Failing to migrate from vSphere to Proxmox

So I've spent countless hours now trying to migrate my vSphere VM's to Proxmox, but haven't been successful.

My vSphere VM directory has the following files :
  • VMNAME.nvram (9KB)
  • VMNAME.vmdk (1KB)
  • VMNAME.vmsd (0KB)
  • VMNAME.vmx (3KB)
  • VMNAME.vmxf (1KB)
  • VMNAME.727c2cda.hlog (2KB)
  • VMNAME-aux.xml (1KB)
  • VMNAME-ctk.vmdk (321KB)
  • VMNAME-flat.vmdk (5242880KB)
  • vmware.log
  • vmware-[11-16].log
What I've tried so far :
  1. Copy all of those files to a Windows Server VM.
  2. Install VMWare Workstation on this VM.
  3. Run "C:\Program Files (x86)\VMware\VMware Workstation\vmware-vdiskmanager.exe" -r VMNAME.vmdk -t 0 VMNAME-pve.vmdk
  4. This returns two new files which are VMNAME-pve.ctk.vmdk (321KB) and VMNAME-pve.vmdk (2723776KB).
  5. Create a new Proxmox vm with ID 225, with no media under the OS tab and Type: Linux, a 6GB SCSI Hard Disk, 2GB of Memory and a network interface(virtio).
  6. Copy the files returned by vdiskmanager from the windows server vm to /var/lib/vz/images/225 on my proxmox host.
  7. Run qemu-img convert -f vmdk VMNAME-pve.vmdk -O qcow2 VMNAME-pve.qcow2, which successfully creates a 2.6G qcow2 file.
  8. Delete the .vmdk files on the Proxmox host.
  9. Run qm rescan.
  10. Booting the VM now returns: Boot failed: Not a bootable disk.
I've also tried using vdiskmanager to convert to preallocated virtual disk and I've tried using the Rescue CD Disk method, both result in the same error when booting. I consider myself fairly knowledgeable with vSphere and I've been using it for years now to run dozens of VM's, but I've decided to move my cluster to Proxmox for the sake of open source and trying/learning something new. I'm kind of at a loss here though and would greatly appreciate any help.
 
Hi,
try to copy

to /var/lib/vz/images/225/vm-225-disk-1.vmdk

then run qm recan.

If this work use move disk to convert the disk from vmdk to qcow2

Hi,
what is the output of
Code: 
file /var/lib/vz/images/225/vm-225-disk-1.vmdk
???

Your disk was 5GB in size, is this correct?


Can you post the VM-config?
Code: 
qm config 225
What type of OS is inside the guest? Windows or linux?

Thanks for your reply. The VM id is now 333.
Output of file /var/lib/vz/images/333/vm-333-disk-1.vmdk is
Code: 
vm-333-disk-1.vmdk: DOS/MBR boot sector

The disk size was 5GB in vSphere, but I set it to 6GB in proxmox, just for good measure.

WM-config:
Code: 
bootdisk: scsi0
cores: 1
ide2: none,media=cdrom
memory: 512
name: KMS
net0: virtio=16:12:D4:D1:57:4E,bridge=vmbr1,tag=50
numa: 0
ostype: l26
scsi0: BANK_SSD:vm-333-disk-0,size=6G
scsihw: virtio-scsi-pci
smbios1: uuid=254af9ca-f7dc-430e-956d-3bb0bd1d9bcc
sockets: 1
vmgenid: 5030c7c2-efcb-43b0-b5b8-490f507d8bb4
Should I change scsi0 to BANK_SSD:vm-333-disk-1,size=5G maybe ?

The guest os is Debain Linux.

Ok,
that's looks good.
WM-config:
Code: 
scsi0: BANK_SSD:vm-333-disk-0,size=6G

here is the mistake!
BANK_SSD:vm-333-disk-0 is not /var/lib/vz/images/333/vm-333-disk-1.vmdk

Pleas post your storage-config
Code: 
cat /etc/pve/storage.cfg

No, that's not the issue

That should work fine.

My storage config is

Code:

   path /var/lib/vz
   content vztmpl,iso,backup

lvmthin: local-lvm
   thinpool data
   vgname pve
   content images,rootdir

   export /Elliot/ISO

   server *hostname*
   content iso

Ok,
you can do two things - rename the config (and modify your storage config to allow images on storage local - but should work without this):
1.
Code: 
scsi0: local:333/vm-333-disk-1.vmdk,size=5G
or, preferred - copy the data
Code: 
dd if=/var/lib/vz/images/333/vm-333-disk-1.vmdk of=/dev/BANK_SSD/vm-333-disk-0 bs=1M
after that, start the VM and enjoy.

ok,
device not active - activate with
Code: 
lvchange -a y /dev/BANK_SSD/vm-333-disk-0
and use dd again.

Hi,
just see, that you filled your root-partition (No space left on device) because you wrote to an new file (the logical volume wasn't open).

To correct stop the VM 333, deactivate the LV and remove the big file:
Code: 
qm stop 333
lvchange -a n /dev/BANK_SSD/vm-333-disk-0
ls -lsa /dev/BANK_SSD/vm-333-disk-0

# if this is not an link to an dm-file and has an size near 4GB, then remove
rm /dev/BANK_SSD/vm-333-disk-0

# and again
lvchange -a y /dev/BANK_SSD/vm-333-disk-0
ls -lsa /dev/BANK_SSD/vm-333-disk-0

dd ...

Thanks! I'm slightly confused and not exactly sure what I did, but It's working now.
