Please make it easier for new VMs to be able to talk/see to TrueNAS. As Tom said, TrueNAS is NAS first, so we usually want to be able to read/write some data that is on TrueNAS dataset(s) from inside VM, currently setting this is really cumbersome, because by default the newly created VM can't see/ping TrueNAS. Thanks 🙏

To have your virtual machine talk to the host is to configure a bridge on your network adapter. 20Gb/s on the virtual interface should be plenty of speed for your VM to communicate to the host.

Thanks for producing the best vids about truenas scale that I've seen. If I have one wish it would be to drill down more for us enthusiastic newbs who need a more step by step guide and explanations of all the features that you (and many KZfaqrs) skim over assuming prior knowledge. Of course you may not want to bore the already familiar but tutorial videos for beginners would be great. For example setup VM, Different use cases for clone, snapshot and replication. Off-site backups? A friend and I are trying to make 2 server to run VM game servers, one at each site. We'd like to build in some data resilience. We also hit the snag of the host/VM visibility so a guide for the work around would be great. Sorry for the big wish list but we hope you'll be our teacher on this. :)

@veritanuda Жыл бұрын

Just FYI the limitations in features are not part of KVM it can do both clustering and backing up of VMs. I am guessing who ever is working out the logic for the GUI hasn't figured out how to present that yet. But it is only a matter of time. As to VMs not accessing the host by default, that is definitely a feature, not a bug. As you alluded usually it is a separate VM and NAS and would always have some sort of credentials certificates between them. To access and NAS share though the VM you should just add the local share the VMs pool instead. It would be redundant to rely on networking protocols when you access the raw dataset locally anyway. Good video though and I am happy to see Scale coming on with leaps and bounds. Cheers

hey tom, thanks for that video :) another note on truenas scale that might be of interest for anyone: it seems like power saving options do not work very well if you transfer your installation to a different system (mainboard / cpu upgrade). i did have to reinstall the system and restore config to get all cpu c-states to work etc. just a heads up :)

@terrysimons Жыл бұрын

They're using qemu under the hood, and qemu requires a tun/tap interface to interact with the host, and because of that, it's required to bridge that interface to any networks that might be natively on the host. TrueNAS probably needs to build some infrastructure around their qemu support to enable this to work smoothly.

I've tried to think of usecases where it makes sense to run a VM on the NAS, and my best use casse really is A) Very small 1-25 employee businesses that only need a basic DC + File share, or B) Read-only DC/DNS for a remote site (and it's offsite storage), or C) A jump client to be able to perform management on some of the other infrastructure. Of course there are other strategies, but I know clients for some of the sites I help manage that would sufficiently run, or run better with, the VM running directly on the box that hosts a more robust storage box vs Storage + Vm host + networking to make that work well.

the networking issues stems from a similar sriov pcie device problem with net ROM options and what is known as nic promiscuous mode. Not all nic(Netwrok Cards) support this mode, with short in short can support vlan bridge traffic to host. simalr with dockers and mac_vlan network setps where host traffic and docker traffic for "security" are designed as such. But i agree there should be a checkbox to software or have host traffic accessible without the need of passing a nic card to the VM.

@harrytsang1501 8 ай бұрын

I'm speaking from experiences with proxmox and see if you can find the equivalent since it's just KVM under the hood. I understand that as you'd want WSL2 in a Windows guest - Intel needs CPU model set to Skylake-Client-noTSX-IBRS, with args '+vmx,-hypervisor' - AMD needs host with args '+svm,-hypervisor' Enabling hyper v makes everything in guest windows 12% slower because the whole windows became a guest OS

I find the CPU settings confusing. I run Scale on a Poweredge R420 which is a dual CPU system. If I want to give a VM access two 2 cores on each of the 2 CPUs what do I set those settings to? 4, 2 and 2? The little help bubbles aren't very helpful in my opinion. In proxmox I just set the number of sockets and cores then enable NUMA. Also how are you supposed to backup these VMs?

Hello! Could somebody please point me to a tutorial or video on how to give a VM (Ubuntu) an IP address outside of my DHCP range? I have two NICs in my Truenas System. One gets its IP adress via DHCP from my router (192.168...) and the other is configured with a static IP (10.10.0...). I'd like to have my VM an address from the 10.10... range, but even if I attach the second NIC in "Devices" to it, it will always get an IP of 192.168....X.

Every TrueNAS SCALE tutorial I find on VM hosting glosses over networking. I have no issues creating the VMs but getting them on the network is an entirely different proposition. I create linux VMs and am unable to update repositories or host services because the procedure you provided (and many other KZfaq hosts) do not go over network setup. A VM that is completely offline has limited value. Do you have a video on getting TrueNAS VMs on your local network?

@tedcalouri2694 3 ай бұрын

I contacted TrueNAS scale support. While TrueNAS scale VMs are able to interact with the NAS storage itself, they have not validated a usecase where VMs hosted on the NAS are accessible by other systems on the LAN. You cannot for example host a simple webserver for clients on your LAN.. How is that valuable as a VM host?
