qemu: PCI device, disk and host network hot-add / hot-remove (Marcelo Tosatti)
Add monitor command to hot-add PCI devices (nic and storage).
Syntax is:
pci_add pci_addr=[[<domain>:]<bus>:]<slot> nic|storage params
It returns the domain, bus and slot for the newly added device on success.
It is possible to attach a disk to a device after PCI initialization via
the drive_add command. If so, a manual scan of the SCSI bus on the guest
is necessary.
Save QEMUMachine necessary for drive_init.
Add monitor command to hot-remove devices, remove device data on _EJ0 notification.
