Hello,

Is there any way to fetch the size of all the virtual disks associated with a Domain??

I could not find one in the libvirt API., I tried using 'virStorageVol' and 'virStoragePool', but they returned null objects. Also I fetched 'virDomainBlockStats', but did not understand the information returned. i.e. 'rd_bytes' and 'wr_bytes'. Can we use this info for calculating the disk sizes?

In 0.8.1 we added a virDomainGetBlockInfo API that will give you this data directly.

Also, What does the size of the "img" file for a Domain represent? Is it the disc size?

virDomainGetBlockInfo gives both several sizes - see the header file comments for a description of what each means.
