[one-users] Mapping OpenNebula VM status to Libvirt like ones

[Carlos Martín Sánchez]

Hi,

OpenNebula 1.4 had a libvirt interface, and the VM states haven't really
changed. This is the relevant code, taken from [1]:

  341         switch(one_state) {
 342         case 3:                                     /** running */
 343             if (vm->state!=VIR_DOMAIN_SHUTDOWN)
 344                 vm->state=VIR_DOMAIN_RUNNING;
 345             break;
 346         case 5:                                     /** pause */
 347             vm->state=VIR_DOMAIN_PAUSED;
 348             break;
 349         case 6:                                     /** done */
 350             vm->state=VIR_DOMAIN_SHUTOFF;
 351             vm->def->id=-1;
 352             break;
 353         case 7:                                     /** error */
 354             vm->state=VIR_DOMAIN_CRASHED;
 355             break;

Regards.
