[PATCH][3/3] XenAPI: Example Scripts for PCI Assignment

[Yosuke Iwamatsu <y-iwamatsu@ab.jp.nec.com>]

[-- Attachment #1: Type: text/plain, Size: 309 bytes --]

These attachments are examples for pci assignment via xen-api.

ppci_get_record.py: demonstrates physical pci information acquisition.
dpci_create.py: adds a pci device to a domain.
dpci_destroy.py: removes a pci device from a domain.
