Question

Restore worksation on Proxmox

M
Userlevel 1

Hello together,

 

I have the following Problem.

I want to migrate a Workstation to am VM in Proxmox.

I found the following Thread with nearly the same question

Now my Problem:

When I start the VM it boots into the Veeam restore option but the Agent shows the Error “Failed to resolve ClientID. Machine doesn´t have identifiers”.
Like in the Thread above I switched the VM-Bios from SeaBios to Uefi but then the VM doesn´t boot into Veeam.

Is there a possibility to solve the Error

 

Thank you for your help.

 

Markus

ProxMox is not supported by Veeam at the moment.

The support is announced though:

As Joe stated @MRieger , Proxmox was announced to be supported, but according to the official announcement on their blog site, it will not be GA until around Quarter 3 of this year (Fall sometime). You can read their official announcement below:

Although, it doesn’t seem you’re working with Veeam & Proxmox directly, but using the Veeam Agent (so, an indirect approach)? Even so, there could be something about using a Proxmox-based VM which the Veeam agent is not able to read & thus the error. If no one else can post a solution, you may try and post something on the Veeam Forum.

I've seen this error a few times so far but no specific solution. On Reddit someone replied that changing from VM version 8 to 8.1 solved the issue, while someone else used pc-i440fx-8.0 instead. Maybe this is helpful to you, or if you find a different solution then please share it here.

Hi @MRieger - I just wanted to follow up to see if you were able to move the VM to Proxmox and get it working or not?  If you can post the answer here then mark best answer from above that helped you the most or your answer if none of them are relevant it would be helpful for other community members.  If there was no answer let us know and we can convert this to discussion instead of question.

Hi,
I cannot answer for MRieger, but we had similar issues when we migrated 18 host with a lot of VMs from VMware to Proxmox.

Every time we had a VM which was original as BIOS - in Proxmox “SeaBIOS” - we need to change the “Machine” to 8.0. Else we would get the same “Failed to resolve ClientID. Machine doesn´t have identifiers” error and the VM would not boot.

Hardware → Machine

When using UEFI we can use Machine 8.1 and 8.0 with no issues.

Hope others can use this information, if they find this thread.

Thanks for sharing this and hopefully it helps the OP resolve the issue.
