Moving VM’s to ProxMox

linux-category-inverted

In my previous post I installed ProxMox as my HyperVisor, but I didn’t mention anything about moving VM’s from Hyper-V over to it.  Well, here’s how I went about the process.

First, I tracked down this article, which has a pretty good detailed guide of the process.  Basically it comes down to the following:

  • Export the VM from Hyper-V to get a clean snapshot.
  • Transfer the .vmdk files up to the ProxMox host.
  • Create a new VM in ProxMox with the same CPU/Memory/Disks.
  • Convert the .vmdk files to the KVM format.
  • Start the VM and make any other changes, like IP, DNS, etc. that are required if the OS doesn’t detect the changed hardware properly.

There are a few caveats:

  • While exporting from Hyper-V, the completion percentage is displayed in the “Status” column of the Hyper-V manager.  However that column is not always visible depending on the resolution of the display and how large the window is, so make sure to expand the Hyper-V manager until you can see it.
  • In the article, the .vmdk is converted to a .qcow2 file, however for me the default format of disks is actually raw, so replace “-O qcow2” with “-O raw”.
  • Similarly, the location of the disks in the article is incorrect, it’s actually in /dev/pve, but that’s actually a link back to /dev/dm-? but you can use either.

That makes the conversion command something like:

qemu-img convert -O raw ~/BootDisk.vhd /dev/pve/vm-102-disk-1

Overall the migration process is quite easy, if a little slow between the transfer of the .vmdk files as well as converting them over to the new format.
