[Bug 1322441] Re: QEMU Windows guest unstable after random amount of time

[Matthew Anderson]

Based on the fact that flush_tlb_page() appears to be taking up most of
the CPU time when QEMU is 'frozen' I started playing with memory
settings. Disabling automatic NUMA balancing appears to have solved the
problem. echo 0 > /proc/sys/kernel/numa_balancing

The guest has been running 4+ hours now without an issue. I currently
have KSM and transparent huge pages enabled.
