launch vm in prox while it image is not on proxmox

[Ayush]

Hello Team ,

If I setup NFS and copy all vm to it, Can I directly lauch vm in Promox from NFS ?

 

[bbgeek17]

yes, of course. NFS is a valid storage type/pool for Proxmox.

However, the real answer is "it depends". For example, where do you copy the VMs from, what format they are in, how fast the NFS is, etc.

@bbgeek17 , what it the way to make it compatible . If we have PBS , can we sync NSF for vm dump with desired vm format which is readily available for Proxmox ?

I dont fully comprehend this statement, perhaps you can rephrase and expand this.

That said, PBS is a backup product. It stores the final backup in a special optimized archive format that allows for compression, deduplication and indexing. You cant just start a VM directly from an Archive.

But you have options to "live restore" a VM from PBS to PVE, so that VM starts while the backup is ongoing. The target storage in that restore operation can be NFS.

@bbgeek17 ,
I understand that I can't run vm directly form PBS as it store thing in compressed format. My question is that If I setup a NFS server in parallel with PBS .
As you mentioned that I can restore VM in pbs to NFS in uncompressed format. What is the way to do that and How can I use that un-compressed image in NFS to be available directly to Proxmox?

I can restore VM in pbs to NFS in uncompressed format. What is the way to do that and How can I use that un-compressed image in NFS to be available directly to Proxmox?

At a high level:
- Create NFS export on your NFS server, make it available to PVE (permissions, export restrictions, etc)
- Create NFS storage pool in your PVE (see link above, check PVE documentation, use point and click GUI)
- Browse to your PBS storage pool in PVE GUI , select the VM backup archive from available list
- Initiate Restore wizard and select your NFS storage pool as a target

Good luck

@bbgeek17 , Thanks for your help, I will try to create scenario and let you know in case I face any issue.

@bbgeek17, I test that scenario for 1 vm and it is working fine.
