Good day!
I'm trying to make working qemu-kvm with hardened gentoo on hardened kernel.
When i'm using CONFIG_PAX_KERNPAGEXEC and CONFIG_PAX_MEM_UNDEREF qemu just start
and go to infinite loop and take 100% of one of my CPU core. adn it
even can't be killed.
Also it is dont give answer for qemu monitor/remote gdb.
When I'm changed these two values as disabled, qemu-kvm now start, and
stop (i mean qemu monitor show that virtual machine is running, but no
any activity/output). Also it's load about 0%.
See details in bug http://bugs.gentoo.org/show_bug.cgi?id=363713

Hope this info help improve qemu-kvm.

Best regards,
Anton Kochkov.
