Subject: cpu_map: Disable cpu64-rhel* for host-model and baseline
X-Git-Tag: v8.4.0-rc1~241
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d2e4d66be35cd04da72e5f5129a8a4da6a931505;p=thirdparty%2Flibvirt.git

cpu_map: Disable cpu64-rhel* for host-model and baseline

These ancient RHEL-only CPU models should not really be used by any CPU
definition created by libvirt. We keep them just for backwards
compatibility with domains which might still be using them.
