How to disable TLSv1.0 for PCI Compliance in Apache 2.2

Just recently our PCI compliance scanner started complaining about TLSv1.0 being enabled on our web server, so I had to go figure out how to disable it. The following is what I ended up with in our VirtualHost config which did what I wanted it to:
<VirtualHost xx.xx.xx.xx:443>
        SSLEngine on
        SSLProtocol +TLSv1.1 +TLSv1.2
        SSLCompression off
        SSLHonorCipherOrder On
        Header always append X-Frame-Options SAMEORIGIN

PCI Compliance TLSv1.0I simply removed the "all" option I had there previously and just manually enabled the TLSv1.1 and TLSv1.2. I also added the "Header" bit so that common browsers wouln't put our site in frames.

Now, checking our SSL certificate using the SSL Server Test we get an A rating. The downgrade from A+ being due to an upstream older SHA1 hash that we have no way to change and doesn't directly effect the security of our site, so as far as I'm concerned we look good.

The draw back is that older machines, such as those running Windows XP and versions of Android older than 4.2.2 will no longer be able to connect to us. Sorry about that. Since this is required for PCI compliance, there's not much we can do.
