April 10, 20242 yr Hey there, I hope that is not a silly question, but I am currently solving problems on Truenas virtualization when I got a reply on the TN forum that the OS actually prefers Type I virtualization with passed through PCIe devices. https://forums.truenas.com/t/truenas-core-cant-execute-smart-check-not-capable-of-smart-self-check-resulting-in-bug/681/5 Because of that I wanted to ask if it is still possible to use the Xen based (Type I) virtualization in Unraid that Limetech used years ago or is that gone for good ? I saw there was a version 8 years ago that allowed both. How did that work back then ? Did you just switch the machine type ? Or was there a different template (like Windows 11, FreeBSD, etc.) ? Also has someone experience with virtualizing Truenas Core & Scale comparing them both ? Does it make a difference for the compatibility from KVM if my Guest OS is different than the Host (Core with FreeBSD) or if there is a same Guest Hosts systems (Scale with Linux base) performing better/ creating less problems (Considering PCIe passthrough) ? Thanks
April 11, 20242 yr Author it seems that I was not informed enough and KVM is in fact a Type 1 hypervisor. https://ubuntu.com/blog/kvm-hyphervisor Correct me if wrong .... I saw both over different sources. Still the question is Xen still out there for Unraid ? no idea ...
