Yes, but you need nested kvm support in the host (which is not available in stock el6), and to install the "nestedvt" hook. More about it in http://community.redhat.com/blog/2013/08/testing-ovirt-3-3-with-nested-kvm/
Is that what the vhost custom property is for?
Nope, that's to turn off a certain type of vNIC optimization that used to be detrimental to certain guests.
Is there anything else that I need to do beside installing those vdsm hooks?

well on el6 this won't work, due to missing support of passing on the nested-vt flag, you could run a newer libvirt/kvm version on your el6 installation, if you really want/need this, but I would not encourage you to do so. Am 27.06.2014 14:14, schrieb Maurice James:

You need to check if nested KVM support is enabled on your machine cat /sys/module/kvm_intel/parameters/nested If the answer is "N": echo "options kvm-intel nested=1" > /etc/modprobe.d/kvm-intel.conf Then reboot. This and vdsm-hook-nestedvt package should be enough.
