Not that other VM systems haven't suffered similar problems. But when real-world experience shows that, for example, Xen is no less vulnerable to the most damaging exploits than any other VM manager then the hypothetical security advantages evaporate away and it no longer becomes a useful justification for preferring Xen.

I've been a Linode customer for most of their 12 years, but my only complaint (and the reason I don't use them for anything I _really_ care about) is that they have always been very opaque about security.
