Hello,

I would like to create a clone of a KVM machine - yesterday I was able to create a clone of the same machine within some minutes. Now it takes hours and is still stuck an "0%":

create full clone of drive ide0 (local:100/vm-100-disk-1.raw)

I wonder why this is the case. The task is running (i restarted it some minutes ago) - http://d.pr/tJn4

Any ideas what is going wrong again?

Edit: Disk I/O is low as the task is not writing any data to hdd (http://d.pr/1furj).


If I trace the process ID which is given in the overview, I'm getting this result:

select(24, [16 19], NULL, NULL, {0, 553078}) = 0 (Timeout)

select(24, [16 19], NULL, NULL, {1, 0}) = 0 (Timeout)

info version does not show anything because the VM is not running.
 
Update:

Now the VM is cloned (I do not know why) but it does not boot properly:
