Bug 626008 – app-emulation/xen-tools patch to build sys-apps/pciutils if pcipassthru is enabled

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Richard Ostrow 2017-07-23 17:33:29 UTC]

The current ebuild(s) as written do not pull in required libraries for pci passthrough for xen. This does not trigger a compile error, and xen-tools will be installed without support for PCI passthrough. The attached patch modifies all current ebuilds to pull in sys-apps/pciutils (as a DEPEND) if the pcipassthru USE flag is enabled.

Reproducible: Always

Steps to Reproduce:
1. emerge xen-tools
2. configure xen to pass a PCI device to a DOM-U guest
3. start the DOM-U, and wait for it to timeout



Took me a full day to realize that xen-tools didn't support PCI passthrough... see the see also link.

xen-tools ebuild patch

Updates all current ebuilds to support a pcipassthru USE flag, causing xen-tools to DEPEND on sys-apps/pciutils, allowing pci passthrough to function under xen.
