From: Bruce Rogers Date: Fri, 17 May 2013 16:49:58 -0600 Subject: increase x86_64 physical bits to 42 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Allow for guests with higher amounts of ram. The current thought is that 2TB specified on qemu commandline would be an appropriate limit. Note that this requires the next higher bit value since the highest address is actually more than 2TB due to the pci memory hole.
