Hey all,

while strictly following the guidelines [1] on how to spawn an instance on
the same host as another instance,
I run into the error, that it cannot find some instanced called: "[", which
- of course - is not the UUID I specified.
I tried dropping the [ ] and just passed the UUID right away, but still,
then is just takes the first character of
the UUID and says, that it can't find this one.

my exact command line looked like this:

nova boot --image 6c73d25e-df93-4c96-a803-9d419a367267 --flavor 16 --hint
same_host=[df5fd16b-271d-45ac-9e9a-5d3ad33920e5] $instance_name

And that's the error in the log then.

Any ideas if it's my fault or how to work around this?

Many thanks in advance,
Christian Parpart.
