| + | ===== Build and Install ZFS on Linux (deb method) ===== | ||
| + | * Download current release from [[https://github.com/zfsonlinux/zfs/releases]]. You will need **spl-x.x.x.x.tar.gz** and **zfs-x.x.x.x.tar.gz** | ||

| + | ===== USB Passthough ===== | ||
| + | * If you are passing a physical video card to a VM, you will need to also pass usb input devices to the VM since the VM will not have a SDL or Spice virtual display. | ||
| + | * This is done through USB passthrough. | ||
| + | * To find the USB id's to pass through run <file>lsusb | grep -v "root hub"</file> | ||
| + | * This will give you something like this<file>Bus 005 Device 002: ID 046b:ff10 American Megatrends, Inc. Virtual Keyboard and Mouse | ||
| + | Bus 003 Device 003: ID 0557:2205 ATEN International Co., Ltd | ||
| + | Bus 003 Device 002: ID 0451:2046 Texas Instruments, Inc. TUSB2046 Hub</file> | ||
| + | * What we want is the hexadecimal ID **ffff:ffff** | ||
| + | * then this to pass the usb device to the vm<file>-usbdevice host:ffff:ffff</file> | ||
| ===== Example kvm script ===== | ===== Example kvm script ===== | ||
