Raw image selected but qcow2 created

[sabueso]

Hi

I was trying to create a virtual machine with a raw disk image in Proxmox 4.4, so I tried to do that, selecting the option in the creation menu. Once created, i notice that resulting image is a qcow2, despite not having chosen this format.

If i look the config file, i found this:

root@home:/# cat /etc/pve/qemu-server/102.conf
bootdisk: scsi0
cores: 1
ide2: iso:iso/debian-8.7.1-amd64-netinst.iso,media=cdrom
memory: 512
name: debian-test
net0: virtio=5E:1D:CD:AF:EC:71,bridge=vmbr0
numa: 0
ostype: l26
scsi0: local:102/vm-102-disk-1.qcow2,size=10G
scsihw: virtio-scsi-pci
smbios1: uuid=0dde7d8e-787f-41c6-9388-1e9e18ff7b1d
sockets: 1

If i try to run the image, i get the following error:

Virtual Environment 4.4-13/7ea56165
Virtual Machine 102 ('debian-test' ) on node 'home'

¿Is there any know issue about this behaviuor?
Thanks!

If you run on ZFS, you need to use the ZFS storage type (not the directory storage type).

Ok, roger that. I'm running ZFS and, alternatively, i created a directory to store virtual machines with no zfs-storage-format.

Thanks!

UPDATE: If i create new storage directory (as shown in picture) now i can create raw images correctly, so seems to be something related to the default "local" storage.
