That may be true for some virtualization software, but not for all.
My "day job" is as a system programmer for IBM mainframe systems,
and among my duties is responsibility for a z/VM system. In z/VM,
nested virtualization is not difficult, pointless, or unstable. I routinely
install a new release of z/VM in a virtual machine running under
the production release of z/VM, for example. There's even instructions
in IBM's installation manuals for how to do this.
z/VM is probably the most robust virtualization platform available
anywhere, having been developed, tweaked, and honed by IBM since 1967.
But it has two distict disadvantages: (1) it is proprietary, for-charge
software and (2) it only runs on IBM mainframes.
