This way the version string of each API can be used also in other generator modules. Mostly code motion, no actual behaviour changes. --- generator/c.ml | 21 ++++++++++----------- generator/docstrings.ml | 6 ++++++ 2 files changed, 16 insertions(+), 11 deletions(-) diff --git a/generator/c.ml b/generator/c.ml index 63dc09a..a2b9c94 100644 --- a/generator/c.ml +++ b/generator/c.ml @@

Virtio-net driver control queue implementation is not safe when used with VDUSE. If the VDUSE application does not reply to control queue messages, it currently ends up hanging the kernel thread sending this command. Some work is on-going to make the control queue implementation robust with VDUSE. Until it is completed, let's disable control virtqueue and features that depend on it.

To avoid breaking existing plugins, Python plugins wishing to use version 2 of the API must opt in by declaring: def api_version(): return 2 (Plugins which do not do this are assumed to want API version 1). --- plugins/python/example.py | 15 +++- plugins/python/nbdkit-python-plugin.pod | 61 ++++++++++----- plugins/python/python.c | 100

v2 was here: https://www.redhat.com/archives/libguestfs/2019-November/msg00163.html I pushed patch 1 (with spelling fix), patch 4 and patch 5 since those were previously ACKed on the list. Differences in v3: - Add error checking to PyModule_AddIntConstant. - Use API_VERSION constant instead of function. - Add max API version supported to --dump-plugin output. - Print API_VERSION selected by

Could we also permit the python code to declare a global variable instead of a function? But a

v3 was here: https://www.redhat.com/archives/libguestfs/2019-November/msg00209.html In v4: - Rebase on top of current master. Includes various fixes and updates required because of Nir's patches that went into master. - Fix api_version() -> API_VERSION in patch 2 noted previously on the mailing list. Rich.

And fill out most of the missing bits of the API. Rich.

This small series enables virtio-net device type in VDUSE. With it, basic operation have been tested, both with virtio-vdpa and vhost-vdpa using DPDK Vhost library series adding VDUSE support using split rings layout (merged in DPDK v23.07-rc1). Control queue support (and so multiqueue) has also been tested, but requires a Kernel series from Jason Wang relaxing control queue polling [1] to

v1: https://www.redhat.com/archives/libguestfs/2019-November/msg00153.html v2: - Fix implementation of can_cache. - Add implementation of can_fua. - Add a very thorough test suite which tests every command + flag combination.

Hi, I am using XEN-4.1.2 and linux-2.6.32 as dom0. After I upgraded stackless python from 2.5 to 2.7 (and rebuilt xen). XenAPI became unusable, I spent some time to investigate XenAPI,py, it looks fine. So, I guess xend has problem with python 2.7, because it always returned method unknown. Do I have to tweak xend to let it support python 2.7? Thanks, Eric /root # python Python 2.7.5 Stackless

We have an nbdkit plugin that lets you write NBD servers in Python. An example of an existing Python plugin is here: https://github.com/libguestfs/nbdkit/blob/master/plugins/python/example.py#L1 This morning I tried to modify the plugin to use the newer nbdkit API (version 2). One of the things that would change would be passing flags parameters to some functions, eg: def pwrite (h, buf,

I know there are lot of questions in here around this. I''ve tried all of them but none of them works. Basically, I''m trying to stub TwitterOAuth::Client so my test won''t call the real api every time. Here''s the bit from TwitterOAuth gem that I use. module TwitterOAuth class Client def initialize(options = {}) @consumer_key =
