bootdisk: ide0 
cores: 1 
ide0: nexentatestapi:vm-277-disk-1,size=32G 
ide2: none,media=cdrom 
memory: 512 
name: test 
net0: e1000=8A:23:4D:FB:B0:3A,bridge=vmbr0 
ostype: l26 
sockets: 1 



with gui only:

create full clone of drive ide0 (nexentatestapi:vm-277-disk-1) 
TASK ERROR: clone failed: unable to create image: Insecure dependency in exec while running with -T switch at /usr/share/perl/5.14/IPC/Open3.pm line 187. 


qm clone command line works fine

I am unable to reproduce it: 

# qm config 105 
bootdisk: virtio0 
cores: 1 
ide2: none,media=cdrom 
memory: 512 
name: nextest 
net0: virtio=AE:DE:EF:50:62:58,bridge=vmbr0 
ostype: l26 
sockets: 1 
virtio0: nex1:vm-105-disk-1,size=1G 

I can make a full clone without problems. 

Please can you post your VM config?
