Strange problem with vmdk kvm (migration) [solved]

Hi! I am trying to convert a vmdk to kvm.
1.) Step create a KVM VMDK VM. Initial empty KVM is bootable. OK.
2.) Copy the original vmdk file over the new vmdk file.
3.) ls -l shows: -rw-r--r-- 1 root root 5479727104 Nov 27 06:45 vm-112-disk-1.vmdk
4.) Now try to start the vm:
qm start 112 kvm: -drive file=/var/lib/vz/images/112/vm-112-disk-1.vmdk,if=scsi,index=0,boot=on: could not open disk image /var/lib/vz/images/112/vm-112-disk-1.vmdk: No such file or directory start failed: command '/usr/bin/kvm -monitor unix:/var/run/qemu-server/112.mon,server,nowait -vnc unix:/var/run/qemu-server/112.vnc,password -pidfile /var/run/qemu-server/ -daemonize -usbdevice tablet -name msc_vmdk.local -smp sockets=1,cores=1 -nodefaults -boot menu=on -vga cirrus -tdf -k de -drive file=/dev/cdrom1,if=ide,index=2,media=cdrom -drive file=/var/lib/vz/images/112/vm-112-disk-1.vmdk,if=scsi,index=0,boot=on -m 1024 -netdev type=tap,id=vlan0d0,ifname=tap112i0d0,script=/var/lib/qemu-server/bridge-vlan,vhost=on -device virtio-net-pci,romfile=,mac=52:41:1B:9E:9A:86,netdev=vlan0d0 -netdev type=tap,id=vlan1d0,ifname=tap112i1d0,script=/var/lib/qemu-server/bridge-vlan,vhost=on -device virtio-net-pci,romfile=,mac=76:6C:72:03:68:14,netdev=vlan1d0' failed with exit code 1

System says: could not open disk image /var/lib/vz/images/112/vm-112-disk-1.vmdk: No such file or directory
Strange - because ls -l /var/lib/vz/images/112/vm-112-disk-1.vmdk works 5.)

OK perhaps a VMDK format problem. Try a conversion.
Little tests before:
file vm-112-disk-1.vmdk vm-112-disk-1.vmdk:
VMware4 disk

image qemu-img info vm-112-disk-1.vmdk
image: vm-112-disk-1.vmdk
file format: vmdk virtual size: 100G (107374182400 bytes)
disk size: 5.1G backing f
ile: Ubuntu.vmdk (actual path: Ubuntu.vmdk)

Upps - same problem:
qemu-img convert -f vmdk vm-112-disk-1.vmdk -O qcow2 vm-112-disk-1.qcow2
qemu-img: Could not open 'vm-112-disk-1.vmdk': No such file or directory qemu-img: Could not open 'vm-112-disk-1.vmdk'
Similar problem
Any idea what is going wrong?

not really related to the issue but if you do a migration from vmware I suggest you use raw images on Proxmox VE. the migration can be done with clonezilla live-cd, see our migration page.

Problem fixed - problem was caused by a VMDK snapshoot. But the original error message was not really helpful.
