count.index for dictionary in Ansible

Is it possible to auto generate the vm10,vm11,vm12 in the below script (as count.index used in terraform) ? I would like to pass/define name "vm" and should be able to deploy 3 vm's with the different names vm10, vm11 and vm12. Please suggest a way, Thanks

- hosts: Target                         
  vars:
    machines:                  
      v10:
        mem: 1024
        vcpu: 1
      v11:
        mem: 1024
        vcpu: 1
  tasks:
  - name: img cpy
    copy:
      src: /root/pri.qcow2
      dest: /test/{{ item.key }}.qcow2
      remote_src: yes
    with_dict: "{{ machines }}"
  - name: Import/Load VM
    command: >
             virt-install --name {{ item.key }} --memory {{ item.value.mem }} --vcpus {{ item.value.vcpu }} --disk /test/{{ item.key }}.qcow2,bus=sata --import --os-variant generic --network default --noreboot
    with_dict: "{{ machines }}"

Use an inventory instead of a dict. You want 100 vms?

vms:
  hosts:
    vm[001:100]:
      mem: 1024
      vcpu: 1

This will be interpreted as vm001,vm002,...,vm099,vm100. Delegate the task to create them to localhost, since they don't exist when the task is run. Afterwards you can run the setup module and run tasks directly on the newly created VMs.

The corresponding playbook would look like this:

---
- hosts: vms
  gather_facts: no
  tasks:
  - name: copy qcow image to target path
    copy:
      src: /root/ovms/pri.qcow2
      dest: /root/ovms/test/{{ inventory_hostname }}.qcow2
      remote_src: yes
    delegate_to: target
  - name: Import/Load VM
    command: >
            virt-install --name {{ inventory_hostname }} --memory {{ mem }} --vcpus {{ vcpu }} --disk /root/ovms/test/{{ inventory_hostname }}.qcow2,bus=sata --import --os-variant generic --network default --noreboot
    delegate_to: target
