To allow devices to be hot(un-)plugged it is neccessary to ensure
they all have a unique device aliases. This fixes the hotplug
methods to assign device aliases before invoking the monitor
commands which need them
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Expose methods
for assigning device aliases for disks, host devices and
controllers
* src/qemu/qemu_driver.c: Assign device aliases when hotplugging
all types of device
* tests/qemuxml2argvdata/qemuxml2argv-hostdev-pci-address-device.args,
tests/qemuxml2argvdata/qemuxml2argv-hostdev-usb-address-device.args:
Update for changed hostdev naming scheme
Replace
-balloon virtio
With
-device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3
This allows it to get correct assigned PCI address as declared in
previous patch
* src/qemu/qemu_conf.c: Convert Virtio ballon to -device and
give it an explicit PCI address
* tests/qemuxml2argvdata/qemuxml2argv-*args: Add in virtio balloon
where appropriate
The old syntax was
-usbdevice host:PRODUCT:VENDOR
Or
-usbdevice host:BUS.DEV
The new syntax is
-device usb-host,product=PRODUCT,vendor=VENDOR
Or
-device usb-host,hostbus=BUS,hostaddr=DEV
