Engine ISO Uploader - SSL Peer Not Trusted
by Shawn Weeks 17 Nov '18

17 Nov '18

Trying to upload an iso using engine-iso-uploader on a hosted-engine instance and I'm getting an SSL Error. I followed the directions at https://www.ovirt.org/documentation/admin-guide/appe-oVirt_and_SSL/ to setup SSL and am able to login to the Admin console without an issue. Also checked that things like curl recognize the CA correctly. Not sure where engine-iso-uploader is getting it's trust store. [root@cloud ~]# engine-iso-uploader list Please provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort): ERROR: Unable to connect to REST API at https://cloud.dev.example.com:443/ovirt-engine/api due to SDK error Message: Error while sending HTTP request: (60, "Peer's certificate issuer has been marked as not trusted by the user.") What am I missing? Thanks Shawn

how to allow VM to query external DHCP server
by Jarosław Prokopowski 16 Nov '18

Hi, It seems my VMs are not able to send DHCP requests to external DHCP server located in the same network as oVirt hosts. Can anyone tell me how I can enable this? Thanks Jarek

oVirt monitoring
by b.yuri8＠gmail.com 16 Nov '18

16 Nov '18

Hello, I'm trying to do some performance monitoring on our oVirt and want to ask if someone has any experience with it? Currently I'm trying Red Hat Virutalization tool which has REST API, where you can get statistics per host, vm, disk and nic. Problem is that you cannot get any historical data via rest api (at least I didn't find any way to do it) and almost all metrics are gauge values over some interval (couldn't find it documentation, but it looks like they are updated every 15 s). I surely don't want to query whole environment every 15 seconds and missing some values is also not an option since I could miss some spikes in performance. Any help is appreciated! George

OVS and Ovirt integration questions
by 0pk0de＠riseup.net 16 Nov '18

16 Nov '18

Hello, After having integrated OVS with Ovirt and enabled it as default network provider I am facing the following issues. I can see with "ovs-vsctl show" that the virtual switch / bridge called "br-int" is created. I can see interfaces being added / removed to it as I start / stop VMs. [root@******* ~]# ovs-vsctl show 78e883f9-f074-4292-afce-bb829ded856b Bridge br-int fail_mode: secure Port "vnet6" Interface "vnet6" Port br-int Interface br-int type: internal Port "vnet4" Interface "vnet4" ovs_version: "2.9.0" Now I for example want to create a new interface as shown: ip tuntap add mode tap sniff0 ovs-vsctl add-port br-int sniff0 -- --id=@p get port sniff0 -- --id=@m create mirror name=m0 select-all=true output-port=@p -- set bridge br-int mirrors=@m fae36943-2ca7-4914-9679-0b881cd062d8 Its created, but how do I assign this sniffing interface to a ovirt VM? also, how can I create sniffing ports listening only on a subset of interfaces if they get dynamically created / removed? vnet6 points to host A now, but after shutting it down starting a few other VMs it will point to host B... How do I control to what vm the vnetX nic gets assigned?

Foreman integration / Network integration (storage)
by jeanbaptiste＠nfrance.com 16 Nov '18

16 Nov '18

Hello everybody, I use oVirt with Foreman to bare metal provision hypervisor. On foreman side, I use excellent Discovery plugin firstly. Afterthat I configure a "bond0" lagg on Network host tab. Into this bond0, I create some "virtual interface" (bond0.15 for example) with a static IP assignation via integrated Foreman IPAM. All is pretty cool, but after oVirt installation is done, I'm "forced" via postinstall to apply: Add "NM_Controlled=no" to all my bond0.* interfaces. Afterthat on oVirt , Host, "Setup Host Network", I'm able to move my network to the host and have automatically the IP address "configured" since read from the ifcfg file. This method seem to work but only in "one time mode". There is no real link between oVirt and Foreman for IP assignement. Do you use anothers way to provision bare metal hypervisor and have automatic IP assignement (for storage network for ex) between these two excellent tools ? thanks !

using vlan-tagged nic for ovirtmgmt
by Tony Brian Albers 16 Nov '18

16 Nov '18

Is this possible? I have 3 hosts with each four physical interfaces. On one of them, I have a vlan defined which I'd like to use for ovirtmgmt. However, after installing the host, it says that the ovirtmgmt network is missing on it and if I try to assign ovirtmgmt I can only do it on the physical NIC's Any ideas? /tony -- -- Tony Albers Systems Architect Systems Director, National Cultural Heritage Cluster Royal Danish Library, Victor Albecks Vej 1, 8000 Aarhus C, Denmark.

Engine login fails after previously working.
by Jeremy Tourville 16 Nov '18

16 Nov '18

I recently completed setup for 389 DS and ovirt-engine-extension-aaa-ldap-setup. I was able to complete the script run without errors and could perform both login and search functions without issue. Initially after setup I was able to login. After getting all this to work I had rebooted the 389 DS server. I tried to login as the super user I created earlier. I am getting the message "Unable to login. Verify your login information or contact the system administrator." This issue only seemed to happen after the reboot, prior to that it had been working. Any thoughts on troubleshooting? Thanks in advance.

VM import using wrong/slower interface. help/question.
by Jacob Green 15 Nov '18

15 Nov '18

Currently I have a host that has multiple network connections. 1 bonded 20Gigabit connect and a couple of 1 gig Ethernet connections. Then my export storage domain is on a storage device on a vlan we can call vlan B. Today I was exporting a VM from one environment to another, and after I reattached the export domain and started importing I noticed an even message for one of my hosts, it looked like the following. "Host A has network interface which exceeded the defined threshhold [95%] (eno3: transmit rate [8%], receive rate [98%])" So when I take a look at that hosts interfaces in the OVIRTENGINE gui I can confirm that it is exceeding 900Mbits on that interface. The problem/question is this. I have the migration network set as well as the ovirtmgmt network on the 20Gigabit interface. The only network profile attached to ENO 3 is VLAN-B and only VM traffic on that profile. So why is it using that eno3 interface instead of the ovirtmgmt interface on the 20Gigabit interface to import the VM? So I do have at least one theory, the storage solution is also on VLAN B the same VLAN that eno3 rides on, but I am of the understanding that Ovirt should be instructing the host to use the migration network, which in my case is also my ovirtmgmt network on the 20Gigabit interface. It matters because my storage is also on a 20Gigabit bond and these imports would be a lot faster if it was using the correct network to the host to import the VM. I hope my question is clear enough, I would provide screenshots but the ovirt-users mailing lists scrubs those. Basically can I instruct or force ovirt to import VMs over my 20Gigabit interface instead of the slower 1Gig interface that is hooked up. Thank you. -- Jacob Green Systems Admin

corrupted hosted engine
by Jarosław Prokopowski 15 Nov '18

15 Nov '18

Hi, It looks like after host restart my hosted engine VM is not accessible any more. The storage is glusterfs. The gluster volume is healthy. The VM status is: {"reason": "failed liveliness check", "health": "bad", "vm": "up", "detail": "Up"} hosted-engine --console The engine VM is running on this host Connected to domain HostedEngine Escape character is ^] error: internal error: cannot find character device <null> I tried to boot it from cdrom by changing vm.conf file and I'm not sure if the syntax is correct: 1. I removed bootOrder:1 from the index:0 device devices={index:0,iface:virtio,format:raw,address:{type:pci,slot:0x07,bus:0x00,domain:0x0000,function:0x0},volumeID:8d823e33-4260-4004-a468-cf477d7b1f5b,imageID:41342181-5c8f-4544-878b-44fdaa40dddc,readonly:false,domainID:beb954e7-61b7-4437-bd21-4b268e1a26e5,deviceId:41342181-5c8f-4544-878b-44fdaa40dddc,poolID:00000000-0000-0000-0000-000000000000,device:disk,shared:exclusive,propagateErrors:off,type:disk} 2. in index:2 device I addedd bootOrder:1 and path to the iso image: devices={index:2,iface:ide,shared:false,readonly:true,bootOrder:1,deviceId:8c3179ac-b322-4f5c-9449-c52e3665e0ae,address:{controller:0,target:0,unit:0,bus:1,type:drive},device:cdrom,path:/opt/iso/CentOS-7-x86_64-DVD-1804.iso,type:disk} The outcome is the same - no console connection. Now I also get: hosted-engine --vm-start Command VM.getStats with args {'vmID': '1e3aa9cf-8708-40a0-bc86-1127df01047a'} failed: (code=1, message=Virtual machine does not exist: {'vmId': u'1e3aa9cf-8708-40a0-bc86-1127df01047a'}) Unfortunately I do not have any backup. Is there a way to redeploy hosted engine and import current configuration or any other way to fix it?
