libvirt is:
+ A toolkit to interact with the virtualization capabilities of recent
versions of operating systems, see our project goals for details.
+ A long term stable C API
+ A set of bindings for common languages
+ A CIM provider for the DMTF virtualization schema
+ A QMF agent for the AMQP/QPid messaging system
libvirt supports:
+ The KVM/QEMU Linux hypervisor
+ The Xen hypervisor
+ The LXC Linux container system
+ The OpenVZ Linux container system
+ The User Mode Linux paravirtualized kernel
+ The VirtualBox hypervisor
+ The VMware ESX and GSX hypervisors
+ The VMware Workstation and Player hypervisors
+ Virtual networks using bridging, NAT, VEPA and VN-LINK.
+ Storage on IDE/SCSI/USB disks, FibreChannel, LVM, iSCSI, NFS and filesystems
libvirt provides:
+ Remote management using TLS encryption and x509 certificates
+ Remote management authenticating with Kerberos and SASL
+ Local access control using PolicyKit
+ Zero-conf discovery using Avahi multicast-DNS
+ Management of virtual machines, virtual networks and storage
I'm fairly sure that the NetBSD part of the bridging code still needs
some more work, but I'll leave that as an exercise for someone more
versed in it than I am.
