If you are using standard tools in Linux, even without the hardware
virtualization acceleration for kvm, virt-manager / libvirt and all the
kvm tools will work. It will just use qemu without hardware
acceleration, for about a 50% performance hit.
So something you can do on laptops even without hardware virtualization.

Thanks. I started looking at KVM too. My laptop doesn't have the
hardware virtualization for testing but centos has been the plan as
the boot os so kvm may be the answer.

Great. Nice to hear about stuff in production before I "make the leap".
Any trick about installing xen virtual machines I should be aware of?
If you are starting from scratch at this point, I'd highly suggest looking
at
doing KVM instead of Xen. That's what all the major linux distros (Red
Hat,
Ubuntu, Suse) are supporting now, and are building their tooling around.
It's
a better place to invest your time.
Especially if you're using RH/Fedora/Centos. A while back there
were some issues building a kernel for the OS that boots the machine
("dom0"). The patching wasn't really possible for a _long_ time and
Redhat Corp jumped ship to promoting KVM. The latest distro that had a
working kernel for the boot OS was so old it wasn't even supported. I
believe that's gotten better, but it's very clear that xen is no longer a
first class citizen.
Apologies if that sounds prejudicial - I'm just trying to warn you
that xen has been unfixably broken for a stretch of years in the past, and
that makes me nervous. I'm using KVM and have been very happy with it.
Cheers,
- Bill
