Which virtualization and guest server to choose on Windows 10?

Question

FreeBSD

I am transferring a home server with 2 sites on mysql 5.6, php 5.6, nginx 1.8 to joomla (~4 GB database) and wordpress (~300 articles) and a mail server to iredmail (for small mailing and site maintenance) from a physical server to a virtual one on Windows 10 (my main 4-core Phenom with 8 GB of RAM with the prospect of expanding to 16 on the system SSD)
I want to give 4 for a virtual machine and after upgrading 8 GB, respectively. Now this is all on an old Core Duo physical computer with 4 GB of RAM under FreeBSD 10.2 (ufs), the swap sometimes overflows, although I only add articles to the database there. The budget is only enough to expand the memory to 16 GB on a computer with Windows 10.
Advise which hypervisor and which guest server to put in it? More familiar with FreeBSD, less with Ubuntu and Debian. FreeBSD attracts with stability, ease of updates and predictability, and while it is under Hyper-V, it remains to configure and transfer data. Is it worth putting zfs inside a virtual machine? Change Mysql to MariaDB?
There is Ubuntu server 15.10 under VirtulBox, if I have time to compare performance, I'll leave it.

Answer 1

Stop necrophilia. Bury FreeBSD.
Do not use interim releases.
Install Ubuntu GNU/Linux 14.04 LTS, in the summer of 2016 decide whether to upgrade to 16.04 or not.
I can’t tell you what to use for virtualization under Windows, I’m not strong in bestiality, but if there is native Hyper-V, then why do you need children’s toys from the left desk, such as VB from Oracle?

Answer 2

Try looking at Xen as well. I use it as a pure hypervisor. 5 virtual machines are spinning on it. Including FreeBSD (I like ipfw nuclear), 3 Debian's (nginx-testing proxymod)), Win2012 for review. You can connect to it through XenCenter (on Win). There are snippets on the Internet on how to remove VM backups and put them somewhere
