Hi, I have instantiated a “non persistent” vm. System has copied image to system datastore as it is expected, later it has started it successufly, nevertheless, after the first poweroff I get the following error when I try to start it “virsh resume 22”: > Sat Feb 18 23:04:18 2017 [Z0][VM][I]: New LCM state is BOOT\_POWEROFF > Sat Feb 18 23:04:18 2017 [Z0][VMM][I]: Generating deployment file: /var/lib/one/vms/22/deployment.8 > Sat Feb 18 23:04:18 2017 [Z0][VMM][I]: Successfully execute transfer manager driver operation: tm\_context. > Sat Feb 18 23:04:18 2017 [Z0][VMM][I]: ExitCode: 0 > Sat Feb 18 23:04:18 2017 [Z0][VMM][I]: Successfully execute network driver operation: pre. > Sat Feb 18 23:04:19 2017 [Z0][VMM][I]: Command execution fail: cat \<\< EOT | /var/tmp/one/vmm/kvm/deploy ‘/var/lib/one//datastores/0/22/deployment.8’ ‘vdicnode01-priv’ 22 vdicnode01-priv > Sat Feb 18 23:04:19 2017 [Z0][VMM][I]: error: Failed to create domain from /var/lib/one//datastores/0/22/deployment.8 > Sat Feb 18 23:04:19 2017 [Z0][VMM][I]: error: operation failed: domain ‘one-22’ already exists with uuid 06892f7c-40c1-4f8a-8c87-431518150a04 > Sat Feb 18 23:04:19 2017 [Z0][VMM][E]: Could not create domain from /var/lib/one//datastores/0/22/deployment.8 > Sat Feb 18 23:04:19 2017 [Z0][VMM][I]: ExitCode: 255 > Sat Feb 18 23:04:19 2017 [Z0][VMM][I]: Failed to execute virtualization driver operation: deploy. > Sat Feb 18 23:04:19 2017 [Z0][VMM][E]: Error deploying virtual machine: Could not create domain from /var/lib/one//datastores/0/22/deployment.8 I can start the virtual machine without problems from “virsth start one-22”.

Hi Oscar, are you using multiple hosts? If yes, check the /etc/libvirt/libvirtd.conf in the `host_uuid =` part. If they are the same on the Hosts, the problem could be located there. I was facing this issue in the past and solved it with the following sed in my installation routine. Suitable for Debian 8.7.1 you will need the `uuid-runtime` `sed -i 's|#host_uuid = "00000000-0000-0000-0000-000000000000"|host_uuid = \"'$(uuidgen)'\"|g' /etc/libvirt/libvirtd.conf` Pecadis ---

Hi Pecadis, I have forced the host\_uuid but I get exactly the same error. Thanks a lot. ---

Hi Oscar, another thought. Are you using a shared storage? Could you print the `onedatastore list` please? Pecadis ---

Yes, I’m using a shared datastore for images (nfs v3) > [root@vdicone01 ~]# onedatastore list > ID NAME SIZE AVAIL CLUSTERS IMAGES TYPE DS TM STAT > 0 system - - 0,100 0 sys - ssh on > 1 default 6.7G 82% 0 0 img fs ssh on > 2 files 6.7G 82% 0 0 fil fs ssh on > 100 nfs-vdic-imag 80G 78% 0,100 1 img fs shared on Afterwards, I have to nodes: > [root@vdicone01 ~]# onehost list > ID NAME CLUSTER RVM ALLOCATED\_CPU ALLOCATED\_MEM STAT > 0 vdicnode01-priv vdicube 1 100 / 400 (25%) 1024M / 3.7G (27%) on > 1 vdicnode02-priv vdicube 0 0 / 200 (0%) 0K / 3.7G (0%) on Un saludo, ---

Hi oscar, I think you hit the same issue as i had ( [SOLVED Live Migration "failed: error: Cannot access storage file" on 5.2.1](https://forum.opennebula.io/t/solved-live-migration-failed-error-cannot-access-storage-file-on-5-2-1/3762/4) ) In short terms: Change your “system” Datastores to shared as well.

Hi, I have read the post you ha attached and I think I’m not experiencing the same issue. In my scenario, system datastores are local and I don’t want to perform any live migration. I just want to start it from opennebula as I can executing virsh start xxx. Thanks a lot ---

Hi, In my case, for any extrange reason, the problem was that a “normal” kvm xml has been deployed. In my case: `/etc/libvirt/qemu/one-22.xml` As it was registered by libvirtd, it was not possible to register a new one-22 VM. Thanks a lot,
