oVirt 4.3.3 - servers cannot be reached
by Wood Peter 02 May '19

02 May '19

Hi, I setup AD authentication and from command line all looks good. Unfortunately, on the Web UI users sometimes login successfully but most of the times the login screen just hangs and after 2-3 min. it displays "Unable to log in because servers cannot be reached. Try again later." In engine.log I see this: 2019-05-02 11:12:11,581-07 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-72) [] EVENT_ID: USER_VDC_LOGIN_FAILED(114), User peter(a)ad.mycompany.com connecting from '10.12.29.48' failed to log in : 'Unable to log in because servers cannot be reached. Try again later.'. 2019-05-02 11:12:11,583-07 ERROR [org.ovirt.engine.core.sso.servlets.InteractiveAuthServlet] (default task-68) [] Cannot authenticate user 'peter(a)ad.mycompany.com' connecting from '10.12.29.48': Unable to log in because servers cannot be reached. Try again later. Even when my login attempt on the Web UI is hanging I can still successfully run the login test from shell: ovirt-engine-extensions-tool aaa login-user --profile=ad.mycompany.com --user-name=peter The above command never fails. That makes me wonder why am I getting the "servers cannot be reached" error? I assume the AD servers cannot be reached but from the command line it works perfect every time. Any idea what could be the problem or where to look for the error. Thank you, -- Peter

Prevent Gluster Volume being monitored by oVirt
by smirta＠gmx.net 02 May '19

02 May '19

Dear all We are running a oVirt GlusterFS hyperconverged setup with arbiter version 4.2.6.4-1.el7 here. It looks like we are affected by this bug https://bugzilla.redhat.com/show_bug.cgi?id=1614430 with one or more gluster volumes that are not storage domains of oVirt. Is there a way to exclude them from monitoring (vdsm-gluster) or to prevent being added to the engine's database? Thanks Simon

Re: Stale hosted engine node information harmful ?
by Strahil 02 May '19

02 May '19

In a Red Hat Solution , it is recommended to restart ovirt-ha-agent & ovirt-ha-broker. I usually set the global maintenance and wait 20s-30s . Then I just stop on all nodes ovirt-ha-agent.service & ovirt-ha-broker.service . Once everywhere is stopped, start the 2 services on all nodes and wait 4-5min. Last verify the status from each host, before removing global maintenance.

Re: All hosts non-operational after upgrading from 4.2 to 4.3

Are you able to access your iSCSI via the /rhev/data-center/mnt... mount point ? Best Regards, Strahil NikolovOn Apr 5, 2019 19:04, John Florian <jflorian(a)doubledog.org> wrote: > > I am in a severe pinch here. A while back I upgraded from 4.2.8 to 4.3.3 and only had one step remaining and that was to set the cluster compat level to 4.3 (from 4.2). When I tried this it gave the usual warning that each VM would have to be rebooted to complete, but then I got my first unusual piece when it then told me next that this could not be completed until each host was in maintenance mode. Quirky I thought, but I stopped all VMs and put both hosts into maintenance mode. I then set the cluster to 4.3. Things didn't want to become active again and I eventually noticed that I was being told the DC needed to be 4.3 as well. Don't remember that from before, but oh well that was easy. > > However, the DC and SD remains down. The hosts are non-op. I've powered everything off and started fresh but still wind up in the same state. Hosts will look like their active for a bit (green triangle) but then go non-op after about a minute. It appears that my iSCSI sessions are active/logged in.

oVirt and Ceph iSCSI: separating discovery auth / target auth ?
by Matthias Leopold 01 May '19

01 May '19

Hi, I'm trying to use the Ceph iSCSI gateway with oVirt. According to my tests with oVirt 4.3.2 * you cannot separate iSCSI discovery auth and target auth * you cannot use an iSCSI gateway that has no discovery auth, but uses CHAP for targets This means I'm forced to use the same credentials for discovery auth and target auth. In Ceph iSCSI gateway I can have multiple targets with use different credentials, but I can define discovery auth only once for the whole gateway (or have no discovery auth). If all of this is correct and I want to use the Ceph iSCSI gateway with oVirt * I have to use discovery auth * the credentials for discovery auth will give every other Ceph iSCSI gateway user access to the oVirt target This is not a desirable situation. Did I understand anything wrong? Are there other ways to solve this? thx matthias

Upgrade 4.1.8 to 4.3.3
by christopher.jorgensen＠gmail.com 01 May '19

01 May '19

I am a little behind in updates but I couldn't find any specific instructions going from 4.1.8 to 4.3.3. From what I read so far, the process for upgrading should be as follows: 4.1.8 --> 4.1.9 https://www.ovirt.org/documentation/upgrade-guide/chap-Upgrading_from_4.1_t… 4.1.9 --> 4.2.0 https://www.ovirt.org/documentation/upgrade-guide/chap-Upgrading_from_4.1_t… 4.2.0 --> 4.2.8 (use instructions above to upgrade to the latest 4.2 before going to 4.3) 4.2.8 --> 4.3.3 Is this correct or should I add / remove upgrade versions?

integration with openstack nove-compute
by ehsan.sabooni＠gmail.com 01 May '19

01 May '19

hello dear all, is it possible to make a compute-nove VM inside oVirt, using which, to be able to create VM instances inside oVirt through openstack horizon? to make it simple, is it possible to have oVirt has the hypervisor for openstack, while having a nova-compute node as a VM inside ovirt? as a hint, the same thing is possible via vsphere vCenter, if we install vCenter driver on the nova-compute node. thank you for your support!

silent install failing in 4.3.3.5-1 due to question on fqdn of host

Anyone happen to know if I can get the following into an answer file for a true silent deployment? It's asking to confirm or change from the fqdn of the host doing the HE install.
