Currently, we are studying how to use the pythob-libvirt API to operate VMS. After several twists and turns, the migration function is completed: The Code is as follows: Import libvirt # virsh migrate -- live KK qemu + TCP: // 192.168.4.87/system TCP: // 192.168.4.87 # conn = libvirt. open ('qemu: // system') # dest_conn = l
