nova driver fails to connect to VCenter when VCenter password has "$$" in it

[chetanpatige]

I have VCenter with username="Testuser" and password as "Pa$$word". I see that the nova.conf had the password right i.e., "Pa$$word" but the nova driver failed to connect to the VCenter. I was able to login to the VCenter via VSphere Client. On investigation i see that the nova driver took the password as "Pa$word" and not "Pa$$word".

This is working as expected. The config files support string interpolation to combine option values using $varname as the syntax. Two $ are used to disable interpolation, so $$ becomes $ in the config value. In your case, where you need $$ as the output, the input should include $$$$.

I did a quick scan and didn't find this information in the configuration reference (http://docs.openstack.org/icehouse/config-reference/content/). Maybe we can add a short "syntax" section?

Doug, do you have some more information on this syntactic sugar, please? Any reference?
