Re: [MirageOS-devel] Hello Mirage World

[Luis Oviedo García <psxlco@xxxxxxxxxxxxxxxx>]

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...)
