Use public-signed SSL certs?
by Chris Adams 02 Aug '19

02 Aug '19

I installed an SSL cert from a public CA (Let's Encrypt) on my engine, following this: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/ht… That gets the regular web UI working, but I can't upload an ISO. I assume that I need to do something with the imageio-proxy service on the engine, but not sure what... I tried replacing imageio-proxy.cer and imageio-proxy.key.nopass, but that didn't work. I'm trying to avoid ever needing to install a special CA cert in browsers. -- Chris Adams <cma(a)cmadams.net>

Re: Manual Migration not working and Dashboard broken after 4.3.4 update
by Strahil 02 Aug '19

I'm not sure, but I always thought that you need an agent for live migrations. You can always try installing either qemu-guest-agent or ovirt-guest-agent and check if live migration between hosts is possible. Have you set the new cluster/dc version ?

no network interface
by A S 01 Aug '19

01 Aug '19

Hi. I had ovirt running with a VM but it suddenly broke. I wiped it all and did a reinstall but now I am not able to connect my host to the network. the host is always saying status='unassigned'. in the network page where I would drag and drop a connection, there is no interface to connect to. its this page https://ovirt.org/images/wiki/SetupNetworksNew.png?1478101462 but there is nothing in the interfaces column on the left Can anyone point me in the right direction to fix this? Thanks I have only one machine with the engine and host on it.

Trouble initializing new VM in 4.2.8.2-1.el7
by David Johnson 30 Jul '19

Good evening, Thanks in advance, I'm trying to set up a new VM in my cluster, and things appear to have hung up initializing the 80GB boot partition for a new Windows VM. The system has been sitting like this for 6 hours. What am I looking for to resolve this issue? Can I kill this process safely and start over?

Moving data to new storage appliance
by David Johnson 30 Jul '19

30 Jul '19

Hi everyone, I'm sorry to bother y'all with another noob question. We are in the process of retiring the old storage appliance that backed our oVirt cluster in favor of a new appliance. I have migrated all of the active VM storage to the new appliance, but can't see how to migrate the "base versions". My understanding is that if I just drop the storage with the base versions then the derived VM's will cease to be functional. Please advise.

Great. Storage domain attached, templates imported and the only VM defined at source correctly started (at source I configured link down for the VM, inherited at target, so no collisions). Elapsed between beginning of ovirt connection, until first template import has been about 6 minutes. ...

I'm using EQL that doesn't support bonding and has one portal that all initiators use. So in my primary env I configured "iSCSI Multipathing" tab in Compute --> Datacenter --> Datacenter_Name window. But this tab appears only when you activate the storage. So during the ansible playbook run the iSCSI connection has been activated through the "default" iscsi interface I can then: - configure "iSCSI Multipathing" - shutdown VM - put host into maintenance - remove the default iSCSI session that has not been removed on host iscsiadm -m session -r 6 -u - activate host now I have: [root@ov201 ~]# iscsiadm -m session tcp: [10] 10.10.100.8:3260,1 iqn.2001-05.com.equallogic:4-771816-99d82fc59-5bdd77031e05beac-ovsd3910 (non-flash) tcp: [9] 10.10.100.8:3260,1 iqn.2001-05.com.equallogic:4-771816-99d82fc59-5bdd77031e05beac-ovsd3910 (non-flash) [root@ov201 ~]# with # multipath -l 364817197c52fd899acbe051e0377dd5b dm-29 EQLOGIC ,100E-00 size=1.0T features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=0 status=active |- 23:0:0:0 sdb 8:16 active undef running `- 24:0:0:0 sdc 8:32 active undef running - start vm The I do a cleanup: 1.

The mac address is the one defined in my target engine, that is different from source engine to avoid overlap of mac adresses Is this an option I can customize? In general a VM could have problems when changing its mac address... 3) Clean up dest DC after "discreet failover test" The guide says: 1. Detach the storage domains from the secondary site. 2. Enable storage replication between the primary and secondary storage domains. better to also restart the DR hosts? 4) VM consistency Can we say that all the imported VMs will be "crash consistent"? Thanks, Gianluca

Clone function seem broken - regarding disk virtual size
by Vrgotic, Marko 26 Jul '19

26 Jul '19

Dear oVirt, All our CentOS templates are “baked” with 40GB disk (sparse) QCOW. When Creating new VM from template, using Thin storage allocation: * VM is created with 40GB disk (reading from oVirt GUI) and * from OS fdisk and/or parted report 40GB disk size. * The / partition is also matching expected size When Creating VM from template, using default Clone storage allocation: * VM is created with 40GB disk (reading from oVIrt GUI) * However: * from OS fdsik and/or parted report only actual used space, which in our case is 8GB. * The / partition is matching only actual disk size, not virtual one Why is Clone not taking into account Virtual size of the Template disk? Is it intended behavior that when image is cloned from template, only actual disk size information is copied, not the virtual? Please assist. Kindly awaiting your reply. oVirt 4.3.4 with SHE and NFS based storage and Local. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic Sr. System Engineer @ System Administration m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> tel. +31 (0)35 677 4131 ActiveVideo BV Mediacentrum 3741 Joop van den Endeplein 1 1217 WJ Hilversum

Hosted Engine VM - CPU and Memory Sizing
by paul.christian.suba＠cevalogistics.com 25 Jul '19

Hi, Is there a recommended CPU and memory size for the Hosted Engine VM? We have what started as a 4 node physical cluster lab with 4 vms that has now grown to 44vms. The dashboard is slow to load information and the HE VM is consistently seen with 99% CPU with the breakdown below. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 12076 postgres 20 0 506516 276172 143772 R 99.3 1.7 206:17.15 postmaster 10337 postgres 20 0 484756 254156 144000 R 99.0 1.6 179:52.35 postmaster 38603 postgres 20 0 500068 267836 143992 S 70.1 1.6 528:04.13 postmaster 49217 postgres 20 0 468736 235484 143624 S 19.3 1.4 41:57.55 postmaster 5569 ovirt 20 0 6430912 2.3g 6368 S 1.3 14.5 894:20.75 java We used the default 4 CPU and 16 GB RAM. This is oVirt 4.3.1. I am curious to find out as well if the postgres processes using 99% CPU is normal?

According to another post in the mailing list, the Engine Hosts (that has ovirt-ha-agent/ovirt-ha-broker running) is checking http://{fqdn}/ovirt-engine/services/health As the IP is changed, I think you need to check the URL before and after thr mifgration.

Active-Passive DR: mutual for different storage domains possible?
by Gianluca Cecchi 25 Jul '19

25 Jul '19

Hello, suppose I want to implement Active-Passive DR between 2 sites. Sites are SiteA and SiteB. I have 2 storage domains SD1 and SD2, that I can configure so that SD1 is active in storage array installed in SiteA with replica in SiteB and SD2 the reverse. I have 4 hosts: host1 and host2 in SiteA and host3 and host4 in SiteB. I would like to optimize compute resources and workload so that: oVirt env OV1 with ovmgr1 in SiteA (external engine) is composed by host1 and host2 and configured with SD1 oVirt env OV2 with ovmgr2 in SiteB (external engine) is composed by host3 and host4 and configured with SD2. Can I use OV2 as DR for OV1 for VMs installed on SD1 and at the same time OV1 as DR for OV2 for VMs installed on SD2? Thanks in advance, Gianluca Cecchi

iSCSI-based storages won't login to the portals with all IPs on reboot
by nicolas＠devels.es 25 Jul '19

25 Jul '19

Hi, We're running oVirt 4.3.2. Currently, we have one storage backend (cabinet) with two controllers, each of them with 2 network interfaces (4 network interfaces in total). When we added the Storage Domain, we discovered the target for each of the 4 IPs and marked the LUN so it would be added with 4 different IPs. When we put a host on maintenance, all the paths are deactivated, and when we activate it back it discovers all the 4 paths for the storage backend. However, if we reboot the host, on activation it only activates one path. We can see this running 'multipath -ll'. We can manually activate the rest of the paths using this command for each of the IPs: # iscsiadm --mode discovery --type sendtargets --portal 10.X.X.X --login However, we wonder why oVirt wouldn't log into each of the IPs upon a boot. Is there something we're missing? Can this be fixed manually? Currently we're running a script on boot that will issue the command above for each of the IPs of the cabinet. Thanks for any help!

template permissions not inherited (4.3.4)
by Timmi 24 Jul '19

24 Jul '19

Hi oVirt List, I have just a quick question if I should open a ticket for this or if I'm doing something wrong. I created a new VM template with specific permissions in addition to the system wide permissions. If I create a new VM with the template I notices that only system permissions are copied to the permission of the new VM. Is this the intended behavior? I was somehow under the impression that the permission from the template should have been copied to the newly created VM. Tested with Version 4.3.4.3-1.el7 Best regards Christoph

Hi All, What is the way if self hosted engine corrupted in any environment and we need to setup it from scratch however on the new engine we need the same hosts and virtual machine without loosing data. Thanks Shashakn

Hi, after a blackout one host of my ovirt not working properly. I tried to Reinstall it but ends with the following error "Failed to install Host ov1. Failed to execute stage 'Closing up': Failed to start service 'vdsmd'." I tried to start manually but it not start . Now, I would like to reinstall from iso ovirt node. After I put the host is in maintenance must I remove host from the cluster (Hosts -> host1 -> Remove) or I can reinstall without remove it? If I remore it from the cluster the network configurations I lose them or not? My ovirt version is oVirt Engine Version: 4.1.9.1-1.el7.centos.

Re: Storage domain 'Inactive' but still functional

I forgot to mention that LVM config has to be modified in order to 'inform' local LVM stack to rely on clvmd/dlm for locking purposes. Yet, this brings abother layer of complexity which I prefer to avoid , thus I use HA-LVM on my pacemaker clusters. @Martin, Check the link from Benny and if possible check if the 2 cases are related.

In this case, there was a lot of activity on all storage domains, because I'm moving all my storage (> 10TB in 185 disk images) to a new storage platform. During the online move of one the images, the metadata checksum became corrupted and the storage domain went offline. >>> >>> Of course, I could dig up the engine logs and vdsm logs of when it happened, but that would be some work and I'm not very confident that the actual cause would be in there. >>> >>> If any oVirt devs are interested in the logs, I'll provide them, but otherwise I think I'll just see it as an incident and move on. >>> >>> Best regards, >>> Martijn. >>> >>> >>> >>> >>> On Jul 22, 2019 10:17, Martijn Grendelman <Martijn.Grendelman(a)isaac.nl> wrote: >>>>> >>>>> Hi, >>>>> >>>>> Thanks for the tips!

That allowed me to perform the restore without bringing all VMs down, which was important to me, because if I had to shut down VMs, I was sure I wouldn't be able to restart them before the storage domain was back online. >>>>> >>>>> Of course this is a more a Linux problem than an oVirt problem, but oVirt did cause it ;-) >>>>> >>>>> Thanks, >>>>> Martijn. >>>>> >>>>> >>>>> >>>>> Op 19-7-2019 om 19:06 schreef Strahil Nikolov: >>>>>> >>>>>> Hi Martin, >>>>>> >>>>>> First check what went wrong with the VG -as it could be something simple. >>>>>> vgcfgbackup -f VGname will create a file which you can use to compare current metadata with a previous version. >>>>>> >>>>>> If you have Linux boxes - you can add disks from another storage an
