[Spice-devel] Image size of the instance VM (qcow2 format)

[Charles.Tsai-蔡清海-研究發展部]

Hi Alon,

Do you have any idea about this issue? We doubt this issue is caused by the Windows swap file(virtual memory) that Windows OS pages the memory contents to it during the run-time. However, we did disable the swap file setting from Windows. The image size of the instance VM still keeps growing. Can you tell us what area we need to study so as to attack this issue if you know it? Thanks.

Subject: Image size of the instance VM (qcow2 format)

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?
