Configuring USB Devices Passthrough from VMWare ESXi to a Virtual Machine

On your VMWare ESXi host, you possibly can redirect an hooked up native USB machine/flash drive/disk contained in the digital machine. This technology is known as USB Passthrough and obtainable beginning from ESXi Four.1.

Suppose, our activity is to redirect an exterior USB three.zero drive regionally related to the ESXi 6.7 host into a digital machine. We want to entry a drive to shortly copy information instantly from the VM to a separate USB drive.

VMWare USB Passthrough

The Passthrough mode permits to redirect a bodily machine related to an ESXi host instantly to the visitor OS of a digital machine. In the Passthrough mode you possibly can grant a digital machine the direct entry to a USB drive, a modem or a PCI/USB controller.

To redirect a USB machine in ESXi, you will want some most important elements:

  • Arbitrator is a separate service on an ESXi host that scans related bodily USB units, routes USB machine site visitors between a host and a VM, and controls entry to a machine (just one VM could use a related USB machine). A USB arbitrator can monitor up to 15 USB controllers concurrently.
  • USB controllers — a uSB controller should be put in each on a bodily host and on a digital machine.

To set up a USB controller for a VM on VMWare ESXi, open the VM settings and add a new machine — a USB controller. When including a USB controller, choose its kind:

  • USB 2.zero (EHCI+UHCI) – a controller supporting USB 2.zero and USB 1.1 units;
  • USB three.zero (xHCI) – helps quick USB three.zero units, requires digital model eight or increased.

USB three.zero mode is accessible beginning from vSphere 5.5 patch three. To assist it, an xHCI controller should be working in a visitor OS. Windows eight.1/Windows Server 2012 R2 and Linux with the kernel model 2.6.35 or newer are supported as a visitor OS.

Passthrough a USB Device to ESXi VM

In the native USB Passthrough mode, you possibly can join a bodily USB machine from a host to a VMWare digital machine.

The most important necessities and restrictions of this redirection technique:

  • Virtual Hardware 7.zero or newer;
  • You can present direct entry to a USB machine for one VM solely;
  • The most variety of redirected USB units for a VM is 20;
  • A VM boot from the hooked up USB machine isn’t supported.

After including a digital USB controller for a VM, you possibly can redirect a USB drive related to the host:

  1. Add a new Host USB machine within the VM settings and click on  Add;
  2. Select a related USB machine from a dropdown checklist to add it;
  3. To allow vMotion assist for a VM with a related bodily USB drive, test the Support vMotion whereas machine is related choice;Passthrough a USB flash drive to VM from Vmware ESXi host
  4. Then the USB drive will seem within the visitor OS of the digital machine.
There are some vMotion restrictions for VMs with a redirected USB drive:

  • You can not cease or pause a VM. If you activate the machine, you need to manually migrate it to the host the USB machine is related to;
  • DPM mode isn’t supported, since vCenter can shutdown a host with the related USB machine to save energy;
  • ESXi hosts with the VM and a bodily USB machine should be accessible through vmk0 over TCP Port 902.

If when including a new USB machine a vSphere shopper exhibits a message that no USB units has been discovered (No obtainable USB units), it implies that VMWare doesn’t assist your USB drive for redirecting within the USB passthrough mode. You can discover the checklist of suitable USB units on the official VMWare web site (the checklist isn’t lengthy). Check the “USB Devices examined for Passthrough from an ESXi Host to a Virtual Machine in ESXi 6.7” part within the article https://kb.vmware.com/s/article/1021345.

In this case you possibly can redirect the entire USB controller to a VM from the ESXi host.

VMware PCI Passthrough (VMDirectPath): Redirect a USB Controller to a VM

Another, much less handy technique to present entry to a bodily USB machine from a VM is to redirect the entire USB controller from the ESXi host. This mode is known as VMDirectPath. To use it, your server chipset should assist Intel Directed I/O or AMD I/O Virtualization Technology (AMD IOMMU), and this mode is enabled within the BIOS/UEFI settings.

If just one USB controller is put in on a server and also you redirect it to a VM, you gained’t have the option to use USB units related to your host regionally (keyboard, mouse). In this case, it’s higher to add an extra PCI USB controller to the server.

If a host has a number of USB controllers, you possibly can determine a related USB machine and a controller quantity by way of the ESXi shell. To show the checklist of USB units:

# lsusb -v | grep -e Bus -e iSerial

Find the road associated to the USB drive within the output. For instance:

Bus 002 Device 003: ID 0280:a00c Toshiba America Info. Systems, Inc.

Then determine a root hub and its iSerial by the controller quantity (Bus02, on this case):

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation three.zero root hub
iSerial                 1 0000:00:1D.zero
If you don’t see your USB drive, attempt to disconnect it bodily and join it once more. See the vmkernel.log to be taught if USB Arbitrator has detected your drive:

tail -f /var/log/vmkernel.log | grep -i USB

If the USB drive isn’t detected by your ESXi host, make it possible for the usbarbitrator service is working:

#chkconfig usbarbitrator --list

So we’ve got acquired the variety of the USB controller to be redirected to the VM.

  1. To redirect a bodily USB controller, choose the ESXi host your VM is working on and go to  Manage -> Settings -> PCI Devices -> Edit;
  2. In the checklist of PCI units choose the required USB controller by its ID (in my instance, it’s 00:1D.zero, the controller is known as C610/X99 sequence chipset USB Enhanced Host Controller #1 Intel Corporation);
  3. The standing of the USB controller should change from Unavailable (This machine isn’t at the moment obtainable for VMs to use) to Available (This machine obtainable for VMs to use). Click OK; VMware PCI Passthrough (VMDirectPath) for USB device
  4. To save the adjustments, restart your ESXi host;
  5. After booting the host, flip your VM off and add a new machine (New Device -> PCI Device -> Add). Select your USB controller within the dropdown checklist (for instance, 0000:00:1D| Intel Corporation USB Chipset…);

    If when including a PCI machine the next message seems within the VM settings: “Warning: The VM is not going to energy on till its reminiscence reservation equals its reminiscence measurement”, reserve some RAM in your VM.

  6. Power on the VM on and make it possible for the USB drive has appeared within the visitor OS. In my case, the related USB drive “Toshiba External USB three.zero USB Device” has appeared within the visitor Windows Server 2012 R2. redirect an external usb drive from esxi to VM

In the VMDirectPath mode, you possibly can redirect up to two bodily PCI units to a VM.

There are some restrictions on a VM with a redirected PCI machine: you can’t pause a VM (Suspend), carry out vMotion to one other host (it’s logical, since you’re sure to a bodily controller) or create snapshots.
