2 On the Virtual Hardware tab, add a SCSI device to the virtual machine.
Client Steps
vSphere Client Click the Add New Device button and select SCSI Device from the drop-down
menu.
vSphere Web Client a Select SCSI Device from the New device drop-down menu at the bottom of
the wizard.
b Click Add.
The SCSI device appears in the Virtual Hardware devices list.
3 On the Virtual Hardware tab, expand SCSI Device and configure the SCSI device or change the
default configuration settings.
a From the Connection drop-down menu, select the physical SCSI device to connect to.
b (Optional) From the Virtual Device Node drop-down menu, select the virtual device node.
4 Click OK.
The virtual machine can access the device.
Add a PCI Device
vSphere DirectPath I/O allows a guest operating system on a virtual machine to directly access physical
PCI and PCIe devices connected to a host. This action gives you direct access to devices such as high-
performance graphics or sound cards. You can connect each virtual machine to up to six PCI devices.
You configure PCI devices on the host to make them available for passthrough to a virtual machine. See
the vSphere Networking documentation. However, PCI passthroughs should not be enabled for ESXi
hosts that are configured to boot from USB devices.
When PCI vSphere DirectPath I/O devices are available to a virtual machine, you cannot suspend,
migrate with vMotion, or take or restore Snapshots of such virtual machines.
Prerequisites
n
To use DirectPath, verify that the host has Intel Virtualization Technology for Directed I/O (VT-d) or
AMD I/O Virtualization Technology (IOMMU) enabled in the BIOS.
n
Verify that the PCI devices are connected to the host and marked as available for passthrough.
Disable the USB controller for passthrough if your ESXi host is configured to boot from a USB device,
or if the active coredump partition is configured to be on a USB device or SD cards connected
through USB channels. VMware does not support USB controller passthrough for ESXi hosts that
boot from USB devices or SD cards connected through USB channels or if the active coredump
partition is configured to be on a USB device or SD card connected through USB channels. For more
information, see http://kb.vmware.com/kb/1021345.
n
Verify that the virtual machine is compatible with ESXi 4.x and later.
Procedure
1 Right-click a virtual machine in the inventory and select Edit Settings.
