Name:

Give the VM a name (e.g. OpenELEC Family Room, OpenELEC Theatre, OpenELEC)

Description:

Give the VM a brief description (optional field).

OpenELEC Version:

Select which OpenELEC version to download or use for this VM

Download Folder:

Choose a folder where the OpenELEC image will downloaded to
Config Folder:

Choose a folder or type in a new name off of an existing folder to specify where OpenELEC will save configuration files. If you create multiple OpenELEC VMs, these Config Folders must be unique for each instance.

CPU Mode:

There are two CPU modes available to choose:

Host Passthrough
With this mode, the CPU visible to the guest should be exactly the same as the host CPU even in the aspects that libvirt does not understand. For the best possible performance, use this setting.

Emulated
If you are having difficulties with Host Passthrough mode, you can try the emulated mode which doesn't expose the guest to host-based CPU features. This may impact the performance of your VM.

Logical CPUs:

The number of logical CPUs in your system is determined by multiplying the number of CPU cores on your processor(s) by the number of threads.

Select which logical CPUs you wish to allow your VM to use. (minimum 1).

Initial Memory: Max Memory:

Select how much memory to allocate to the VM at boot.

For VMs where no PCI devices are being passed through (GPUs, sound, etc.), you can set different values to initial and max memory to allow for memory ballooning. If you are passing through a PCI device, only the initial memory value is used and the max memory value is ignored. For more information on KVM memory ballooning, see here.

Machine:

The machine type option primarily affects the success some users may have with various hardware and GPU pass through. For more information on the various QEMU machine types, see these links:

http://wiki.qemu.org/Documentation/Platforms/PC
http://wiki.qemu.org/Features/Q35

As a rule of thumb, try to get your configuration working with i440fx first and if that fails, try adjusting to Q35 to see if that changes anything.

BIOS:

SeaBIOS
is the default virtual BIOS used to create virtual machines and is compatible with all guest operating systems (Windows, Linux, etc.).

OVMF
(Open Virtual Machine Firmware) adds support for booting VMs using UEFI, but virtual machine guests must also support UEFI. Assigning graphics devices to a OVMF-based virtual machine requires that the graphics device also support UEFI.

Once a VM is created this setting cannot be adjusted.

$arrGPU) { $strLabel = ($i > 0) ? appendOrdinalSuffix($i + 1) : ''; ?>
Graphics Card:

Graphics Card
If you wish to assign a graphics card to the VM, select it from this list.

1) { ?>

Additional devices can be added/removed by clicking the symbols to the left.

$arrAudio) { $strLabel = ($i > 0) ? appendOrdinalSuffix($i + 1) : ''; ?>
Sound Card:

Select a sound device to assign to your VM. Most modern GPUs have a built-in audio device, but you can also select the on-board audio device(s) if present.

1) { ?>

Additional devices can be added/removed by clicking the symbols to the left.

$arrNic) { $strLabel = ($i > 0) ? appendOrdinalSuffix($i + 1) : ''; ?>
Network MAC:
Network Bridge:

Network MAC
By default, a random MAC address will be assigned here that conforms to the standards for virtual network interface controllers. You can manually adjust this if desired.

Network Bridge
The default libvirt managed network bridge (virbr0) will be used, otherwise you may specify an alternative name for a private network bridge to the host.

Additional devices can be added/removed by clicking the symbols to the left.

USB Devices:
$arrDev) { ?>
None available"; } ?>

If you wish to assign any USB devices to your guest, you can select them from this list.
NOTE: USB hotplug support is not yet implemented, so devices must be attached before the VM is started to use them.

USB Mode:

USB Mode
Select the USB Mode to emulate.

Other PCI Devices:
$arrDev) { $extra = ''; if (count(array_filter($arrConfig['pci'], function($arr) use ($arrDev) { return ($arr['id'] == $arrDev['id']); }))) { $extra .= ' checked="checked"'; } else if (!in_array($arrDev['driver'], ['pci-stub', 'vfio-pci'])) { //$extra .= ' disabled="disabled"'; continue; } $intAvailableOtherPCIDevices++; ?>
None available"; } ?>

If you wish to assign any other PCI devices to your guest, you can select them from this list.
