Hi, I am trying to use a base image.qcow2 file and create many VMs out of it using following command.
qemu-img -f qcow2 -b image.qcow2 vm1.qcow2 Now image.qcow2 is a 40G disk with 23G worth of data. So its virtual size is 40G and actual size is 23G. However, for vm1.qcow2 I am seeing that its virtual size is 23G. When I boot using vm1.qcow2, kernel panics saying that it can't read super block at some big offset, which I feel is due to this virtual size problem as ext3 might be trying to read super block of each block group. Seems like a bug right? Thanks, Nitin
