--- Comment #3 from FREEBSD at bfeitell.users.panix.com ---
I can confirm this boot failure on a CentOS7 host running both
FreeBSD-11.0-RC3-amd64 and pfSense-CE-2.4.0-DEVELOPMENT-amd64-latest (FreeBSD
11), as guests.

Changing the CPU type to Westmere allows the VMs to boot and provides support
for for the AES-NI instructions provided by the host CPU, as described in:

The host CPU is an AMD A8-7670K

Pfsense 2.3.2 (FreeBSD 10.3) boots fine as either Opeteron_G5 or via the host
CPU copy facility built into virt-manager.

Adding "hw.use_xsave=0" to /boot/loader.conf.local makes no difference.
