In 0.8.1 we added a virDomainGetBlockInfo API that will give you this data directly. I am currently using libvirt 0.6.3. Is there a way to do it in this version. If it is not at all possible in 0.6.3, and only possible from 0.8.1 onwards,

Thanks Daniel, then I will upgrade to 0.8.1. Because for the version upgrade, I will have to clearly explain to my client the reason why we need to upgrade. So, If I can fetch the same info as "virDomainGetBlockInfo" in 0.6.3 in some other way, that would be just awesome. Or if I can calculate the disk size from any other parameters, then please guide me on that also. Please help. Thanks and Regards Sagar Barve ----- Original Message ----- From: "Daniel P.

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.
