Hi,
If you sign in chrome with a google account, chrome automatically activates/deactivates extensions (and other stuff you use) on all computer where you sign in chrome.
I find it useful to get the same extensions on my personal and professional laptops, in your case it seems like a bad thing. I believe it is a very nice feature with multiple computers but not with virtual machines, maybe there's an option to turn it off.
EDIT: I prefer to use only the web browser of the host which has chrome. VM are only used for specific softwares which does not run on Mac OS X.
