[vbox-dev] Plans

[Venefax]

Are there any plans to have support for more than 2GB or RAM ver windows VM?
And 64 Bits? That would be excellent before we can use this technology on a
datacenter.

Hi Klaus,

 

Thanks. It's great that you will put out the windows Shared Folders src
code.

 

As for the performance, I didn't do thorough testing, but you can get an
idea by doing this simple test:

 

share the whole host system drive, usually C:, then run notepad.exe

 

then launch map the shared drive in windows XP guest inside virtualbox, say,
you map Z: to be pointing to the host c: drive. then launch notepad.exe by
typing z:\windows\system32\notepad.exe

 

You will note that it's much slower compared to local notepad.

 

Thanks,

 

Huihong

To be honest I don't know. I'm not the one who wrote that code.
 
But I've asked them and learned that this issue is mostly solved. We 
need to update a few things (e.g. using the WDK 6001) then we can make 
the code part of VBox OSE. So I'm asking for a little patience since 
such cleanup work isn't really high priority. I'll let you know when 
we're ready.

See above. Hopefully done in about a week or so.

For contributions there's a wiki page describing the process: 
http://virtualbox.org/wiki/Contributor_information
 
Contributions are always welcome if they actually improve things. What 
tests did you run on your implementation? Getting a filesystem 
bullet-proof is hard work...
