[SOLVED] import a virtualbox vm on a system with zfs storage

[Dieter Toews]

Hi all,

I'm trying to follow these guides:

http://www.binaryheartbeat.net/2016/05/importing-ova-container-into-proxmox.html
http://cheznick.net/main/content/converting-a-virtual-machine-from-virtualbox-to-kvm
http://pve.proxmox.com/wiki/Migration_of_servers_to_Proxmox_VE#Converting_to_qcow2

To convert the virtualbox virtual machine the above links say to to

1. extract the files within the ova format file
   
2. convert the resulting disk image using qemu tools
3. setup a virtual machine in proxmox with settings that mirror those you where using for virtualbox
4. overwrite the newly created virtual machine disk image with the transformed disk image that you created in step 2

i know that storage of vm images is setup a little different when using zfs . when i do

 zfs list

i see zfs data sets for the three vms i've setup so far:

root@proxmox1:/# zfs list
NAME                       USED  AVAIL  REFER  MOUNTPOINT
rpool                     35.7G  1.02T    96K  /rpool
rpool/ROOT                20.1G  1.02T    96K  /rpool/ROOT
rpool/ROOT/pve-1          20.1G  1.02T  20.1G  /
rpool/data                7.11G  1.02T    96K  /rpool/data
rpool/data/vm-100-disk-1  1.46G  1.02T  1.24G  -
rpool/data/vm-101-disk-1  5.65G  1.02T  5.65G  -
rpool/data/vm-102-disk-1    64K  1.02T    64K  -
rpool/swap                8.50G  1.03T    64K  -

i notice that the data sets don't have mount points listed. Are they secretly mounted somewhere else? how do the VMs see there disk images if the data sets aren't mounted in proxmox? is is safe to just mount the dataset for the vm i want to mess with (in my case vm-102)?

Create your destination VM on ZFS with the exact size of your disk and then you can convert your disk to a zvol directly:

$ qemu-img convert -O raw <infile.(vdi|vmdk|$whatever)> /dev/zvol/rpool/data/vm-<id>-disk-1

worked like a charm - thanks LnxBil

Bill, I followed the steps but I get an error, see attached

You should boot a live Linux and investigate why the labels have changed. Normally, this should not be the case if the whole virtual disk was correctly converted.

"Create your destination VM on ZFS with the exact size" how do I get the exact size of my .img file?
