Subject: [Qemu-devel] [PULL 04/10] target-i386: Remove xlevel & hv-spinlocks option fixups
Date: Tue, 14 Jun 2016 17:59:02 -0300	[thread overview]
Message-ID: <1465937948-548-5-git-send-email-ehabkost@redhat.com> (raw)
In-Reply-To: <1465937948-548-1-git-send-email-ehabkost@redhat.com>

The "fixup will be removed in future versions" warnings are
present since QEMU 1.7.0, at least, so users should have fixed
their scripts and configurations, already.

In the case of libvirt users, libvirt doesn't use the "xlevel"
option, and already rejects HyperV spinlock retry count < 0xFFF.
