Hi Team,
I am using libvirt module to retrieve configuration of the virtual
machines, Can you please tell me how to retrieve the disk space of the
Virtual machines. In my KVM hyper i am running two virtual machines.

virDomainGetBlockInfo tells you how much host resources the guest disk
is using, but to find out from the guest itself how much the guest
thinks it has free, you'd have to add a new guest agent command.

You can get the block devices assigned to a VM with the following..
virsh domblklist <machine>
Target Source
------------------------------------------------
vda /VirtualMachines/KVM/machine.qcow2
hdc /VirtualMachines/iso/gparted-live-0.12.1-1.iso
For more detailed info, you can use qemu-img on the above returned block device
qemu-img info /VirtualMachines/KVM/machine.qcow2
image: /VirtualMachines/KVM/machine.qcow2
file format: qcow2
virtual size: 250G (268435456000 bytes)
disk size: 174G
cluster_size: 65536

Hi Adam,
Thanks for the reply.
qemu-img info /VirtualMachines/KVM/machine.qcow2****

Thanks for the reply.

Ideally, libvirt should expose everything you need so that you don't
have to resort to raw qemu-img calls (we aren't quite there yet, but
that's another story).
How can i do this from remote host using libvirt module ? Started using and

In this particular case, use virDomainGetBlockInfo (aka 'virsh -c
qemu://remote/system domblkinfo $dom $disk').
