[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

Hello Team, We are running a setup of 3-way replica HC gluster setup configured during the initial deployment from the cockpit console using ansible. NODE1 - /dev/sda (OS) - /dev/sdb ( Gluster Bricks ) * /gluster_bricks/engine/engine/ * /gluster_bricks/data/data/ * /gluster_bricks/vmstore/vmstore/ NODE2 and NODE3 with a similar setup. Hosted engine was running on node2. - While moving NODE1 to maintenance mode along with stopping the gluster service as it prompts before, Hosted engine instantly went down. - I start the gluster service back on node1 and start the hosted engine again and found hosted engine started properly but getting crashed again and again within frames of second after a successful start because HE itself stopping glusterd on node1. (not sure) but cross-verified by checking glusterd status. *Is it possible to clear pending tasks or not let the HE to stop glusterd on node1?* *Or we can start the HE using other gluster node?* https://paste.fedoraproject.org/paste/Qu2tSHuF-~G4GjGmstV6mg -- ABHISHEK SAHNI IISER Bhopal

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.

[ 39.516654] bnx2fc: [06]: FCOE_INIT passed Reminder I have not added a FC storage domain yet, because I need to turn off and detach the domain from the old 4.1 environment first. However that should not keep the fiber channel interfaces from coming up... And I need to know its working before I do that. Below is what an fcoeadm -i should return when it seems to be working. ____________________________________________________________________________________________________ fcoeadm -i Description: BCM57840 NetXtreme II 10/20-Gigabit Ethernet Revision: 11 Manufacturer: Broadcom Limited Serial Number: 5CB901C7EE00 Driver: bnx2x 1.712.30-0 Number of Ports: 1 Symbolic Name: bnx2fc (QLogic BCM57840) v2.11.8 over eno51 OS Device Name: host10 Node Name: 0x50060b0000c27a05 Port Name: 0x50060b0000c27a04 Fabric Name: 0x1000c4f57c218ff4 Speed: unknown Supported Speed: 1 Gbit, 10 Gbit MaxFrameSize: 2048 bytes FC-ID (Port ID): 0x0a025c State: Online Description: BCM57840 NetXtreme II 10/20-Gigabit Ethernet Revision: 11 Manufacturer: Broadcom Limited Serial Number: 5CB901C7EE00 Driver: bnx2x 1.712.30-0 Number of Ports: 1 Symbolic Name: bnx2fc (QLogic BCM57840) v2.11.8 over eno52 OS Device Name: host11 Node Name: 0x50060b0000c27a07 Port Name: 0x50060b0000c27a06 Fabric Name: 0x1000c4f57c21979d Speed: unknown Supported Speed: 1 Gbit, 10 Gbit MaxFrameSize: 2048 bytes FC-ID (Port ID): 0x14037b State: Online ____________________________________________________________________________________________________ However if I reboot the node from the ovirt console and wait a few minutes after it has rebooted then type fcoeadm -i I get the following. fcoeadm -i fcoeadm: No action was taken Try 'fcoeadm --help' for more information. it is not until I perform a systemctl restart network, that I get the correct output from above. Any help or insight into fiber channel with ovirt 4.2 would be greatly appreciated. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690

hosted-engine --deploy fails on Ovirt-Node-NG 4.2.7
by Ralf Schenk 03 Dec '18

Hello, I try to deploy hosted-engine to a NFS Share accessible by (currently) two hosts. 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. It already ran as "HostedEngineLocal" and I think is then migrated to NFS storage.

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.
