We use mostly KVM (Red Hat) and more and more FreeBSD jails at my work place. I also have extensive experience with VirtualBox. While KVM has proven very stable for our use cases I am having really hard time imagining myself to run Firewall as KVM instance, LDAP server or a mail server. File server is another case where I just can't imagine anything but bare metal. One of the reasons is that we use only ZFS on file servers. VirtualBox looks like a toy but unless you are looking to squeeze performance it was good enough for simple production user cases in our experience. We still use it as a simple desktop VM to test our software with Internet Explorer (no we are not doing web development but rather very deep machine learning tools with web interfaces). I have zero experience with VMware. I am also stuck with a single Debian Xen host and one guest. The machine is set to be retired for a long time not because we are not happy with Xen but because the hardware is dying but I can't get my hands around doing it. I would be happy to remove last Debian from the place. OpenBSD, FreeBSD/TrueOS/FreeNAS plus Red Hat on computing nodes and desktops is too much diversity already.
