I already read everything yesterday and it is not clear and doesn't answer my technical questions, no use for me to keep reading the wiki at this point

The nas part of unraid is like lvm with parity basically? meaning since there is no hardware involve i will not have a speedboost also? Would be great to have a benchmark. About parity, can you have URE when resilvering? that is the main issue of raid5 (with one parity disk) and if unraid can have the same issue it will be a definite no for me. Speaking about ressource consumption, how does the unraid os server does compare to other os like fedora for example ?

Hello, i'm the new guy around, developper from france i join the world of virtualization after reading the excellent vfio blogpost. I came here because i have a lot of questions, articles keep contradict themselves and i'm kinda lost atm. My main question here is about unraid, xen and kvm. I truly do not understand what unraid is, i'm sorry if people think the "what is unraid" page is clear but for me it isn't, so, what is it clearly? At first i thought this was a virtualization server but it appears i was wrong, the only thing i got is that unraid is for dealing with datas. Also since it appears i can create software like raid with unraid, does it support two disks parity? Speaking of xen, it is suppose to be a bare metal hypervisor aka i can install it with no os, so i don't understand why i can install xen with fedora centos etc... Is this process switching the host system to a dom0 system, putting the os on top of xen and not the other way around? Because if not i don't understand why people would install xen of top of an os when you can just use kvm to run your vms. What i want to do, what i did, using kvm and fedora, was to create myself a windows 10 gaming virtual machine. The problem i have here is that if i want to create a raid, to be able to read datas from both fedora and my windows vm i will need either create a nas like raid inside of my machine, meaning i will create the raid on fedora and put it on my local network (and i believe that is what unraid is for?) or create a raid using hardware (like a pci raid card) and pass it to my vm when i start it. The later solution including a 200dollars card, i would prefer to use the first solution. The second problem is that most of the time i do not use fedora, i boot, i launch my vm, and that's it. Some might ask "then why did you bother yourself with virtualization in the first place". Well, as a developper i will need soon (after my internship which will end soon) a linux workstation, so that's why, also the possibility to have an osx vm is for me a plus (tried to emulate osx on top of windows, takes too much ressources). Anyway, before jumping into xen and unraid i need some answers, so if anyone could help me clarify all this it would be gladly appreciated.

The tricky part here is your graphic card, same as mine, would like an answer too on is it possible to passthrough this. For what you want to do with arch, you will simply disable one output using xrandr, your gtx will not be used by arch though, otherwise you will have to reboot arch like stated above.

So if i understand correctly unraid is a bare metal hypervisor like xen? How are performances compare to running a gaming vm on a system like fedora using qemu + libvirt? Also does someone knows if unraid supports recent gpu? (gtx 980 ti)
