- The Host devices tab gives a shut-off VM a PCI device of its host and takes it back; libvirt binds the device to vfio-pci when the VM starts and gives it back when it stops (managed). The VM's PCI devices are listed with whether the running VM and its next start have them. - A device is offered, and accepted on the server under the compute's claim, only when it is no bridge of any kind (bridge header, PCIe port, or of the bridge class: host bridge, LPC), the host has none of its own network interfaces, disks or graphics card on it (else: bind it to vfio-pci on the host first), no other VM names it, and every other endpoint of its IOMMU group is the VM's too or has no driver or vfio-pci and no other VM; bridges in the group stay with pcieport, and a member that cannot be read keeps the group. Nothing in the group is taken implicitly. - A snapshot revert checks the PCI devices of the snapshot with the same rules; migration and clones already leave host devices out. - The add forms of the tab load together, when the tab opens. |
