (Linux host only). In this mode, QEMU can launch
Linux processes compiled for one CPU on another CPU. It can be used
to launch the Wine Windows API emulator or to ease cross-compilation
and cross-debugging.

== System emulation ==

=== Incompatible changes ===

Consult the [https://qemu-project.gitlab.io/qemu/about/removed-features.html \ 
'Removed features' ] page for details of suggested replacement functionality

=== New deprecated options and features ===

Consult the [https://qemu-project.gitlab.io/qemu/about/deprecated.html \ 
"Deprecated Features"] chapter of the QEMU System Emulation User's \ 
Guide for further details of the deprecations and their suggested replacements.

Additional note: The QEMU project currently considers to drop the slirp \ 
submodule in future releases, i.e. the QEMU tarball won't embed the code for \ 
user mode networking in the future anymore, so that an external libslirp \ 
installation is required. Most OS distribution already ship a libslirp package \ 
nowadays (except for OpenBSD which is already known and hopefully will be fixed \ 
soon), but if you are still using another OS distribution that does not provide \ 
a libslirp package yet, please send a note to the \ 
[[Contribute/MailingLists|qemu-devel mailing list]] and ask your OS vendor to \ 
include such a package in the next release.

=== Memory backends ===

=== Block device backends and tools ===
* Fleecing backup has been made more flexible: Fleecing backup means exposing a \ 
temporary snapshot of an actively used image, and having the copy-before-write \ 
(CBW) filter (or historically the backup block job) copy data there from areas \ 
written by the guest to the active image, before they are overwritten, so that \ 
the snapshot keeps representing the point-in-time state of the disk when the \ 
snapshot was created.  This snapshot can then be read (either by qemu itself \ 
using the backup or mirror block jobs, or by outside users e.g. via an NBD \ 
export) to create a backup.  As of qemu 7.0, instead of reading the snapshot \ 
image directly, it can also be accessed through the new snapshot-access block \ 
driver, by installing such a node on top of the CBW filter.  Doing so has some \ 
advantages over accessing the snapshot image directly; for example, the image \ 
can then be in any format (not just COW formats like qcow2), because the CBW \ 
filter keeps track of its allocation bitmap.  Once an a
rea has been backed up, users can send a discard request to mark it as done, so \ 
that the CBW filter will not potentially copy it to the snapshot image on a \ 
subsequent guest write.  Furthermore, the CBW filter now has a bitmap parameter \ 
that allows limiting its scope as specified by the bitmap at the time the CBW \ 
filter node is created.
* A bug in caching block status has been fixed that was causing over-eager \ 
treatment of a format layer as all data rather than detecting holes, if an \ 
earlier block status query had merely been checking for which portions of the \ 
backing chain were allocated.  While the bug did not affect guest-visible data, \ 
it caused some performance regressions, particularly noticeable and easy to \ 
trigger when using 'qemu-nbd --allocation-depth'.
* The ''qemu-nbd'' program has gained a new ''--tls-hostname'' parameter to \ 
allow TLS validation against a different hostname, such as when setting up TLS \ 
through a TCP tunnel, and now supports TLS over Unix sockets.
* The SSH driver supports sha256 fingerprints with pre-blockdev command line \ 
configuration syntax.
* The SSH driver will print the actual fingerprint and its type when failing to \ 
validate a host key.

=== Tracing ===

=== Miscellaneous ===

* The -sandbox 'spawn' filter, will now correctly block use of the clone syscall \ 
for spawnnig processes, while allowing thread creation
* The -sandbox 'spawn' filter, will now entirely block use of the clone3 syscall \ 
entirely since there is no way to access its flags parameter from seccomp to \ 
distinguish thread vs process creation
* The -sandbox 'spawn' filter, will now block setns, unshare and execveat \ 
syscalls since they are not desired.

== User-mode emulation ==

* fixed a bug that caused issues mapping the ARM commpage on 32 bit builds

=== binfmt_misc ===

=== Hexagon ===

== TCG ==

User-mode emulation (linux-user, bsd-user) will enforce guest alignment \ 
constraints and raise SIGBUS to the guest program as appropriate.

=== ARM ===

Support for for ARMv4 and ARMv5 hosts has been dropped.  These older Arm \ 
versions do not have support for misaligned memory access; such support was \ 
added to ARMv6.  Since ARMv5 is quite old, it is presumed that such systems do \ 
not have sufficient RAM to even run QEMU, and so practically speaking no systems \ 
are impacted.

== Guest agent ==
* Support Windows 11 for <code>guest-get-osinfo</code> command
* Fix memory leaks in Windows <code>guest-get-fsinfo</code> command

== Build Information ==

=== Python ===

=== GIT submodules ===

=== Container Based Builds ===

* a large number of containers are now updated by lcitool
* TESTS and IMAGES environment variables can be used filter again when building \ 
against all docker targets

=== VM Based Builds ===

=== Build Dependencies ===
* xfs libraries are not needed anymore for build, since the only ioctl used by \ 
qemu which was defined there got local implementation.  With this, \ 
--enable-xfsctl configure option is also gone.

=== Windows ===

=== Testing and CI ===
