Add a warning message and instructions how to(not) virtualize Truenas

Problem/Justification
Since joining this forum, I witnessed multiple users losing their pool, because they went about the wrong way, when they virtualized Truenas.

Impact
Users will less likely lose their data.

User Story
When installing Truenas, a big fat warning message will appear, telling the user that virtualizing Truenas for non experimental purposes is not recommended. It will also give instructions (e.g. passthrough of a controller, not single discs, possible blacklisting of the HBA) of the “proper” way if virtualization is needed.

There’s still a resource on this on the old forum. Big warnings in TrueNAS come too late because one should really look this up in advance and design the system accordingly.

It seemed to be very fashionable for YouTubers to make videos on virtualizing TrueNAS

“And boom, there you go, just like that, what could be easier”

After describing a data loss recipe…

Meanwhile, there are legitimate reasons to virtualize truenas without PCIe he pass through, for example, testing new electric eel releases :wink:

People who would heed (or even read) those kinds of warnings are the ones that make the effort to research about TN, my 0,02 €.

This is true, but sometimes people who want to do the best don’t understand the technology but if they got a pointer would follow those instructions.

I.e. CMR Vs SMR
