Instance Method Details
#add(device, opts = {}) ⇒ HostDevice
Attach target device to given virtual machine.
Example:
POST /ovirt-engine/api/vms/123/hostdevices
With request body of type HostDevice, for example
<host_device id="123" />
Note
|
A necessary precondition for a successful host device attachment is that the virtual machine must be pinned to exactly one host. The device ID is then taken relative to this host. |
Note
|
Attachment of a PCI device that is part of a bigger IOMMU group will result in attachment of the remaining
devices from that IOMMU group as "placeholders". These devices are then identified using the placeholder
attribute of the HostDevice type set to true .
|
In case you want attach a device that already serves as an IOMMU placeholder, simply issue an explicit Add operation
for it, and its placeholder
flag will be cleared, and the device will be accessible to the virtual machine.
