Regarding wiki on Backup Storage
by shubham dubey 04 Jun '17

04 Jun '17

Hello, I just have put a PR for wiki on Backup Storage at ovirt-site[1]. The idea is to have a better backup solution for disaster recovery, in place of export storage domain. The idea is already discussed in mailing list earlier. Me and maor(as mentor) are working on this feature and till now I have done a push[2] for adding backup flag in database. I will appreciate everyone to review the wiki and share some feedback/comments about our implementation process.

Snapshot Image ID
by Marcelo Leandro 04 Jun '17

04 Jun '17

Good morning, I have a problem with snapshot, my last snapshot that should have the image base ID not contain this reference in sub-tab in the dashboard. how can see in the picture attached. I think that is necessary add this reference in the database again. The image exist in the storage and it is used for VM execution, but i think when I shutdown the VM it not start anymore. someone help me? Thanks, Marcelo Leandro

Storage domain does not exist
by Bryan Sockel 04 Jun '17

04 Jun '17

Hey, I am having an issue moving/copying vm's and templates around in my ovirt environment. I am getting the following error in my VDSM Logs: "2017-06-01 01:01:54,425-0500 ERROR (jsonrpc/5) [storage.Dispatcher] {'status': {'message': "Storage domain does not exist: (u'97258ca6-5acd-40c7-a812-b8cac02a9621',)", 'code': 358}} (dispatcher:77)" I believe this started when i destroyed a data domain instead of removing the domain correctly. I have since then rebuilt my ovirt environment, importing my gluster domains back into my new setup. I believe the issue is related to some stale metadata on my gluster storage servers somewhere but do not know how to remove it or where it exists. I found these two posts that seem to deal with the same problem i am seeing. https://access.redhat.com/solutions/180623 and https://access.redhat.com/solutions/2355061 Currently running 2 dedicated gluster servers and 2 Ovirt VM hosts servers, one is acting as an arbiter for my replica 3 gluster file system. All hosts are running CentOS Linux release 7.3.1611 (Core) Thanks

trying to test engine metrics, using ovirt-engine-metrics package
by Sergey Kulikov 03 Jun '17

03 Jun '17

Hi! I'm trying to deploy metrics in my ovirt test enviroment, configured fluentd on dst host, configured /etc/ovirt-engine-metrics/config.yml , after that trying to execute: /usr/share/ovirt-engine-metrics/setup/ansible/configure_ovirt_hosts_for_metrics.sh 4 host are configured correctly (This is Centos 7.3 Hypervisors) 1 host fails (this is the only ovirt-node host) Error: fatal: [<ovirt-node-host.fqdn>]: FAILED! => {"changed": false, "failed": true, "msg": "OSError: [Errno 0] Error\n"} After some digging into metrics ansible scripts I've found out, that it's setting port permissions in selinux: on ok host it looks like: # semanage port -l | grep collectd_port_t collectd_port_t udp 8125, 25826 on host with errors: # semanage port -l | grep collectd_port_t collectd_port_t udp 25826 I've tried to set it manually with no luck: # semanage port -a -t collectd_port_t -p udp 8125 libsemanage.semanage_module_info_set_name: Name 200 is invalid. OSError: Error maybe something is wrong in Ovirt-Node selinux, or it should be preconfigured in node image? Is there anything I can try to fix it? --

Nginx reverse proxy
by Petrica Pitineag 02 Jun '17

02 Jun '17

I have a physical server that hosts an all-in-one ovirt system. At the time there are only a handful of VMs but I plan to expand (both the number of VMs and the number of physical servers). As I use this for developing / testing various ideas (web apps) I sometimes need to have access directly to VMs from the internet (ports like 80, 443, sometimes others). What I would like is to install a reverse proxy (nginx) in DMZ and get rid of port forwarding system. My question is: is there any way (ovirt, plugin, 3rd party solution) that, when a VM is created, automatically creates the required entries in the reverse proxy so that a preselected +/- customizable list of ports are forwarded to the new VM? Example (where example.com is a preconfigured domain, site3 was the hostname the user entered, 192.168.0.3 is the IP allocated by the DHCP): server { listen 127.0.0.1:443 ssl; server_name site3.example.com; include common.conf; location / { proxy_pass http://192.168.0.3:80; } } And, as a followup: is there a way avoid manually creating an entry in the zone editor on registar's website? Thanks, PP

VM/Template copy issue
by Bryan Sockel 02 Jun '17

02 Jun '17

Hi, I am trying to rebuild my ovirt environment after having to juggle some hardware around. I am moving from hosted engine environment into a engine install on a dedicated server. I have two data centers in my setup and each DC has a non-routable vlan dedicated to storage. As i rebuild my setup i am trying to clean up my storage configuration. I am attempting to copy vm's and templates to a dedicated gluster setup. However each time i attempt to copy a template or move a vm, the operation fails. The failure always happens when it is finalizing the copy. The operation does not happen with all vm's, but seems to happen mostly with vm's created from with in Ovirt, and not imported from vmware. I have attached the logs from where i was trying to copy to templates to a new Gluster Filesystem Thanks Bryan

Export VM to ova or ovf format
by Brett Holcomb 02 Jun '17

02 Jun '17

Is there anyway to export a oVirt VM to an ova or ovf format. Right click export seems to be intended to transfer between oVirt storage domains. There is a project to setup a gui to do this but it's still in the planning stage. I've found various references that basically export it to an export domain and then you strip the disk or disks from it, create a VMware workstation VM, and then point it at the new disks you have. VMware's P2V converter is useless because it only converts Linux machines to an ESXi server which I don't have and once you do that it's another conversion to VMware Workstation. Guess nobody wants to run Linux on VMware workstation according to VMware. I'm trying to get some of my critical servers over to VMware Workstation on my Windows Physical box so when I upgrade oVirt I still have my basic network. I'm running a self-hosted Engine setup with only one Physical server at the moment. Thanks.

Problem while adding a VM NIC via REST API
by Bruno Rodriguez 02 Jun '17

02 Jun '17

Hello everyone, I have some scripts that create VMs, which are in perl using libcurl and oVirt REST API. They work quite fine but I'm experiencing something unusual. After I create the machine (let's suppose it's called server.pic.es) with UUID 123abc I post the following REST API call to https://... /vms/123abc/nics <nic> <name>server.pic.es_nic1</name> <interface>virtio</interface> <network><name>VLANXXX</name></network> </nic> The NIC is created and attached to the VM but it's network field is empty, not in the VLANXXX. I don't know if I'm missing something but this worked flawlessly with 3.6.9 REST API. Some people could say: "it's because you're using Perl". Yup, that's probably a mental issue of mine and I should visit a doctor about using it, but it doesn't work even using a fancy REST browser extension to send requests (ARC for chromium), anyways the REST reply is a "201: Created" that looks OK... Any idea or suggestion will be welcome.

Ovirt native Container support
by eric stam 02 Jun '17

02 Jun '17

Hi, I've been intrested if it is possible to run a native container in The current ovirt 4.0 version. In previous versions I found out that with some tricks it is possible. I do not know if it is stable or not. -- Gr. Eric Stam
