RHEL 7 VM MIGRATION FROM IBM POWER TO PVE 8.3

[lordem67]

Hi everyone, i am new on proxmox.
Please i need to transfer a rhel 7 VM from my IBM Power server to a proxmox node but after transfering the disk and booting the VM in proxmox it boots on initramfs.
This is how i proceeded :
1- Transfer the disk from IBM to proxmox node using rsync
2- Create a VM on proxmox in seabios and i440fx
3- Import the VM disk to the new machine in proxmox
4-Boot

Thanks in advance!

I didn’t understand the situation.

Are you saying that you tried to perform steps 1–4 in order to P2V a RHEL system that was running on an IBM Power server to a VM on Proxmox VE, but the initramfs driver cannot be loaded?

If that is the case, I think the process would be as follows:

1. Change the disk to IDE
2. Boot the system
3. Rebuild initramfs so that it loads the virtIO driver
4. Change the disk to SCSI
5. Boot the system

I am facing an issue trying to migrate a RHEL 7 VM from an IBM Power server (Power architecture) to a Proxmox VE cluster (x86_64) to use it as a backup server.

I transferred the VM, but when booting it on the Proxmox node, the boot fails and the initramfs does not load.

Given the architecture difference between IBM Power (ppc64le) and Proxmox (x86_64), what is the best approach to make this VM bootable? Do I need to use QEMU cross-architecture emulation in the VM configuration, or is it mandatory to reinstall a fresh RHEL 7 x86_64 VM on Proxmox and manually migrate the backup data/configurations?

Thanks for your help!

I don't think there is one for this conversion.

reinstall a fresh RHEL 7 x86_64 VM on Proxmox and manually migrate the backup data/configurations?

I believe this is your only path.

Ok thanks

I see, so the architecture is different.
In that case, I think what bbgeek17 said is correct.
Also, this was my first time learning about the terms IBM Power and ppc64le architecture, so it was very informative for me.
