When building Genode on a Linux system running in a Xen Dom0, the 'xen'
run target can run a Genode scenario in a Xen DomU.
Usage: in build/x86_*/etc/build.conf, define:
RUN_OPT = --include boot_dir/$(KERNEL) --include image/iso --include power_on/xen --include log/xen --include power_off/xen
The Xen DomU runs in HVM mode and loads Genode from an ISO image. Serial
log output is printed to the console and graphical output is shown in an
SDL window.
The Xen DomU ist managed using the 'xl' command line tool and it is
possible to add configuration options in the 'xen_args' variable in a run
script. Common options are:
- disabling the graphical output:
append xen_args { sdl="0" }
- configuring a network device:
append xen_args { vif=\["model=e1000,mac=02:00:00:00:01:01,bridge=xenbr0"\] }
- configuring USB input devices:
append xen_args { usbdevice=\["mouse","keyboard"\] }
Note: the 'xl' tool requires super-user permissions and interactive
password input can be troublesome in combination with 'expect' and is not
practical for automatic tests. For this reason, the current implementation
assumes that no password input is needed when running 'sudo xl', which can
be achieved by creating a file '/etc/sudoers.d/xl' with the content
'user ALL=(root) NOPASSWD: /usr/sbin/xl'
(where 'user' is the Linux user name).
Fixes#2504
The new parameter specifies the additional timeout duration in seconds
which is incurred by AMT log processing, e.g. time spent waiting for the
system to boot.
The run plugin is not generic and works for NETIO4/NETIO230 powerplugs
only. Further, this opens the path for other vendor-specific powerplug
plugins.
Note, the plugin parameter for the addressed powerplug was renamed to
--power-on-netio-host resp.
--power-off-netio-host
While booting up, some devices send garbage over the serial connection.
This can result in an unexpected EOF event within expect(1). A filter
program may be specified with '--log-serial-filter' to circumvent this
problem. Then, the output of the serial program is piped through
the filter, which may sanitize the character stream.
Fixes#1395.
