We worried about getenv's safety (lack of) for quite a while when we
were writing libguestfs, which uses a lot more environment variables
in many more places. But we decided there was simply nothing we could
do about it, and it was easier not to worry :-)

Richard Jones,
For RHEL >= 9 / x86-64 guests we cannot use the default qemu CPU
(eg. "qemu64"), and so we have a mechanism for conversion to indicate
to the output modes that a more capable CPU is required. We
previously picked cpu='host-passthrough' (ie. the equivalent of qemu's
-cpu host). However this is

RHEL >= 9 and compatible distros like Rocky >= 9 will not boot using
the default qemu CPU. You will see an error at boot:
Fatal glibc error: CPU does not support x86-64-v2
Instead you need to use -cpu host.

I don't believe that would help since other libraries or the main
program might be calling setenv. We cannot do anything
After previous changes, it is now safe to use the parallel thread
model in this plugin. The locking in pool.c protects a single curl
handle from being used from multiple threads.
An advantage of this is we can now combine the curl plugin with
filters such as readahead and scan.
---
Introduce the concept of a pool of curl handles from which the main
code has to take a handle (get_handle()), and later return it to the
pool (put_handle()). When a handle is taken from the pool it can be
used exclusively by the main code until it is returned.
The "pool" only has at most one
This commit implements the curl handle pool. By default it can grow
to up to 4 curl handles, shared between all NBD connections. You can
change this using the new connections=N parameter.

In a future commit we will create a pool of libcurl handles. In order
to prepare for that, split out the libcurl handle and associated
fields and buffers, from the plugin handle. The plugin handle (for
the moment) contains a pointer to the libcurl handle so there is still
a 1-1 relationship
Tidy up previous work on this plugin so that every global is declared
in "curldefs.h". Move the HAVE_CURLINFO_CONTENT_LENGTH_DOWNLOAD_T
macro to this header file too.

This experimental series changes the way that the curl plugin deals
with libcurl handles. It also changes the thread model of the plugin
from SERIALIZE_REQUESTS to PARALLEL.
Currently one NBD connection opens one libcurl handle. This also
implies one TCP connection to the web server. If you

Hi Eric,

(1) nbdkit-curl-plugin does not currently advertise multi-conn. However

When the user calls nbd_set_socket_activation_name before calling
nbd_connect_system_socket_activation, pass the name down to the server
through LISTEN_FDNAMES. This has no effect unless the new API has
been called to set the socket name to a non-empty string.

This is an alternative approach to
https://listman.redhat.com/archives/libguestfs/2023-January/030535.html
After discussing this with Dan Berrange we came to the conclusion that
you really might want to set LISTEN_FDNAMES to arbitrary short strings
(or not set it). Especially when talking to
To allow us to name the socket passed down to the NBD server when
calling nbd_connect_systemd_socket_activation(3), we need to add the

Some small refactorings which should not affect the code:
- Use string_vector_reserve instead of checking each time we append.
- Get rid of the hard-coded length, and use strncmp (..., s, strlen (s)).
The compiler should compile this to the same code.

systemd allows sockets passed through socket activation to be named
with the protocol they require. We only ever pass one socket, name
it. This environment variable is currently ignored by qemu-nbd and

For -o rhv-upload, the -os parameter specifies the storage domain.
Because the RHV API allows globs when searching for a domain, if you
used a parameter like -os 'data*' then this would confuse the Python
code, since it can glob to the name of a storage domain, but then

Here's an updated version which supports read, write, flush,
write-zeroes, discard and FUA:

I was able to access a local file using the io_uring driver using
guestfish. You can try it like this:
$ ./nbdkit -fv blkio io_uring

(5) "The application is responsible for thread-safety. No thread
synchronization is necessary when a queue is only used from a single
thread. Proper synchronization is required when sharing a queue
between multiple threads."
Does this apply across multiple struct blkio handles? ie. Is there

This is an incomplete outline implementation for a libblkio plugin for
nbdkit. At the moment it only supports reading the same ("capacity")
of the device, and not even reading or writing. I have some questions
about the libblkio API before I can complete the plugin (see below).
The idea here is
BTW I'm on holiday, and I'm quite happy to go with whatever Laszlo
agrees with. He is also able to push it upstream.

We've had requests from products that use libguestfs & virt-v2v to
provide additional tooling for:
(a) Inspecting a virtual machine disk image to find out what virtual
devices it needs (ie. what drivers are installed in the guest).
(b) Taking a Windows disk image and injecting virtio drivers
Thanks, that is upstream in commit db831c167b.

If the virtio-win ISO contains drivers for Windows 11, Windows 2019 or
Windows 2022, and the guest matches these, then copy in the right
drivers. For this to work you will need libguestfs >= 1.49.8 which
allows osinfo to be used to detect Windows versions >= 10.
