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.

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. Engine seems to be deployed to NFS already: [root@epycdphv02 ~]# ls -al /rhev/data-center/mnt/storage01.office.databay.de:_ovirt_engine total 23 drwxrwxrwx 3 vdsm kvm 4 Dec 3 13:01 . drwxr-xr-x 3 vdsm kvm 4096 Dec 1 17:11 .. drwxr-xr-x 6 vdsm kvm 6 Dec 3 13:09 1dacf1ea-0934-4840-bed4-e9d023572f59 -rwxr-xr-x 1 vdsm kvm 0 Dec 3 13:42 __DIRECT_IO_TEST__ NFS Mount: storage01.office.databay.de:/ovirt/engine on /rhev/data-center/mnt/storage01.office.databay.de:_ovirt_engine type nfs4 (rw,relatime,vers=4.1,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,clientaddr=192.168.1.121,local_lock=none,addr=192.168.1.3) Libvirt quemu states an error: Could not open '/var/run/vdsm/storage/1dacf1ea-0934-4840-bed4-e9d023572f59/2b1332f6-3bb6-495b-87fe-c5b85e0ac495/39d45b33-5f29-430b-8b58-14a8ea20fb08': Permission denied Even permissions of mentioned file seem to be ok.

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.

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
