From 225166ea901f0532454ef771f5d6b1e8528c21bd Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Thu, 19 Nov 2015 17:11:08 +0100 Subject: [PATCH] libxl: correct bug in domain builder regarding page tables for pvh Commit 81a76e4b12961a9f54f5021809074196dfe6dbba ("libxc: rework of domain builder's page table handler") dropped a special case for pvh resulting in page tables being mapped read-only. This led to a panic of the domain in early boot. Correct this error.
