Would not be opposed to the change, it should work on platforms where we have 
no hardware virt capability. We (releng) are reaching out to the lvm team to 
see what can be done to make device-mapper work in a chroot, if it is 

Switching to using qemu would require lmc to learn a lot of details about 
running vms for different arches. But it would enable making images for non 
native arches as the commands are mostly the same. 

To use kvm would we need to bind mount /dev/kvm into the chroot?
