what is virtunixd ? Is there such a daemon?
by Claudio Fontana 19 Apr '22

19 Apr '22

Hello, as I experiment with virsh migration commands (and probably I do things that don't make sense), I got an error I could not understand: # virsh migrate centos7 unix:///tmp/netcat.sock error: Failed to connect socket to '/var/run/libvirt/virtunixd-sock': No such file or directory What is "/var/run/libvirt/virtunixd-sock" ? Should I have a "virtunixd" process running? I am building with non-modularized libvirtd currently, but I could not find a virtunixd module either... Thanks, Claudio

[PATCH] qemu: Fetch info on NVDIMM-s too when updating memory devices
by Michal Privoznik 19 Apr '22

19 Apr '22

Sometimes it may come handy to learn what address is a NVDIMM mapped to inside a guest. While users can provide an address they want to have NVDIMM mapped to, it's optional. Fortunately, when a domain is being started we issue the 'query-memory-devices' monitor command and the reply is the same for 'dimm' and 'nvdimm' types. Therefore, updating NVDIMM address is trivial.

[libvirt PATCH] util: Fix stubs for virProcessGet{Stat,Sched}Info()
by Andrea Bolognani 19 Apr '22

19 Apr '22

Commit d73852c49962 moved the original QEMU-specific helpers to the utils module, which resulted in build failures on non-Unix platforms due to the unconditional use of Unix-only symbols such as _SC_CLK_TCK. To deal with that situation, commit d7c64453aa0e made the helpers Linux-only and added stubs for other platforms that, when called, would always fail with ENOSYS. However the original helpers had been carefully written so that, while they would only be able to produce useful output on Linux, they would still succeed on the other Unix platforms where we build the QEMU driver. Restore the original behavior so that calling APIs such as virDomainGetInfo() can once again work on FreeBSD and macOS.
