[SOLVED] Migrating VMs from KVM to Proxmox.

[FaisalALi92]

Hello Everyone,

I am fairly new to Proxmox so bare with me

I have a ubuntu machine with KVM with a bunch of (VMs.qcow2) that I need to move to my new Proxmox server.

I need to move them to my proxmox server as I read in the docs the path to vms on pve is /var/lib/vz/images.

My PVE is configured with ZFS and I have two storages local and local-zfs.

So what is the proper way to accomplish that? I already searched but did not find anything.

Any help will be greatly appreciated.

Thank you

Hello,

if you transferred your VMs to the Proxmox server, you can create a VM and import the disk to the created VM using (qm importdisk).

Hi , Is there a specific path that I need to move my VMs on?

I am asking this because I previously performed the below steps for migrating:

1- Create a VM on Proxmox with the resources as my KVM image testvm.qcow2
2- after that I moved my testvm.qcow2 to the /var/lib/vz/images/101
3- I just renamed testvm.qcow2 to vm-101-disk-0.qcow2
4- I then went to ProxMox and started the VM

but since I configure My Proxmox with ZFS this time when I create a VM on Proxmox I do not find anything /var/lib/vz/images/ its is empty.

No.

but since I configure My Proxmox with ZFS this time when I create a VM on Proxmox I do not find anything /var/lib/vz/images/ its is empty.

you can do `zfs list`

root@stage-ve-01:/var/lib/vz/images# zfs list
NAME USED AVAIL REFER MOUNTPOINT
rpool 5.90G 862G 104K /rpool
rpool/ROOT 2.61G 862G 96K /rpool/ROOT
rpool/ROOT/pve-1 2.61G 862G 2.61G /
rpool/data 3.29G 862G 96K /rpool/data
rpool/data/vm-100-disk-0 3.29G 862G 3.29G -

Forgive me I am still a bit confused.

Now I need to create the VM on Proxmox with same resources as VM from KVM

move it to the following path rpool/data/vm-100-disk-0 then run import disk?

Hello,

move it to the following path rpool/data/vm-100-disk-0 then run import disk?

You can transfer the VM image disk to any path you want e.g /tmp/, then do `qm importdisk <VMID> <Your-VM-disk> local-zfs` command.

Hello,

I moved My disk and ran the command

Do I need to create VM with the same resources as the KVM machine then run the command using same VMID?

 

[FaisalALi92]

I have accomplished the VM migration by following the below.
Steps to migrate from KVM to Proxmox (ZFS)

1-copy the KVM disk .qcow2 to PVE server path /var/lib/vz/images
2- create a VM with same resources as the KVM Vm
3- run qm importdisk <VMID> <Your-VM-disk> local-zfs
4- attach newly created disk to the VM and delete the old one
5- change the boot option to the new disk then start the VM

Did it work? Sometimes in computing we see errors but the operation succeeds.
