No, it does not. Memory allocated to VMs is directly from system RAM. The amount of RAM you need to have in your system per VM is the amount you are assigning plus a 20-25% overhead reserve for the emulated components. The exact amount of overhead you need to have available is an undecidable problem to solve, as it can range based on the use of the guest and the amount of total system memory you are reserving for the VM(s) you have. As others have mentioned, we are not a competitor to ESXi or any of the other mainstream traditional hypervisors. They are designed to be SOLELY a virtualization host, focused entirely on the enterprise/cloud market, and are not user friendly. So there are many of the more traditional hypervisor features that we haven't built in just yet (like snapshotting) because while we want to do that, there are lots of nuances to doing that right when you support multiple filesystems and NAS functionality on top of the virtualization host capabilities. These are things that will come in due time. Same goes for vlan support. I also highly recommend leveraging the completely free trial to evaluate the software for yourself. All questions relating to performance are pointless because everyone's hardware and network is different. It's far easier to try it yourself for free than for anyone here to guess at what your experience might be unless you are coming to the table with a replica infrastructure to another user. Keep in mind, this isn't me saying, "don't ask the question," but it is me saying, "don't trust anyone's answer until you test it for yourself." Hope this sheds some light on things. Hi Jon, many thanks for your reply. Once my GPU arrives this week I will give the trial version a go.

Many thanks guys, this is really appreciated and I know the questions are kind of complicated. The last thing I want to know an answer is this question... Does unRAID create a physical file on the disk for the memory of each running VM? If it does not save memory on the disk while the VM's are running then you have me as a client. Many thanks again to everyone that helped answer my questions.

This is a bit of a shameless bump but I was wondering if anyone can answer some of the remaining questions.

@Aderalia & @ashman70 - Many thanks for the answers. I really appreciate it. @Aderalia - I know Linus as I watch his videos quite often so I have seen that video. It is one of the main reason I have come across unRAID. He does not cover much in his video about the hyper visor, I don't think he even mentioned it once. @ashman70 - Yes I use ESXi to manage a forensic lab in my workplace and got used to it so it is probably one of the reason why I like some of their features. The biggest gripe I had with ESXi for my personal use was that the free version allows only up to 8 core per VMs and NVIDIA GPUs are not supported on purpose for pass-through, I know this is NVIDIA gimping the cards. Price for unRAID is also very attractive for personal use compared to ESXi.

Uhh... nobody?

Shameless bump...

Hello Ladies and Gents, So I am finally at a point where I need to toggle between multiple systems at the same time and keep them completely isolated. I game and do a lot of forensic research under Linux and after some research I have come across unRAID. From everything so far it seems too good to be true and for the licence price it is even better but I do have a lot of questions that I have not found anything very specific. Here are my specs which should make answering my questions much easier I hope... Asus X99-E WS Intel i7 5960X 64GB RAM DDR4 128GB Samsung SM951 M.2 NVMe 1.2TB Intel 750 Series PCIE NVMe 1.2TB Intel 750 Series PCIE NVMe 2 x PASCAL (SLI) OR POLARIS (CROSSFIRE) PCIE GPUS Here are my questions and I hope you can answer me. It will most likely determine if I will buy unRAID or not. 1. Will I be able to fully utilize the performance of the above hardware? How good is the driver support for new hardware? Now I know there will be some minimal performance loss due to the VM's running on a headless hyper visor. 2. Will I be able to pass-through more than 1 GPU to per VM and run them in SLI or CROSSFIRE? 3. Will I be able to pass-through the NVMe PCIE SSD's to 1 VM and configure them in software RAID 0, Windows 10 Storage Pools. 4. Will I be able to pass-through the integrated audio card to the VM? 5. Will I be able to pass-through only USB controllers or just individual USB ports? 6. Will I be able to pass-through NIC ports to a VM? 7. Will unRAID support VM snapshots features at some point in the future? 8. Does unRAID create a physical file on the disk for the memory of each running VM? 9. Do I need a dedicated GPU or iGPU for the unRAID? Can't i just manage everything through SSH or the web interface and assign my GPU's for my gaming VM? 10. What are unRAID's actual spec requirements for the hyper visor. If I have an 4 core CPU and 8GB RAM do I need to leave 1 core and 1GB RAM unassigned for unRAID or will it intelligently handle the processing like ESXi does it for both memory and processing? 11. Will you add UEFI support? I tried running unRAID 6 from a USB 3 drive in a USB 3 port and it did not work. I had to use a USB 2 drive in the USB 3 port for it to work. 12. Can I just do the following... Linux - SSH 64GB Virtual Disk - Stored on the 128GB Samsung SM951 M.2 NVMe - 32GB RAM - 16 Cores - iNetwork Pass-Through Windows - Monitor/Mouse/Keyboard 64GB Virtual Disk - Stored on the 128GB Samsung SM951 M.2 NVMe - 32GB RAM - 16 Cores - 2 x PCIE SSD INTEL 750 Pass-Through - 2 x PCIE GPU PASCAL (SLI) or POLARIS (CROSSFIRE) Pass-Through - iAudio & iNetwork Pass-Through Many thanks for any help you may be able to provide.
