Hello, I am trying to create a VM using puppet and vmbuilder. I''ve got
the following declaration (now very simplified):
define virtual_machine ($ip) {
exec {"create_vm_${name}":
command => "/usr/bin/vmbuilder kvm ubuntu -d CNDR -v -m 512 --
cpus=1 --rootsize=5096",
unless => "/usr/bin/test -d /var/lib/kvm/${name}",
}
}
When I run puppetd in debugging mode on the client I get this:
debug: //Node[10.0.0.165]/Virtual_machine[anewvm]/
Exec[create_vm_anewvm]: Executing check ''/usr/bin/test -d /var/lib/kvm/
anewvm''
debug: Executing ''/usr/bin/test -d /var/lib/kvm/anewvm''

debug: Executing ''/usr/bin/vmbuilder kvm ubuntu -d CNDR -v -m 512 --
cpus=1 --rootsize=5096''
notice: //Node[10.0.0.165]/Virtual_machine[anewvm]/
Exec[create_vm_anewvm]/returns: executed successfully
debug: Finishing transaction 70279583715580 with 1 changes
But... the command is never executed. If I run /usr/bin/vmbuilder kvm
ubuntu -d CNDR -v -m 512 --cpus=1 --rootsize=5096 by hand I get:
root@venice:/etc/puppet# /usr/bin/vmbuilder kvm ubuntu -d CNDR -v -m

And the operation takes a while.
So I''m really stuck, it says it executes that command and that the
command is successful, but apparently, it doesnt execute the command,
or it is not successful (considering that I see no output, that the VM
is not created, that the command returns in less than a second
although it should take 3min+)...
I tried replacing the vmbuilder command by a simple "touch /tmp/
test" , that one works.
Any help would be much appreciated, I''ve been trying everything for
hours :(

The easiest to check is 3. Just remove the unless statement and try again. I''d try this first since it''s trivial. I think you can mostly test 1 by trying to run the command while redirecting the input from /dev/null You can indirectly do a partial job of testing 2 putting that command in a bash shell script and then executing the script explicitly using bash with the -l flag so bash will reconstruct some of the variables. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Hello Patrick, thank you very much for your help. I tested everything you said without much success. I ended up replacing my command by an "env" and reproducing the puppet''s shell environment variable in my shell to see if that could have an impact. It seems my puppet is running with an incorrect locale: LANG=C [...] LC_MESSAGES=C [...] LC_ALL=C root@venice:/tmp# /usr/bin/vmbuilder kvm ubuntu 2010-04-26 11:58:14,501 INFO : Cleaning up locale-gen does not recognize your locale ''C'' No idea why I wasnt able to catch those error messages before. I will continue to work on it and let you know if I manage to see where the locale is defined and why I wasnt seing that message (even after adding a 2>&1 > /tmp test at the end of the command line) Thanks -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

My guess is that the vmbuilder application has a foolish bug that uses LANG from the environment either by default, or by design, to help pre-populate the container. Try specifying the locale on the command line for vmbuilder, or overriding it in the puppet environment in the exec.

I don''t know what locale-gen does, so I don''t know if it is locale-gen that is broken or if vmbuilder is broken calling locale-gen when it shouldn''t. I have never used vmbuilder myself, but it does sound very, very weird that it wouldn''t be able to run when you use the C locale. That''s the most basic of all locales, and is actually entirely equivalent to not using locales at all.> No idea why I wasnt able to catch those error messages before.

Redirections are executed from left to right. Your redirection means "Clone the file descriptor for the current standard output [likely /dev/null] onto the file descriptor for standard error. Then open /tmp/test as the new standard output." After that, standard error will be open to /dev/null. Switching them around turns the meaning into "Open /tmp/test as standard output. Then clone the file descriptor for the current standard output [which is now /tmp/test] onto the file descriptor for standard error." /Bellman -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
