From f366cfed62969ae3ebd34d866a40ecdb01c95519 Mon Sep 17 00:00:00 2001 From: Pavel Hrdina Date: Fri, 21 Jul 2017 15:09:54 +0200 Subject: [PATCH] qemu: pass only host arch instead of the whole virCaps This is a preparation for following patches where we switch to virFileCache for QEMU capabilities cache The host arch will always remain the same but virCaps may change. Now the host arch is stored while creating new qemu capabilities cache. It removes the need to pass virCaps into virQEMUCapsCache*() functions.
