Hi Carlos,
How are you running it? The 'make run' for Xen will generate a skeleton .xl file,
which you then run yourself using 'xl console -c <file>.xl'. That should
attach you to the Xen console, where you can see the hello world output.
I think you mean "xl create -c <file.xl>" :)
Just in case you see nothing on the console (because of an early exit,
often caused by forgetting to attach a disk), start the VM paused with:
xl create -c -p <xl config file>
and then unpause it from another terminal
xl unpause -p <VM name>
Cheers,
Dave

Hi,
Doing a clean installation and changing the ownership and permissions has
worked, now I am able to configure and build a Xen VM (I can see the files
generated), however when running the it does not generate the main.xl Xen
configuration file (xen-utils-common are installed) so I cannot see the console
commands generated by the for loop.
I would appreciate your help, thanks in advance.
Kind regards
Carlos Oviedo

hmm-- there might be some confusion here.
the "--unix" and "--xen" flags are to do with the target being built, not the
platform being built on. on a vanilla ubuntu platform i think you should be able to use either
(though you might need to apt-get install a few extra packages for --xen, i can't recall; the
install/hello-world pages on openmirage.org should say).
given the permission denied error below for the lock file and the other
permission errors you were having, i'd strongly suspect it's ownership and
permission issues on files due to using sudo on some commands but not others.
(though i have to admit i've never come across the ibus stuff before!)
*assuming you've nothing special installed and you know this won't break anything* and that your
user and group are both called "carlos" i'd try something like "sudo chown -R
carlos:carlos /home/carlos".
if things ever get too confused, you can always "rm -rf ~/.opam" to completely
nuke opam state and start again.
all i can suggest at this point about the ibus thing is to use google... :)
(and possibly replace ubuntu with debian wheezy...)

Thanks Narayana,
I have tried as suggested, first removing the mirage-xen and mirage-console-xen, however,
when I run "mirage configure --unix" I got the following error:
carlos@:~/mirage/mirage-skeleton/console$ mirage configure --unix

console Fatal error:

Then I tried "sudo mirage configure --unix" and it only opens an empty graphic
console and the main and Makefile files are not generated.
Alternatively, I manually installed the OPAM packages (mirage-console-unix and
mirage-unix), but still I am stuck.
I would appreciate your help, thanks in advance.
Kind regards
Carlos Oviedo

HI carlos,
You have to specify unix as your installed mirage on linux to
work properly as far as i know
sudo mirage configure --unix i mean other than xen option .i think
there are two options one is unix other is xen .so use --unix to work for your
system.

Hi,
I would appreciate your help on the following issue.
I recently installed Mirage using OPAM following the instructions as provided in the
documentation available at www.openmirage.com<http://www.openmirage.com> (I am on a
64-bit Linux-Ubuntu machine). However, I cannot complete the Hello World example given there. I
think the problem starts with the command "mirage configure --xen", the error
encountered is as follows:
-carlos@:~/mirage/mirage-skeleton/console$ sudo mirage configure --xen
-(mirage:4984): IBUS-WARNING **: The owner of /home/carlos/.config/ibus/bus is
not root!
An empty graphic console is shown and the files main.ml<http://main.ml> and
Makefile are not generated.
What I saw is that the "mirage configure --xen" command executes the installation of
"mirage-console-xen" and "mirage-xen" which I have installed manually through the "opam
install" command (current versions are 1.0.2 and 1.1.1, respectively), however, the problem persists.
I changed the permissions to root of the file /home/carlos/.config/ibus/bus and try again
"sudo mirage configure --xen", although this time there is no error messages I still
get an empty graphic console and files main.ml<http://main.ml> and Makefile are not
generated.
Thanks in advance.
