[PATCH 1/2] qemu: Switch to new -numa memdev=
Michal Privoznik
mprivozn at redhat.com
Tue May 12 14:52:46 UTC 2020
In v4.1.0-rc0~9^2~25 QEMU deprecated -numa mem= in favor of -numa
memdev= + -object memory-backend-*. However, the problem is these
two are incompatible. A domain started with older cmd line can't
be migrated to the newer one and vice versa. That is why libvirt
hasn't switched to the new cmd line, until now.
Starting with this commit, the new cmd line is used and this fact
is then recorded in domain private data object under
priv->forceNewNuma. This means, that the status XML and migration
cookie have it too and thus can instruct the other daemon which
cmd line to generate.
Unfortunately, migration from newer to older style will fail.
I'm saving the explicit check for a separate commit.
Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1783355
