Console/channel devices have their pty devices assigned when the emulator is actually started. If time is spent in guest preparation, someone attempts to open the console/channel, the libvirt crashes in virChrdevLockFilePath(). The patch attempts to fix the crash by adding a check before attempting to open. Signed-off-by: Shivaprasad G Bhat <sbhat@linux.vnet.ibm.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
