If the VMs get successfully created, but the OS kernel panics or similar, then likely you need to set the CPU model for them to a newer one. You can apply it at VM or template level in the Settings of them, or enable a particular CPU model in the agent.properties file.

Subject: Re: Unable to create VM with Latest OS

Hi,

What's the error ? failed to deploy vms, or vms are stuck at booting ?

These OS distros have minimum requirement on CPU.

Kind regards,

Wei
