[coLinux-users] q: dynamic sized image & memory sharing.

[Chan K. H. <cha...@gm...>]

Hi,

2 questions:

1) dynamic sized images.
Can images be dynamically sized?
ie: a file having the root file system only actually occupy 1GB hdd 
space temporarily (but is supposed to be an 80GB hdd).
I've also learnt that linux is capable of mounting a filesystem that is 
backed by a file.
ie: use dd to create a file called /tmp/myfs, having size of say 10GB; 
/tmp/myfs can then be mounted & formatted to ext2fs.
Is there a way to make this dynamically sized?
I'm looking for something similar to what's in VMWare (option to only 
consume required disk space later).

2) memory sharing.
My laptop has 4GB memory.
Can both Windows & coLinux just assume it both has 4GB memory?
Say if an application under Windows takes up 3GB memory, then only 1GB 
will be available for coLinux.
Can this be done?
Am wondering if this option is available instead of making coLinux take 
up a fixed memory of say 2GB, making memory unavailable to my other 
Windows apps. This also makes memory from Windows unavailable to coLinux 
when my coLinux needs more than 2GB.

Thanks & best regards,
