Change in vdsm[master]: vdsm: add support for hot(un)plug of pci-passthrough devices
by mpoledni＠redhat.com 19 Oct '15

19 Oct '15

Martin Polednik has uploaded a new change for review. Change subject: vdsm: add support for hot(un)plug of pci-passthrough devices ...................................................................... vdsm: add support for hot(un)plug of pci-passthrough devices Hot(un)plug ability for pci-passthrough devices is extremely important in order to allow for hotunplugging/migrating/hotplugging workflow as VM cannot be migrated with pci device attached. This patch implements the ability adding new API verbs: hotplugHostdev and hotunplugHostdev, which attempts to append/remove the device from domain XML and reports back the state.
