I used to use VirtualBox but now I use KVM with virt-manager exclusively.
I find the power and flexibility that comes with the tool-suite second
to none. I can connect to local or remote hosts without any drama, all
over SSH, Kerberos, or certs (also policykit or simple user/group
I get virtio device support (nic, ata, balloon) and pci-passthrough if I
want it. Supports qcow2, vdi, vmdk, raw images as well as LVM devices.
Multiple storage pools.
I can migrate live machines on the fly, including migration of storage
images (like vmotion I guess). Also works in clusters on GFS and CLVM
for failover if that's your thing. Can snapshot and restore machines
with qcow2 images. Memory ballooning, can hotplug CPUs, RAM, disks. I
can emulate most CPUs, from a 486 or Westmere, to arm, mips, sparc, ppc.
I can turn also on or off extensions like SSE, set the number of cores
and threads, even pinning.
I can have create isolated or forwarded networks (nat/route), vlans, bonds.
Oh, and SPICE.
I've found that kvm support is better on Fedora than Ubuntu, primarily
because they seem to run newer versions (and maybe because libvirt is
RedHat sponsored). I've run into errors using a newer version of
virt-manager on Fedora to create new machines on CentOS though because
the backend is older and doesn't support things I might want to use,
like SATA. Just have to watch that or use a tool on the host to create
