@olivierlambert Thanks a lot.
The Max vCPU was larger than the Physical CPU. Now it migrates successfully.

Thanks for your quick response.
My host has 4 vCPU and the VM is just 1 vCPU as shown in the screenshot.

Re: Trying to migrate

I tried to migrate VM from host1 to host2 it failed. the error message in log is:

@olivierlambert
Thank you very much for your assistance. Unfortunately, I have encountered another issue that I would like to address. I have forgotten the password for the XOA VM , but I do have the root password.

@Rashid @BenjiReis @olivierlambert
I appreciate your patience and guidance throughout the process. I am pleased to inform you that I have successfully completed the task at hand. However, I encountered two issues along the way. Firstly, one of my SMB Storage was corrupted and was not disconnecting properly. Secondly, the system was stuck in a restart loop. After resolving the SMB storage problem, I was able to restart the system and successfully add the new host to the existing pool.
Thanks all.

@BenjiReis @olivierlambert Thanks for your response. I have run the yum update & yum upgrade in both servers. no package is available.
And I think the problem is that both servers are Master, Am I correct?

@olivierlambert Thanks for your response. I have run the yum update & yum upgrade in both servers. no package is available.

I currently own two Dell Servers, one being the R710 with dual CPUs and 16 GB of RAM, and the other being the R20 with a single CPU and 32 GB of RAM. Recently, I installed XCP-ng 8.2.1 on both servers. After the installation was complete, each server became a master by default, resulting in two separate pools. However, I would like to have only one pool with one master and have my R720 server act as a slave in that pool. I have attempted various methods to resolve this issue, but unfortunately, none have been successful. It is worth mentioning that both of my XCP-ng installations are up to date. Please find the attached error log and screenshot for further reference.
Thank you in Advanced.
