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

Host fencing issues
by Fernando Fuentes 18 Oct '17

18 Oct '17

Hello Team, I updated one of my host on my cluster and after it finish and try to activate the host it quickly claimed that the host was unresponsive and it fenced the host... Now every time I try to activate the host it clames that is unresponsive and proceeds to fence it... This was not happening before the update.... The host is reachable with no problems nor issues... Any ideas? Centos 7.4 x86_64 host. Attached is the vdsm log engine is oVirt Engine Version: 4.0.2.6-1.el7.centos Regards, -- Fernando Fuentes ffuentes(a)txweather.org http://www.txweather.org

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.

Hi, I was trying to setup separate gluster network in ovirt. But I saw hosted-storage volume which I had created for hosted-engine still running on managment network. Can I move that hosted-storage gluster volume on gluster network ? Thanks, ~Rohit

Unresponsive instance
by JC Clark 17 Oct '17

17 Oct '17

Dear Team, After a power failure and restart, one of my instances would not display properly from the Ovirt User Portal. This error would scroll down the screen repeatly to infinitum. XFS (dm-0): Metadata CRC error detected at xfs_inobt_read_verify+0x79/0xb0 [xfs], xfs_inobt block 0x1df188 XFS (dm-0): Unmount and run xfs_repair XFS (dm-0): First 64 bytes of corrupted metadata buffer: (Hex Dump) I detached the boot disk and attached to another instance and ran xfs_repair on it, to no avail. The instance boots fine and I am able to access via XRDP. When I try to access via spice or VNC I get the error. Suggestions? Thanks

Ovirt + Cobbler + Koan ?

So I tried cobbler instead and I had it working in just a couple of hours! I'm further along today than a week of foreman's constant problems. Hooray! Here's where I am at now, if I manually configure a VM in Ovirt I can provision it from Cobbler. Great! What I would like to do is to have an easy way from Ovirt say "Grab this cobbler profile and build me a new VM with this template". In my searches on line, I haven't found anything like that. It seems the closest I'm going to get is to use Koan. However, I've not found great information for using Koan with Ovirt. My attempts so far of installing Koan on the Ovirt Management host and trying to get it to provision have all resulted in Koan trying to build a KVM _on_ the management host; not in Ovirt. Does anyone have any good documentation for setting up Cobbler integration into Ovirt? Or at least getting Koan to work with the two?

Russian translation
by Sandro Bonazzola 17 Oct '17

17 Oct '17

Hi, looking at https://translate.zanata.org/iteration/view/ovirt/ovirt-4.2?dswid=-6249 I see Russian translation is the only one under 80% for 4.2. If you have some time and know Russian, it's a good time for contributing translations.

GlusterFS performance questions
by Jayme 16 Oct '17

16 Oct '17

I am currently in the process of researching converting an existing SMB infra to virtual. Ovirt/RHEV is a strong contender and checks off a lot of boxes on our list. GlusterFS is appealing but I am finding it very difficult to find any answers or stats/numbers regarding how well it can perform as backend storage for VMs, especially VMs with medium to high workloads, and possibly some or many in a dev environment where many small files are interacted with very frequently. >From my research on GlusterFS in general some people tend to say that it is not the best performer and it's not the best choice for handling small files. How true is this? I understand that there are many variables such as hardware, drives, proper configuration, internal network etc. but what I'm trying to avoid here is going through the whole process of spendng a lot of money building out an ovirt gluster with a proper SSD glusterFS configuration w/ 10gbe internal network only to find out some day down the road that it cannot meet our I/O needs. Can anyone comment on how I can best determine the performance level to expect from a typical ovrt w/ glusterfs replica 3 arbiter 1 configuration. Or perhaps any use cases with people/companies running a similar setup in production with high VM workloads? Right now I'm leaning toward using a SAN due to the simplicity and predictable performance. Although this will definitely cost a lot more money for something that glusterFS *may* be able to handle. Thanks! James
