Does anyone has such experience that you accidentally delete the used disk image when virtual machine is running?
I would expect that the virtual machine will fail immediate, but, surprisingly, it still running perfectly. I have tried to execute many I/O commands and even create very large files by "dd" which are totally more larger then the vm's memory size. But it is still live.
Can anyone explain why?
Server info: ubuntu 12.04 with KVM and libvirt installed from default repo. VM's disk image is qcow2 format.
