High availability when both engine host and host with application vm failed
by Sergei Hanus 19 Oct '17

19 Oct '17

I want to make a setup, when workload is distributed between two sites are high availability mechanism protects from one site failure, restarting vms on another site. Scenario I use: 1. Poweroff hosted engine host, and then host with highly-available vm 2. Engine comes back on another site (which is fine). 3. What I expect, engine finds, that there's a host not available with HA vms, and restart these vms on another host. But, I only see in logs, that engine reports, that it cannot connect to that host (java.net.NoRouteToHostException: No route to host). Whel I poweroff just server with app vm, High Availability works correctly, performs fencing and restarts vm on another host. I use release 4.1 from RedHat. Has anyone faced similar issue? And, if yes, how could that be toubleshooted? Thank you in advance, Sergei.

Re: [ovirt-users] How to remove a MAC Pool from a cluster?
by Michael Burman 19 Oct '17

19 Oct '17

Hello James, The way to do it is to assign a new MAC pool range to this cluster and then to remove it. This can be done via - Administration > Configure > MAC addresses pool - There you can create/edit and remove MAC pool range entities. So create another desired MAC pool range, assign it to the cluster(via edit cluster) and remove the desired MAC pool range from the system.

Cannot uplaod ot ISO domain
by Alex K 18 Oct '17

18 Oct '17

Hi all, I have setup a self hosted setup with 3 servers with several volumes in replica 3. These gluster volumes are set on a separate network (on separate NICs on same servers), dedicated for gluster traffic. The engine does not have any NIC in this network. The ISO storage domain is also on top one of these gluster volumes. Hope this makes sense. When I try to upload an ISO file from engine, I get the following error: engine-iso-uploader -i ISO upload /usr/share/ovirt-guest-tools-iso/oVirt-toolsSetup_4.1-3.fc24.iso Please provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort): Uploading, please wait... ERROR: mount.nfs: No route to host Seems that the engine is trying to mount the volume and gives a no route to host. What is the correct procedure to add an ISO domain? Can't ISO domain be on a separate dedicated network which is reachable from each host? Thanx, Alex

Install oVirt in CentOS 7 Node
by FERNANDO FREDIANI 18 Oct '17

18 Oct '17

Hi. I have a host which I installed a Minimal CentOS 7 and turned into a oVirt Node therefore it didn't come with Cockpit installed and configured as it does in the oVirt-Node-NG. Comparing both types of Hosts I have the following packages below in each scenario. The only package missing between both is "cockpit-ovirt-dashboard". However I have already tried to install it and it was unable to show up the Virtual Machines correctly and control them. Is any specific or custom configuration needed in the cockpit config files to make it work properly ? - oVirt-Node-NG host: cockpit-ws-130-1.el7.centos.x86_64 cockpit-docker-130-1.el7.centos.x86_64 cockpit-ovirt-dashboard-0.10.7-0.0.6.el7.centos.noarch cockpit-system-130-1.el7.centos.noarch cockpit-networkmanager-130-1.el7.centos.noarch cockpit-storaged-130-1.el7.centos.noarch cockpit-130-1.el7.centos.x86_64 cockpit-bridge-130-1.el7.centos.x86_64 cockpit-dashboard-130-1.el7.centos.x86_64 - CentOS 7 Minimal install cockpit-system-141-3.el7.centos.noarch cockpit-ws-141-3.el7.centos.x86_64 cockpit-docker-141-3.el7.centos.x86_64 cockpit-dashboard-141-3.el7.centos.x86_64 cockpit-141-3.el7.centos.x86_64 cockpit-bridge-141-3.el7.centos.x86_64 cockpit-storaged-141-3.el7.centos.noarch cockpit-networkmanager-141-3.el7.centos.noarch Thanks Fernando

move disk and lv not removed
by Gianluca Cecchi 18 Oct '17

18 Oct '17

Hello, on an FC based environment I have a powered off VM Select VM --> disks subtab --> select one disk of 20Gb move at the end of the move apparently all went ok, but right after the "finished moving.." event I also get this error event VDSM host1 command HSMGetAllTasksStatusesVDS failed: Cannot remove Logical Volume: (['Cannot remove Logical Volume: (u\'c5d360f5-cd90-4b3e-bdef-924649bfbc5f\', "[\'2255c544-165b-4126-86ee-70e6d1edef9a\']")'],) After that I also do the same for another disk of the same VM with size 80Gb and it completes ok, without the same event error. So the problem doesn't occur always It seem to me that the old disk (aka old lv) has remained as a left over. And in fact the source storage domain doesn't show 20Gb of more free space... >From the SPM host # lvs | egrep "VG|2255c544-165b-4126-86ee-70e6d1edef9a" LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert 2255c544-165b-4126-86ee-70e6d1edef9a 072feb00-bc16-416d-9a23-39bde9cd3a94 -wi------- 20.00g 2255c544-165b-4126-86ee-70e6d1edef9a c5d360f5-cd90-4b3e-bdef-924649bfbc5f -wi-ao---- 20.00g # So it seems I have both the old LV on the original VG (2255c544-165b-4126-86ee-70e6d1edef9a) and the LV on the VG related to the target storage domain Is there any bug opened for this? How can I clean situation? Thanks, Gianluca

User cannot create VMs having sufficient permissions to do so
by nicolas＠devels.es 18 Oct '17

18 Oct '17

Hi, We're running ovirt-4.1.6.2-1. We have a user that logs into the user portal and tries to create a VM, but a message claiming that "There is no Cluster on which you can create a VM. Please check Data Center status and Cluster permissions." shows up. However, this user has permissions on the cluster (both VmCreator and DiskProfileUser, and also has a Quota created on the Cluster which allows him to create VMs). When clicking on the 'New VM' button, all we see in the engine.log is: 2017-10-18 10:59:31,825+01 ERROR [org.ovirt.engine.core.bll.GetAllLabelsQuery] (default task-103) [c23549c6-37a4-48d7-923d-6618e027cdca] Query execution failed due to insufficient permissions. This user has pretty much the same permissions as thousands of users who can create VMs, but this one can't. How can we debug what's happening and how to solve it? Thanks.
