Unraid - USB Problem

[Bl00dgod]

the machine is running but there are some problems with the USB peripherals

its not 30grand or as powerful as the rig linus did but a good start 

 

after connecting the peripherals on the io panel and whenever its set to  mouse1 to vm 1  and  mouse2 to vm 2  etc in unraid to the specific machine its changing the guid of it

after changing the XML to the correct "mouse" guid it the mouse-guid instantly changes to something else

some tinkering helps and it runs well until you restart the vm´s and the mouse gets another id again

 

 

and is there a way to passthrough different usb hubs to each vm? 

was linus able to access the display usb hub?

summoning @nicklmg that maybe knows, or knows someone that knows it 

 

can anyone help with this issues?

 

thanks in advance

You can't hotplug usb devices, unless you get a pcie to usb adapter and give that to a vm.

 

Id also highly suggest you move away from unraid and use something like esxi, proxmox, xen, or ovirt. THey have much better support and are much more trusted.

why did linus use unraid then instead of all those others?

all pci slots are used

Because he was sponsored.

 

Id suggest you stay away from using vm's like this. If you want a multi use vm solution, buy thin clients for every user.

we already got the rig and now we want to use it, no more thin clients

we ´re using the free limetech unraid version

the 7gamers 1rig was a nice inspiration but some important config informations arent told in the video

but thats exactly how we want to use it, 1 rig and seperate vm on it

Problem is that thats not really a supported config. Id stay away form that and either get thinclients, or separate systems.

do those solutions do gpu passtrough?

Yep they all do, and esxi and xen do it better as you can give one gpu to multiple vms.

i should maybe mess with proxmox again then sometime.

 

although, how would one gpu to multiple vms even work?

Nvidia has grid that lets you use all the normal gpu drivers and it splits up the cores and vram. You can also split it in solfware and have the hypervisor pass the calls through, but your limited to what ever drivers the hypervisor makes, currently esxi only supports directx 9 with this mode.

 

Id personally mess with xen and esxi if you want to learn about commerical hypervisor

but the big thing linus uses unraid for is that the gpu is hooked up to the VM as if bare metal.

That also works fine, but doesn't make sense for a buiness desktop environment as needing one gpu for every user, when most of the time the usage is under 10%

seems like if we manage to route the riser cable through to the slots between the cards it should run fine

waiting for the pci-e usb hubs to arrive but the defect/ faulty we tried was working and got detectet

so this way everyone still gets seperate USB slots delivered to the VMs

 

rig update with pci/m2 riser cables
