[PATCH v2] qapi: net/tap: deprecate vhostforce option
by Vladimir Sementsov-Ogievskiy 01 Sep '25

01 Sep '25

This option doesn't make sense since long ago (10 years!) commit 1e7398a140f7a6 ("vhost: enable vhost without without MSI-X"). Prior 1e7398a140f7a6, to enable vhost for some specific kind of guests (that don't have MSI-X support), you should have set vhostforce=on (with vhost=on or unset). Since 1e7398a140f7a6, guest type doesn't matter, all guests are equal for vhost-enabling options logic. The current logic is: vhost=on / vhost=off : vhostforce ignored, doesn't make sense vhost unset : vhostforce counts, enabling vhost Currently you may enable vhost several ways: - vhost=on - vhostforce=on - vhost=on + vhostforce=on - and even vhost=on + vhostforce=off - they are all equal. Let's finally deprecate the extra option. Also, fix @vhostforce documentation.

The 11.7.0 release of both libvirt and libvirt-python is tagged and signed tarballs are available at https://download.libvirt.org/ https://download.libvirt.org/python/ Thanks everybody who helped with this release by sending patches, reviewing, testing, or providing feedback. Your work is greatly appreciated. * New features * Allow setting the log level of Cloud Hypervisor Users can now configure the verbosity of Cloud Hypervisor by setting the "log_level" option in ch.conf * bhyve: experimental NAT networking support The bhyve driver now has experimental NAT networking support using the Packet Filter (pf) firewall. * bhyve: domain statistics reporting The bhyve driver now supports querying domain block, interface, and memory statistics. Not all statistics fields are supported though. * Improvements * bhyve: improve 'efi' configuration autofill When a domain is configured with ``<os firmware='efi'/>``, NVRAM configuration is now autofilled. Enjoy. Jirka
