Subject: [PATCH 3/6] libxl: actually print an error when execve (in libxl__exec) fails
Date: Tue, 1 Feb 2011 18:24:59 +0000 [thread overview]
Message-ID: <1296584702-20138-4-git-send-email-ian.jackson@eu.citrix.com> (raw)
In-Reply-To: <1296584702-20138-3-git-send-email-ian.jackson@eu.citrix.com>
The header comment says libxl__exec logs errors. So it should do so.
