mikeyosm Posted September 25, 2020 Share Posted September 25, 2020 Hi team UNRAID Whilst I'm waiting for 6.9 final to release (soon i hope), I thought I'd look at ways of speeding up VM disks on my 3Gbps NVME drive and exposing shares set up in UNRAID so that I could access them directly from a VM instead of using the 1GBps/10Gbps virtual NIC. Research led me to this article https://www.reddit.com/r/VFIO/comments/eryb71/best_storage_for_vfiokvmqemu_experiment_results/ and https://virtio-fs.gitlab.io/howto-qemu.html I'm interested to know if virtio-fs can be made available in UNRAID so that shares can be access directly from a VM? 1 Quote Link to comment

benfishbus Posted March 28, 2021 Share Posted March 28, 2021 Seeing that we are now at 6.9.1, I would like to have this working, too. I've not gone as far as either of you. I'm accustomed to setting up 9p, which just isn't cutting it, and am very interested in the more direct(?) virtio-fs driver. Quote Link to comment
pk1057 Posted May 10, 2021 Share Posted May 10, 2021 With 6.9.2 still the same error Quote Link to comment
pants Posted May 25, 2021 Share Posted May 25, 2021 I was able to get virtio-fs working on Unraid 6.9.2. See this thread for details: Quote Link to comment
