Dear All, I have three servers with VDSM and a vm with ovirt 4.2.4.5-1.el7, all using a Centos 7. I still need you for a problem with a virtual machine. I needed to connect the tape of a hypervisor to a vm and then I changed the Host Device by adding the ST driver. After making this change the VM is no longer playing even after removing this hook. Does anyone have any ideas? Thanks a lot Best Regasrds Enrico -- _______________________________________________________________________ Enrico Becchetti Servizio di Calcolo e Reti Istituto Nazionale di Fisica Nucleare - Sezione di Perugia Via Pascoli,c/o Dipartimento di Fisica 06123 Perugia (ITALY) Phone:+39 075 5852777 Mail: Enrico.Becchetti<at>pg.infn.it ______________________________________________________________________
