qcow2 image growing without reason ?

qcow2 image growing without reason ?

[Ben Budts]

Hi,

I've been running kvm21 for a long time (just upgraded to kvm-33 with 2.6.22.1)

I have a 60GB qcow2 image, I noticed the image was growing without me installing software on the guest os...(WIN XP)

When I select all my files and take properties (in win xp that is), it says 3.7GB, as expected...

The image is allmost the double though (6.4GB) when i look at the qcow2 image, 
when taking the properties of the HD in win xp it also indictates 6.4GB.

I've been installing some software, after each install I did a restart, bakupped the image etc...

Any idea's ?

If Windows says the disk size is 6.4GB, then the qcow image certainly 
can't be smaller.

Maybe you have a large paging file, or perhaps you need to run chkdsk.

Hum, then the used disk space is 6.4GB. "Selecting all files" may skip
hidden/system/whatever files according to explorer settings.
