Subject: [PATCH V3] libxl: Increase device model startup timeout to 1min.
Date: Tue, 7 Jul 2015 16:09:13 +0100 [thread overview]
Message-ID: <1436281753-19534-1-git-send-email-anthony.perard@citrix.com> (raw)
In-Reply-To: <21915.58620.948343.728555@mariner.uk.xensource.com>
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.
