Is Proxmox 2.1 compatible with USB3 PCI-Express cards?
I'd like to backup to an external USB drive using USB3 but wanted to make sure it supports it before buying the USB3 card.

Thanks!
 
I wanted to update this. I bought a StarTech 2 Port SuperSpeed USB 3.0 PCI Express Card with SATA Power (Part # PEXUSB3S22) and it worked right away with Proxmox 2.1. I have a USB 3 external drive attached and set KVMs to backup to it using LZO compression. I get an average of 60MiB/s.

Update: I just ran a snapshop backup (LZO) of Windows server 2008 and the archive size was 9.76GB and took 00:39 minutes at 129.78MiB/s.

Hi guys,

i also tried to pass a usb 3.0 HDD to a kvm guest. usb 2.0 is working, 3.0 no way. Im a little bit puzzled about this link http://www.linux-kvm.com/content/qemu-kvm-11-adds-experimental-support-usb-30. For @bhennigar it seems to work flawlessly ... Can you give me a stand on this so I can dig further?

Thanks!

I'm not using USB passthrough with my USB 3 card. I'm using it to mount an external hard drive and using it as a backup target for virtual hosts.

That's what I had in mind as well. Would you mind showing "lsusb" "lsusb -t" and "lsmod" and "dmesg | grep xhci"" ? I'd like to see what I'm missing..
 
Hope this helps!

Thanks, appreciate it.. reviewing..

One more thing.. my PCI-E card is on 08:00.0, change as appropriate for you.. I suspect we're running the same card, but curious what your output on this looks like:

You do have a power cable going to the USB3 card correct?
