From 9acfbe14d7261b03e3b3f4dc3c850ba2a7093e1f Mon Sep 17 00:00:00 2001 From: Anthony PERARD Date: Tue, 7 Jul 2015 16:09:13 +0100 Subject: [PATCH] libxl: Increase device model startup timeout to 1min. On a busy host, QEMU may take more than 10s to load and start. This is likely due to a bug in Linux where the I/O subsystem sometime produce high latency under load and result in QEMU taking a long time to load every single dynamic libraries.
