This patch adds support for the newly introduced
VIR_DOMAIN_CONSOLE_FORCE and VIR_DOMAIN_CONSOLE_SAFE flags. The console
command now has an optional parameter --force that specifies that the
user wants to forcibly interrupt an ongoing console session and create
a new one. Flag --safe requests that the console should be opened only
if the hypervisor driver supports safe console handling.
The behaviour to this point was that the daemon opened two streams to
the console, that competed for data from the pipe, and the result was
that both of the consoles ended up scrambled.
This patch doesn't modify operation of other commands dealing with
console connections (start, create) as those open connections to newly
started domains making it virtually impossible for another client to race
for the console and steal it.
* tools/console.c:
- add support for flag passthrough
* tools/console.h:
- modify function prototypes to match impl.
* tools/virsh.c:
- add flag --force for the console command
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.
