[PATCH v2 01/29] docs: Fix QEMU version wrt hypervclock
Posted by Michal Privoznik via Devel 1 week, 6 days ago
From: Michal Privoznik <mprivozn@redhat.com>

The hv-time feature was introduced in QEMU commit
v2.0.0-rc0~119^2~3 which means the first version the feature is
available in is 2.0.0. But our docs say 1.2.2. Fix it.

Those are libvirt versions, "qemu" means it's supported by our qemu
driver:

Good point, we should unify how we refer to features available only in
some drivers as currently some of the forms can be confusing. But that's
work for different series.
