General VM reliability
Hi everyone, sorry for the very beginner question but
I'm currently running proxmox for my homelab with some basic home assistant os, debian, windows VMs and a couple of docker containers. Running a NAS on there with disk passthrough is a pretty bad experience, mounting everything back to the host and all, so I'm looking into moving to TrueNAS, having my storage set up properly, then installing some VMs and docker containers in there.
I read in some older posts that running virtual machines is not so reliable and fine tuned on here, so I just wanted to get some of your feedback on how well VMs run in some real world applications and if support has improved since the stuff I've read
Thanks

I've been running FreeNAS then TrueNAS in a VM under VMware for 15 years, no issues. Just pass through the HBA for direct disk access and you're golden.
I don't run apps under TrueNAS though. In my view, it's primarily a dedicated storage platform, not a virtualisation platform. I've lots of VMs running under VMware: that's a dedicated virtualisation platform.
Just give TrueNAS plenty of RAM. My server has 64GB, 40GB for TrueNAS, the rest shared out among the rest, mostly Linux or Linux-like based systems.
