Hello,
I'm experiencing a recurring problem when cloning virtual machines (VMs) on my Proxmox hypervisor, hosted by OVH. Specifically, when I clone a VM, it is assigned the same IP address as the source VM. Moreover, any IP address modification on the cloned VM is instantly reflected on the source VM, which is not the expected behavior. I can even access the shell of the cloned VM while it is powered off if the source VM is running.
I specify that the --full clone option has been used repeatedly, always with the same results.
CONFIGURATION:
Hypervisor: Proxmox 7.1-12 (Debian 11)
VM Operating System: Debian 10.13
Network Configuration: Static IP addresses on the vmbr0 bridge for the source VM and its clone
MAC Addresses: MAC addresses of both VMs are unique
UUID: UUIDs of source and cloned VMs are also distinct
Another particularly confusing symptom manifests in connectivity: once the cloned VM is started, it is impossible to connect to it unless the source VM is also running. If the source VM is stopped, connection to the cloned VM systematically fails.
I have verified the VM configuration files, and everything seems correct, particularly MAC addresses, UUIDs, and network interface configurations. This behavior also occurs in a local environment, which suggests the issue originates from the Proxmox configuration rather than OVH.
Can you help me identify the cause of this abnormal behavior and indicate if there are specific configurations that could explain this problem?
Thank you in advance for your help.
