Oh great, I was thinking of something like that. It could really help and avoid call to storage.

Btw, I have some plans regarding to size_info in QemuServer. 

To avoid accessing storage to often, we can add a 'size=XX' tag to the configuration. 

For example: 

ide0: /dev/sdb,size=5 

This is just a hint, we add that when we add/modify a drive. 

Additionally, we implement a 'qm rescan' command, which search for unused drives and also 
updates the file sizes. 

What do you think?
