Availability risk? Sure, but that's 99.9% my own doing (constant experiments, etc)
Security risk? Not in the slightest. I'm running an up to date proxmox which is just KVM+QEMU with some scripting and a website on top, basically. I know how to setup IOMMU groups and such. If it's good enough for the big cloud providers, it's good enough for me.
Yeah primarily I'm concerned with availability. I have a "production" hypervisor now with all of the household services running on it that I've promised my spouse I wouldn't mess around with which cuts off one avenue of experiments.
