* **Para modificar vms KVM em execução podemos usar o virsh.**

* **Para o virsh se conectar ao "kvm" (libvirt) será necessário criar uma credencial no libvirt:**
```
# saslpasswd2 -a libvirt glichti
```

* **Para verificar as credenciais já existentes:**
```
# sasldblistusers2 -f /etc/libvirt/passwd.db
glichti@kvm-server: userPassword
```

# Usando o virsh:
* **Conectando ao KVM(Libvirt)**
```
# virsh
virsh # connect
Please enter your authentication name: glichti
Please enter your password:
```

* **Listando VMs**
```
virsh # list
 Id    Name                           State
----------------------------------------------------
 8     MQUEUE                         running
 10    NGINX                          running
```

* **Verificando a configuração atual do VNC de uma VM:**
```
virsh # qemu-monitor-command MQUEUE --hmp 'info vnc'
Server:
     address: 0.0.0.0:5902
        auth: vnc
Client: none
```

* **Desabilitando o vnc da VM**
```
virsh # qemu-monitor-command MQUEUE --hmp 'change vnc none'
virsh # qemu-monitor-command MQUEUE --hmp 'info vnc'
Server: disabled
```

* **Habilitando o VNC da VM sem senha:**
```
virsh # qemu-monitor-command MQUEUE --hmp 'change vnc :2'
virsh # qemu-monitor-command MQUEUE --hmp 'info vnc'
Server:
     address: 0.0.0.0:5902
        auth: none
Client: none
```

* **Listando clientes conectados ao vnc:**
```
virsh # qemu-monitor-command MQUEUE --hmp 'info vnc'
Server:
     address: 0.0.0.0:5902
        auth: none
Client:
     address: 127.0.0.1:45617
  x509_dname: none
    username: none
