@bowerandy I did have the freezing problem when I first started trying this I can’t remember specifically what the solution was but some of the things I changed were bios related to APCI and power management. I’m running a relatively old motherboard ASUS z10pe-d16-ws though, I haven’t upgrade because it lets me play with 512GB ram and 2x 22 core CPU’s. I did notice a huge impact moving from legacy booting to UEFI, also another adventure was figuring out that windows VM’s played much better running as OVMF especially when passing GPU’s or other PCIE devices. I spent years fine tuning unraid from 5.x-6.x and never really got the same performance:headache ratio with proxmox. It worked out of the box minus minor tweaks. I’m curious as to what your bootflags for grub are and more details about you system and configuration. I included some pictures so you can see how I’m passing my usb card to the gaming vm.

this worked for me, I no longer use unraid but I tested it with proxmox 6.1-3 and I passed through a Fresco Logic FL1000 USB 3.0 Host Controller to my gaming vm and was able to enable Oculus Link for my Quest. No problemo

I have actually moved away from unraid to proxmox due to native iscsi and NFS support. Miss unraid but proxmox fills my needs

This should be taken care of within the rules try this maybe? https://www.reddit.com/r/unRAID/comments/83ngly/docker_container_network_setting/

putting this here for future reference https://www.kernel.org/doc/Documentation/vm/hugetlbpage.txt

+1 my reason is that I need the performance benefits from it being natively baked in vs emulating it from within a vm. Some of my use cases are very dependent on hardware accelerated iscsi and emulation reduces the performance vastly in high bandwidth low latency scenarios

Thank you for the great information! I thought it was something deeper like a kernel option during compiling or something, I didn’t realize it was enabled already right out of the box! Is there any specific documentation about hugepages and VM tuning? Is it specific to OVMF or seabios, etc?

I would like to see a PxE boot option for unraid

I'm running supermicro SYS-4029GP-TRT2 dual cpu system with 512GB ram and it runs around 32 virtual machines and have been dealing with random sluggish performance, i'm assuming that this due to transparent pages? Things work fine when I step down to around 32GB ram and turn off some of the VM's. Each cpu is a E5-2699 V4 @ 22 cores so 44 total for the system Each VM is running with 16GB and 1 vcpu and its correct hyper thread Is there a way to turn on or enable huge pages or does it require a custom kernel build? Currently running Unraid 6.8.2 Stable and 6.5.1 Stable Experiencing this exact issue from this linus video but the correction and fix was provided by the unraid team and doesn't appear to be available publicly? https://youtu.be/1yFQd4MaKK0?t=554 Here’s a pic for anyone interested in my build project Replaced this one Thanks!

Anyone done this with E5-2696V4 Cpus? I have 2 cpus on a ASUS Z10PE-D16. I want to pin core 0 and 1 from cpu one, and core 0 (44?) and 1 (45?) from cpu two. Ideally this should give 4 cores to a VM running at 3.7Ghz on turbo?
