October 2024 - Libguestfs - Libguestfs List Archives

by tyler＠spectrocloud.com

Hi rwmjones. Is this list of supported guests: https://libguestfs.org/virt-v2v-support.1.html up to date? If yes, are there any plans to support RHEL 8 and 9 and Windows 2017+?

[PATCH nbdkit 0/3] server: Implement TCP fastopen (TFO)

by Richard W.M. Jones

TCP fastopen is a little-known feature for omitting part of the normal 3-way handshake. It's implemented in Linux (since ~2014), Windows (since 2016), macOS and FreeBSD, but this implementation probably only works on Linux. The heavy lifting is done by the kernel, and the userspace changes needed (on Linux, at least) are very minor. I'm mainly posting this to save the patch series. After going down a rabbit hole testing and benchmarking this, it seems to make no discernable difference that I can see, or any benefit must be under the margin of error from measurement. It's probably safe to include this feature, but on the other hand if it doesn't do anything it seems to just add unnecessary complexity. There is a corresponding libnbd series which also contains the benchmark program, which I'll post in a moment. Rich.

Note that guestfs now requires json-c (JSON library) instead of Jansson

by Richard W.M. Jones

Libvirt recently moved from yajl (another JSON library) to json-c, because yajl is dead upstream. So that we are using just one JSON library (eg. in Linux distros), I also moved libguestfs, guestfs-tools and virt-v2v over to using json-c. This change takes effect in: - libguestfs >= 1.55.1 (development branch) - guestfs-tools >= 1.53.4 (development branch) - virt-v2v >= 2.7.1 (development branch) (Previous versions like the just released stable libguestfs 1.54.x and virt-v2v 2.6.x branches are NOT changed, and will still require Jansson). That's the easy bit. The _complicated_ bit is what happens if you mix up old libguestfs with new guestfs-tools or virt-v2v (probably the other way round too, but I didn't test that). It depends if you're using Jansson >= 2.14 or older Jansson. If using Jansson >= 2.14, you can freely mix old/new packages. (The reason is to do with symbol versioning introduced in Jansson 2.14). If using Jansson < 2.14 then you'll hit this error caused by a conflicting symbol across the Jansson and json-c libraries: qemu-img info: JSON output did not contain ‘format’ key If you see that error happening it's because you're mixing old and new libguestfs, guestfs-tools, virt-v2v, AND using Jansson < 2.14. The solution is not to mix them, or if you can't do that, update to the latest Jansson and recompile everything.

[PATCH supermin v2] prepare: Use stable owner, group and mtime in

by Richard W.M. Jones

Probably best to quote SOURCE_DATE_EPOCH in the command rather than blindly trusting that the contents are sensible. Rich.
