From f509e85f7178c7c2e30bddf5778ad278ac0fbd91 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Wed, 4 Jan 2012 15:11:02 -0500 Subject: [PATCH] xen/pciback: Fix "device has been assigned to X domain!" warning The full warning is: "pciback 0000:05:00.0: device has been assigned to 2 domain! Over-writting the ownership, but beware." which is correct - the previous domain that was using the device forgot to unregister the ownership. This patch fixes this by calling the unregister ownership function when the PCI device is relinquished from the guest domain.
