Migrate a KVM image to proxmox ceph

[jonathan2493]

hi,

I have a kvm image with the format of qcow2, I want to place it in my proxmox cluster. I am using ceph as the storage for created VMs.
How do take the KVM image and place in ceph, and re run it inside proxmox?
thanks!

Hi,
copy the qcow2-file to local storage and use storage mirgration to move the vm-disk to ceph-storage.

How do I do that?

Lets say Ive placed the qcow image in /var/lib/vz/images/.

I have a ceph pool named ceph. I want the qcow2 file to be placed in the ceph pool.
Any specific commands on how to do that?

thanks !!

Hi,
qcow2 is usable on an filesystem only (like local storage, nfs) - on ceph the images are stored as rbd-"file" (rados block device).

create an VM with an qcow2-hdd on local storage (like vm 111) and move your qcow2-file to this hdd-file (old content will be overwritten!!!):

mv your_qcow2_file.qcow2 /var/lib/vz/images/111/vm-111-disk-1.qcow2

In the pve-gui use "Move Disk" -> Target storage ceph + delete source.

That's all.
