Cloud-init reset network configuration to default dhcp after reboot and regular run
by Mike Lykov 06 Dec '18

06 Dec '18

Hi All! I'm trying to configure network in VMs created from template, and see strange behaviour from cloud-init. cloud-init installed and enabled in template. ver cloud-init-0.7.9-24.el7.centos.1.x86_64 guest Centos 7.5 ovirt 4.2.7 from ovirt-releases-42-pre repo 1. I use "run once" with initial run - use cloud-init - networks in-guest net iface : eth0 add new - static enter address, mask, gw ipv6 none Run (once) and cloud-init configure ifcfg-eth0 for that address (successfully). 2. I shutdown that VM and use "Run" (regular) without "use cloud init" in VM properties, awaiting that above configurations are saved (and booted with it). But because "use cloud init" not checked, and cloud-init service enabled, it start, cannot find datasource and drop configuration to default (dhcp). In cloud-init.log 2018-11-20 13:53:24,153 - util.py[WARNING]: No instance datasource found! Likely bad things to come! 2018-11-20 13:53:24,153 - util.py[DEBUG]: No instance datasource found!

Additional routes on Interface
by Sandro Emma 06 Dec '18

06 Dec '18

Hi, we are running a RHV 4.1 installation which is working fine except one issue: We have a Network which is only used for fencing(power Management via ilo), each host has an interface with this network and a custom ip, for this to work we need a few custom routes. At the moment we add the new routes via a plain route file under /etc/sysconfig/network-scripts/, but the engine flags this interface then as out-of-sync. How can we persist those changes across reboots and still be able to add new devices via the UI ? This looked promising but isnt working: https://ovirt.org/develop/release-management/features/network/networkreload… Thanks for any Help :)

The built in group Everyone is troublesome.
by Jacob Green 05 Dec '18

05 Dec '18

So all my VMs are inheriting system permissions from group everyone and giving all my users access to all my VMs, in ovirt 4.2. Is there a best practices guide or any recommendation on how to clear this up? Clicking remove on everyone does not work because Ovirt won't allow me to remove a built in account. Thank you -- Jacob Green Systems Admin American Alloy Steel 713-300-5690

Debugging "non_operational" host during self-hosted deploy
by Mikael Öhman 04 Dec '18

04 Dec '18

The "bootstrap_local_vm.yml" playbook fails at the end, during the task "Wait for the host to be up" Looking through the ovirt-hosted-engine-setup-bootstrap_local_vm log, I found the reason is supposed to be: "status": "non_operational", "status_detail": "network_unreachable", But that's it. I can't find anything wrong with any networks, neither on the host or in the partly-prepared HE VM. Is there some verbose information I can dump to find out why it thinks the network is unreachable? I can't find any logs indicating any issues until this step.

Cannot import VM. Invalid time zone for given OS type. Attribute: vm.vmStatic
by daniel＠djj-consultants.com 04 Dec '18

Need some magic here ... - 2 hosts CentOS 7.5.1804 with all the patch available, in the cluster - hosted engine from rpm ovirt-engine-appliance-4.2-20181113.1.el7.noarch with all the patch as well (manager Version 4.2.7.5-1.el7) 1) I re-install the hosts and the hosted engine from scratch 2) I imported the ISO, export and DATA domain from the SAN 3) I went to the DATA domain in the VM Import tab where I saw all the VMs 4) I imported the VM one after one BUT .... One of the VM (Windows 10 x64) can't be import because of the error in the subject of this thread. In the engine.log file I get 2018-12-01 19:17:50,387-05 WARN [org.ovirt.engine.core.bll.exportimport.ImportVmFromConfigurationCommand] (default task-4) [92c96b3c-38c5-42ab-b81c-11413ea32ccd] Validation of action 'ImportVmFromConfiguration' failed for user admin@internal-authz.

I also tried to put the DefaultWindowsTimeZone empty but engine-config doesn't allow that neither if I put a * The VM is on iscsi device so can't go see the vm files to fix it directly on the fs 10 hours since I start to fix this import thing ;-( If someone has some magic for me, I will be a nice gift before christmas

[OT] Xen/Oracle VM under Qemu-kvm/oVirt
by Gianluca Cecchi 04 Dec '18

04 Dec '18

Hello, I have to do a test on Oracle VM 3.4.4 that is based on Xen 4.4.4. The test aims in simulating storage migration in OVM, where I have to migrate also the so called server pool file system, that requires a special procedure. I see that some guys wrote here to ask about OVM to oVirt migrations, so there could be some expertise in this field. I'm just trying to proceed with the hypervisor steps (Oracle VM Server), that is the more difficult part, I suppose. I'm testing at the moment on a Fedora 29 system, using qemu-kvm, setting host-pass-through for the vm dedicated to the Oracle VM Hypervisor. I already tested nested virtualization (with oVirt for some vms) inside this system, so the host part should be ok. I have set disks as scsi and vnic as e1000 Installation gone ok but at reboot I see cpu stuck and no prompt yet see here: https://drive.google.com/file/d/1sAEO-W0-OLIGSugxIwSLRBx3WXXoK1yx/view?usp=… I have not yet understood exactly the reason of complain... Any one already able to create a Xen (or Oracle VM) nested environment inside qemu-kvm? The OS of the Xen dom0 should be based on Oracle Linux 6.x I can also test trying to install on oVirt if anyone on the list already ran through this path. Thanks in advance for any help or pointers. I'm also going and post on Oracle VM forum... Gianluca

Best Openstack version to integrate with oVirt 4.2.7
by Gianluca Cecchi 04 Dec '18

04 Dec '18

Hello, do you think it is ok to use Rocky version of Openstack to integrate its services with oVirt 4.2.7 on CentOS 7? I see on https://repos.fedorapeople.org/repos/openstack/ that, if Rocky is too new, between the older releases available there are, from newer to older: Queens Pike Ocata Newton At the moment I have two separate lab environments: oVirt with 4.2.7 Openstack with Rocky (single host with packstack allinone) just trying first integration steps with these versions, it seems I'm not able to communicate with glance, because I get in engine.log 2018-11-10 17:32:58,386+01 ERROR [org.ovirt.engine.core.bll.provider.storage.AbstractOpenStackStorageProviderProxy] (default task-51) [e2fccee7-1bb2-400f-b8d3-b87b679117d1] Not Found (OpenStack response error code: 404) Nothing in glance logs on openstack, apparently. In my test I'm using http://xxx.xxx.xxx.xxx:9292 as provider url checked the authentication check box and glance user with its password 35357 as the port and services as the tenant a telnet on port 9292 of openstack server from engine to openstack is ok similar with cinder I get: 2018-11-10 17:45:42,226+01 ERROR [org.ovirt.engine.core.bll.provider.storage.AbstractOpenStackStorageProviderProxy] (default task-50) [32a31aa7-fe3f-460c-a8b9-cc9b277deab7] Not Found (OpenStack response error code: 404) So before digging more I would lile to be certain which one is currently the best combination, possibly keeping as fixed the oVirt version to 4.2.7. Thanks, Gianluca

From Self-hosted engine to standalone engine
by Punaatua PK 04 Dec '18

04 Dec '18

Hello, we currently have a self-hosted engine on gluster with 3 hosts. We want to have the engine on a single machine on a standalone KVM. We did the following steps on our test platform. - Create a VM on a standalone KVM - Put the self hosted engine into global maintenance - Shut the self-hosted engine - Copy the self-hosted engine image disk (by browsing into the gluster engine volume) by using linux dd command to the standalone KVM - Reusing the self-hosted engine's MAC address on the new standalone VM - Starting the standalone VM which use the self-hosted image disk previously copied on the standalone KVM - Log in the engine and then undeploy the hosted-engine by re-installing all the host and go for UNDEPLOY on the self-hosted section - Stop ovirt-ha-agent and ovirt-ha-broker Everything seems to be ok for now. What do you think about our process ? (to go from self-hosted to standalone) Do you have any idea on what should be checked ? Thank you (We wanted to go out from self-hosted engine, because we don't really master this deployment)

FCoE wont initialize on reboot oVirt 4.2.
by Jacob Green 03 Dec '18

03 Dec '18

I have HP BL460c Gen9 blades with BCM57840 NetXtreme II 10/20-Gigabit Ethernet via a HP Virtual connection. In my ovirt 4.1 environment I have fibre channel working great. However in the new environment that I want to bring the data domain over too ultimately, I am having issues with ovirt interfering with the hosts ability to see the Fiber Channel storage. If i build a clean CentOS 7 installation and get my FCoE module installed and Fiber channel set up on my appropriate interfaces, it works and sees the fiber channel interface every time I type fcoeadm -i, I can reboot a million times, does not go away. However once I turn it into a oVirt 4.2 node and add it to my environment and reboot the blade it is hit or miss if fcoeadm -i is going to return interface information. If I then type "systemctl restart network" my fiber channel comes online, but I should not need to do this. I can see in my dmesg logs that the fiber channel is initializing on boot. [ 39.465578] cnic: QLogic cnicDriver v2.5.22 (July 20, 2015) [ 39.465594] bnx2x 0000:06:00.2 eno51: Added CNIC device [ 39.475618] bnx2x 0000:06:00.3 eno52: Added CNIC device [ 39.495575] bnx2fc: QLogic FCoE Driver bnx2fc v2.11.8 (October 15, 2015) [ 39.505971] bnx2fc: bnx2fc: FCoE initialized for eno52.

However that should not keep the fiber channel interfaces from coming up... And I need to know its working before I do that.

The host is running latest ovirt-node-ng 4.2.7. hosted-engine --deploy fails constantly in late stage when trying to run engine from NFS.

Cannot remove old renamed hosted-engine storage domain
by Andrew DeMaria 03 Dec '18

03 Dec '18

Hi, I've been testing the hosted-engine restore process and have gotten stuck because I cannot remove the old hosted-engine storage domain. Here is the process I went through: 1. Setup two 70G luns under an iscsi target (one for the original, one for the restored hosted-engine. They are both empty at this point) 2. Install RHEL 7.6 on two other hosts (synergy and pointblank) 3. Install ovirt 4.2 on host synergy thru hosted-engine --deploy using one of the luns 4. Add host pointblank 5. Perform engine-backup and copy it off 6. Shutdown both RHEL hosts 7. Reinstall RHEL on both (wipe disk) 8. Install ovirt 4.2 on host synergy via hosted-engine --deploy --restore-from-file=backup.tgz using the other unused lun 9. Remove old host pointblank 10. Add host pointblank 11. Noticed that old hosted-engine storage domain (named hosted_storage_old_20181130T111054) is designated the master storage domain 12. Move storage domain hosted_storage_old_20181130T111054 into maintenance 13. Noticed that hosted_storage_old_20181130T111054 is still the master (even after moving it into maint while the new hosted_storage storage domain is healthy/active) 14. Tried to detach hosted_storage_old_20181130T111054 anyways, but presented with: Error while executing action: Cannot detach the master Storage Domain from the Data Center while there are other storage domains attached to it. -Please try to activate another Storage Domain in the Data Center. This is quite strange as the new hosted_storage storage domain is listed under that same Data Center named "Default" and is shown active. Any guidance would be much appreciated! Thanks, Andrew

hosted-engine deploy seems to be failed, but it is not
by Sinan Polat 03 Dec '18

03 Dec '18

Hi folks, A while ago I installed oVirt 4.2 on my CentOS 7.5 server. It is a single node. Everything is working, I can deploy VM's, etc. But it look likes that the hosted-engine is partly installed or something. [root@s01 ~]# hosted-engine --vm-status It seems like a previous attempt to deploy hosted-engine failed or it's still in progress. Please clean it up before trying again [root@s01 ~]# Any suggestions? Thanks! Sinan

cluster 4 pc's for more scanning power?
by Peter C. 03 Dec '18

03 Dec '18

Hello and sorry for the ignorance behind this question. I've been reading about various scale out, "hyper convergence" solutions and want to ask this about oVirt. I do vulnerability scanning on my company's assets. I do it from an obsolete laptop that was given to me. The load goes over 13 sometimes, and the scans take a long time. If I built an oVirt cluster from 4 or 5 desktop pc's, build VM to run OpenVAS, would the cpu load demanded by the scanning be spread accross the 3-4 hosts, not inlcuding the management host, and therby give my scans more CPU power? If not oVirt, is there another project that would be better suited to what I'm trying to achieve? Qualifiers: -I'm not asking if this is the best way to get high-load scanning done. I'm just asking if I'll get the combined power from the cpu cores of all the host machines. The scanning jobs thread already. -I know it would probably be more efficient to get a powerful multi core workstation or server to do this. That is not my question. -The pc's are perfectly good, they are just not being used and won't be used for anything else. Thanks in advance.

SPICE QXL Crashes Linux Guests
by Alex McWhirter 03 Dec '18

03 Dec '18

I'm having an odd issue that i find hard to believe could be a bug, and not some kind of user error, but im at a loss for where else to look. when booting a linux ISO with QXL SPICE graphics, the boot hangs as soon as kernel modesetting kicks in. Tried with latest debian, fedora, and centos. Sometimes it randomly works, but most often it does not. QXL / VGA VNC work fine. However if i wait a few minutes after starting the VM for the graphics to start, then there are no issues and i can install as usual. So after install, i reboot, hangs on reboot right after graphics switch back to text mode with QXL SPICE, not with VNC. So i force power off, reboot, and wait a while for it to boot. If i did text only install, when i open a spice console it will hang after typing a few characters. If i did a graphical install then as long as i waited long enough for X to start, then it works perfectly fine. I tried to capture some logs, but since the whole guest OS hangs it's rather hard to pull off. I did see an occasional error about the mouse driver, so that's really all i have to go on. As for the spice client, im using virt-viewer on windows 10 x64, tried various versions of virt-viewer just to be sure, no change. I also have a large amount on windows guests with QXL SPICE. These all work with no issue. Having guest agent installed in the linux guest seems to make no difference. There are no out of the ordinary logs on the VDSM hosts, but i can provide anything you may need. It's not specific to any one host, i have 10 VM hosts in the cluster, they all do. They are westmere boxes if that makes a difference. Any ideas on how i should approach this? VNC works well enough for text only linux guest, but not being able to reboot my GUI linux guests without also closing my spice connection is a small pain. as far as ovirt versions im on the latest, this is a rather fresh install. just set it up a few days ago, but i've been a long time ovirt user. I am using a squid spice proxy if that makes a difference.

Out of sync, hosts network config differs from DC

Property: default route, host - true, DC - false I have 4 nics. bond0 = 2 x 10g eno1 = ovirtmgmt eno2 = for vm traffic. eno2 says it's out of sync, hosts network config differs from DC, default route: host - true, DC - false. I have tried "sync all networks" but the message still remains See attached. Where can I look to fix the issue?

UPS with USB Support
by florentl 30 Nov '18

30 Nov '18

Hi everybody, I'm currently setting up an ovirt solution. I have three servers with glusterfs. They run hosted engine. I configured the power management of the node for using idrac agent (I have Dell servers). The communication is ok but I don't really know if configuring power management is very usefull with only three servers. My three servers are powered via an ups which have only one usb port. I'm wondering what is the best option to shutdown the datacenter in case of power failure. I have read in previous posts that I have to write a script. So I think I'm going to : - install apcupsd on the node connected with the ups via usb - configure apcupsd.conf to lanch a script and send a mail - write a script to shutdown properly all the wm and to put the datacenter in maintenance mode What do you think about this solution ? Is there a better way to manage the vm's and datacenter's shutdown with the power management solution associated with ovirt host ? Regards, Florent

oVirt Node on CentOS 7.5 and AMD EPYC Support
by Tobias Scheinert 30 Nov '18

30 Nov '18

Hi, I am currently building a new virtualization cluster with oVirt, using AMD EPYC processors (AMD EPYC 7351P). At the moment I'm running oVirt Node Version 4.2.3 @ CentOS 7.4.1708. We have the situation that the processor type is recognized as "AMD Opteron G3". With this type of instruction set the VMs are not able to do AES in hardware, this results in poor performance in our case. I found some information that tells me that this problem should be solved with CentOS 7.5 --> <https://access.redhat.com/errata/RHEA-2018:1488> My actual questions: - Are there any further information about the AMD EPYC support? - Any information about an update of the oVirt node to CentOS 7.5? Greeting Tobias
