The vmid.conf file stores configuration information for each virtual machine and is located at /etc/pve/nodes/<name>/qemu-server/<vmid.conf>. The directory structure divides all VM configuration files into categories based on nodes. For example, the configuration file for our VM #100 is stored in the following location:
# /etc/pve/nodes/pmx-01/qemu-server/100.conf
When we migrate a VM from one node to another, Proxmox just moves the configuration file to the destination node. If the VM is powered on during the migration, then the entire memory content of the VM is also migrated to the destination node. For our VM 100, if we migrate it to pmx-02, the second node in the cluster, then the location of ...
