[PATCH] spec: Relax NBD_OPT_LIST_META_CONTEXTS
by Eric Blake
Using OPT_SET_META_CONTEXTS is stateful (it is documented to wipe out
any previously-requested contexts, and we just tightened the spec to
clarify that starting TLS also wipes it out). But
OPT_LIST_META_CONTEXTS is not stateful; and in fact, with a
SELECTIVETLS server, it can be handy to list the meta contexts
available on an unencrypted export, then enable encryption, and then
further list what contexts are available on encrypted exports (as the
server is permitted to let them differ). Thus, while a wise client
will renegotiate structured replies after the starttls, there's no
reason to forbid a server from answering a client that uses
list_meta_contexts prior to encryption without also requesting
structured replies.

[PATCH] appliance: Fix searching for shared libraries on usr-merged Debian systems
by Hilko Bengen
If /lib is a symlink to usr/lib, paths to shared libraries as
determined by ld.so may differ from dpkg's file lists.
We turn the filename search pattern into a glob expression by
prefixing it with a '*', so the required packages are found again:
$ dpkg -S /lib/x86_64-linux-gnu/libpcre2-8.so.0
dpkg-query: no path found matching pattern /lib/x86_64-linux-gnu/libpcre2-8.so.0
$ dpkg -S */lib/x86_64-linux-gnu/libpcre2-8.so.0
libpcre2-8-0:amd64: /usr/lib/x86_64-linux-gnu/libpcre2-8.so.0

Fwd: libnbd | Failed pipeline for master | 2e381ac2

>From the log:

opensuse zypper seems to be failing with a recoverable error:
Resolving package dependencies...
Problem: the to be installed glib2-devel-2.68.3-4.1.x86_64 requires 'libglib-2_0-0 = 2.68.3', but this requirement cannot be provided

libglib-2_0-0-2.68.3-4.1.x86_64[repo-oss]
Solution 1: downgrade of libglib-2_0-0-2.68.4-1.1.x86_64 to libglib-2_0-0-2.68.3-4.1.x86_64
Solution 2: do not install glib2-devel-2.68.3-4.1.x86_64
Solution 3: break glib2-devel-2.68.3-4.1.x86_64 by ignoring some of its dependencies
Choose from above solutions by number or cancel [1/2/3/c/d/?] (c): c
I wonder if this is something that libvirt-ci should handle better?
I found this thread which seems to indicate there's no way to force
zypper to pick an option:
https://www.linuxquestions.org/questions/suse-opensuse-60/how-to-pre-sele...
which is kind of annoying. But maybe --force-resolution is worth a try?

[PATCH] build: Define HAVE_RPM, HAVE_DPKG and HAVE_PACMAN
by Alexandre Iooss
When using option `--with-distro`, `HAVE_RPM`, `HAVE_DPKG` and
`HAVE_PACMAN` are not defined and make the configure phase fail.
This makes sure that these conditionals are always defined.

Re: [Libguestfs] [libguestfs/libguestfs] Is it possible to mount the entire disk raw? (#72)

nbdfuse, part of the libnbd project, can do this (with writes). In
fact there is an example of doing exactly this in the manual:
https://libguestfs.org/nbdfuse.1.html#Use-qemu-nbd-to-read-and-modify-a-q...
https://gitlab.com/nbdkit/libnbd
By the way I would be extremely wary of any tool which claims to
process qcow2 files but is not using qemu code to do it. nbdfuse uses
qemu-nbd (ie qemu code).

Hi there,
Is there possiable that virt-p2v can convert Physical computer online? Which means do not reboot or start it through U disk.
Do we have plan on this, is there any other tool can do this?
Thanks

nbdcpy: from scratch nbdcopy using io_uring
by Abhay Raj Singh
In a previous email, Mr. Jones suggested, writing a test implementation of
nbdcopy from scratch. First of all, thank you, Mr. Jones, as I got a better
perspective of the problem and the solution.
I have almost written the bare-bones implementation for handling
NBD-related stuff on which I will base the io_uring core piece by piece. It
is written in C++, as I am more comfortable with it. But, made it easily
translatable to C.
I have been working on a solution and have documented the current approach,
it would be great if you have a look at it and let me know what you think.
Approach document:
https://gitlab.com/rathod-sahaab/nbdcpy/-/blob/dev/docs/SOLUTION.md
Thanks and regards,
