Hi Alon, We created a qcow2 based-image for a VM whose size is bigger when it is created. When a VM is launched, it is a instance VM image which refers to the based-image. Initially, the image size of instance VM is smaller than that of the based-mage. But we found the image size of the instance VM kept growing, when a VM ran in idle state. The image size of instance VM is supposed to remain in a smaller size than the based-image. How come it keeps growing in size? Is it a normal issue? _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
