Hi, I have just re-installed centOS 7 in 3 servers and have configured gluster volumes following this documentation: https://www.ovirt.org/blog/2016/03/up-and-running-with-ovirt-3-6/, But I have installed http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm package.

PXE LOCALBOOT issue
by Michael Deffenbaugh 11 Jul '18

11 Jul '18

Hey all, Provisioning a host with Foreman 1.17.1/Katello 3.6. The host kickstarts fine but when it goes to reboot, iPXE fails to load the local disk when the Foreman local boot kickstart menu ( https://github.com/theforeman/community-templates/blob/develop/provisioning…, line 4-10) sends the command "LOCALBOOT 0". It simply fails and says "No more network devices. No bootable device." Is this a bug in iPXE? Any input would be greatly appreciated! Regards, Mike

We do this with plain virt-install, nothing fancy. Searching the net for "unsupported configuration: CPU mode 'custom'" finds other relevant reports, you might want to check them. You can see the command in bootstrap_local_vm.yml . Please check/share versions of relevant packages (libvirt*, qemu*, etc) and relevant logs (libvirt). Also updating the subject line and adding Simone. Best regards, -- Didi

Unable to start VM
by Alex K 10 Jul '18

10 Jul '18

Hi all, I did a routine maintenance today (updating the hosts) to ovirt cluster (4.2) and I have one VM that was complaining about an invalid snapshot. After shutdown of VM the VM is not able to start again, giving the error: VM Gitlab is down with error. Exit message: Bad volume specification {'serial': 'b6af2856-a164-484a-afe5-9836bbdd14e8', 'index': 0, 'iface': 'virtio', 'apparentsize': '51838976', 'specParams': {}, 'cache': 'none', 'imageID': 'b6af2856-a164-484a-afe5-9836bbdd14e8', 'truesize': '52011008', 'type': 'disk', 'domainID': '142bbde6-ef9d-4a52-b9da-2de533c1f1bd', 'reqsize': '0', 'format': 'cow', 'poolID': '00000001-0001-0001-0001-000000000311', 'device': 'disk', 'path': '/rhev/data-center/00000001-0001-0001-0001-000000000311/142bbde6-ef9d-4a52-b9da-2de533c1f1bd/images/b6af2856-a164-484a-afe5-9836bbdd14e8/f3125f62-c909-472f-919c-844e0b8c156d', 'propagateErrors': 'off', 'name': 'vda', 'bootOrder': '1', 'volumeID': 'f3125f62-c909-472f-919c-844e0b8c156d', 'diskType': 'file', 'alias': 'ua-b6af2856-a164-484a-afe5-9836bbdd14e8', 'discard': False}. I see also the following error: VDSM command CopyImageVDS failed: Image is not a legal chain: (u'b6af2856-a164-484a-afe5-9836bbdd14e8',) Seems as a corrupt VM disk? The VM had 3 snapshots. I was able to delete one from GUI then am not able to delete the other two as the task fails. Generally I am not allowed to clone, export or do sth to the VM. Have you encountered sth similar. Any advice? Thanx, Alex

User permission. All user can access (start, shutdown) all vm in User/VM portal
by florentl 10 Jul '18

10 Jul '18

Hello, There is something I don't understand in permissions. I'm using Ovirt 4.2.3.5-1. I created a user : - ovirt-aaa-jdbc-tool user add etudiant2 --attribute=firstName=Etudiant2 --attribute=lastName=Etudiant2-Lastname - ovirt-aaa-jdbc-tool user password-reset etudiant2 --password-valid-to="2025-01-01 10:30:00Z" On the Administration Portal I gave him (etudiant2) the permission UserVmManager on only one VM and nothing else. But when he logs in the VM Portal he can view, start, stop all the VM. I think it's because all users are member of the group Everyone and this group has by default the UserRole. And in my config (the default/install config) the UserRole can do Basic Operation an VM. Moreover the UserRole is given to the group Everyone on all VM I created, and I can't remove this permission (Remove button is greyed). How can I make a VM "private", only visible by one user ? Thanks in advance, Florent

OVN ACLs
by Niyazi Elvan 10 Jul '18

10 Jul '18

Hi All, I have started testing oVirt 4.2 and focused on OVN recently. I was wondering whether there is a plan to manage L2->L7 ACLs through oVirt web ui. If not, how could it be possible to manage ACLs except command line tools ? Using opendaylight ?? All the best ! Niyazi -- Niyazi Elvan

Device Mapper Timeout when using Gluster Snapshots
by hsahmed＠gmail.com 09 Jul '18

09 Jul '18

I am facing this trouble since version 4.1 up to the latest 4.2.4, once we enable gluster snapshots and accumulate some snapshots (as few as 15 snapshots per server) we start having trouble booting the server. The server enters emergency shell upon boot after timing out waiting for snapshot devices. Waiting a few minutes and pressing Control-D then boots the server normally. In case of very large number of snapshots (600+) it can take days before the sever will boot. Attaching journal log, let me know if you need any other logs. Details of the setup: 3 node hyperconverged oVirt setup (64GB RAM, 8-Core E5 Xeon) oVirt 4.2.4 oVirt Node 4.2.4 10Gb Interface Thanks, Hesham S. Ahmed

hyperconverged cluster - how to change the mount path?
by Liebe, André-Sebastian 09 Jul '18

09 Jul '18

Hi list, I'm looking for an advice how to change the mount point of the hosted_storage due to a hostname change. When I set up our hyperconverged lab cluster (host1, host2, host3) I populated the mount path with host3:/hosted_storage which wasn't very clever as it brings in a single point of failure (i.e. when host3 is down). So I thought adding a round robin dns/hosts entry (i.e. gluster1) for host 1 to 3 and changing the mount path would be a better idea. But the mount path entry is locked in web gui and I couldn't find any hint how to change it manually (in database, shared and local configuration) in a consistent way without risking the cluster. So, is there a step by step guide how to achieve this without reinstalling (from backup)?
