Contribution opportunity: oVirt website links maintenance
by Sandro Bonazzola 06 May '20

06 May '20

Hi, oVirt website accumulated a good amount of broken links over the years. You can see them listed in this etherpad: https://review.rdoproject.org/etherpad/p/SLEq1-6FwW9aw7344eRr You can help fixing the links by edit text files written in markdown language, it's pretty easy to understand and can be done even by somebody without any development skill. This is a good chance to contribute back to oVirt project, looking forward to review your patches at https://github.com/oVirt/ovirt-site !

by Gianluca Cecchi 06 May '20

06 May '20

Hello, supposing to be already at 4.3.9 level and to have CentOS 7.7 based hosts, are there any blocking factors to update them to 7.8, just released some days ago? Thanks, Gianluca

NFS storage domain forced to use /exports/data ?
by kelley bryan 06 May '20

06 May '20

Hello Should the documentation point out that the /exports/data mount point is hard coded in ovirt-hosted-engine-setup-ansible-create_storage_domain.yaml. I think some Data Centers will want to use a different mount path or Did I miss a prompt or entry in the Deployment screen for Hosted-engine-deployment? Bryan

Unable to import CA certificate list
by Sakari Poussa 06 May '20

06 May '20

Hi, I am using 4.4 beta4 and not able to add new hosts to the datacenter. Also "Enroll Certificate" fails. On nodes, I get the following error message: libvirtd[20399]: Unable to import CA certificate list /etc/pki/vdsm/certs/cacert.pem The root cause is the malformed cert: $ cat /etc/pki/vdsm/certs/cacert.pem -----BEGIN CERTIFICATE-----\nMIID XXX That, is the .pem file is just one long line with \n characters instead of real newlines. If I convert the \n to real newlines libvirtd starts but that is not the end solution since other issues surfaces. The malforming happens when the engine copies (via ansible) the CA cert to the node(s). Any ideas what is going on? Thanks, Sakari

Backup software recommendations
by Colin Coe 06 May '20

06 May '20

Hi all I'm looking for recommendations for backup software. It needs to handle physical and virtual Linux and Windows, RHV and Hyper-V. It doesn't have to be open source and it doesn't have to be free. The main features we need are: - disk to disk backups - inter-site replication with rate limiting - be able to handle Linux thin volumes (think RHGS) - support BMR ans granular file / directory restore - correctly handle Windows VSS - support RHEL point releases as soon as they are released I'm as much after "stay away from" as recommendations. We currently use Arcserve UDP and it is ... well ... sub optimal Thanks in advance CC

VM Portal --> Windows SSO
by Andrey Rusakov 05 May '20

05 May '20

Hi, Resently I configure oVirt, FreeIPA and Windows Guest VM. I would like to SSO to Windows VM thrue VM portal or Rest API (dowloading spice config) or Admin Port ... I don't see any login attemps in log file, errors, or ... I found a lot of docs for SSO setup - it is so simple (Agent, Correct Domain name in login profile ...), But at the end i found that SSO module was deleted from 4.3 agent. Is it true? The major question - Is it working ?

Gluster deployment fails with missing UUID
by Shareef Jalloq 05 May '20

05 May '20

Hi, I'm running the gluster deployment flow and am trying to use a second drive as the gluster volume. It's /dev/sdb on each node and I'm using the JBOD mode. I'm seeing the following gluster ansible task fail and a google search doesn't bring up much. TASK [gluster.infra/roles/backend_setup : Create volume groups] **************** failed: [ovirt-gluster-01.jalloq.co.uk] (item={u'vgname': u'gluster_vg_sdb', u'pvname': u'/dev/sdb'}) => {"ansible_loop_var": "item", "changed": false, "err": " Couldn't find device with uuid Y8FVs8-LP6w-R6CR-Yosh-c40j-17XP-ttP3Np.\n Couldn't find device with uuid tA4lpO-hM9f-S8ci-BdPh-lTve-0Rh1-3Bcsfy.\n Couldn't find device with uuid RG3w6j-yrxn-2iMw-ngd0-HgMS-i5dP-CGjaRk.\n Couldn't find device with uuid lQV02e-TUZE-PXCd-GWEd-eGqe-c2xC-pauHG7.\n Device /dev/sdb excluded by a filter.\n", "item": {"pvname": "/dev/sdb", "vgname": "gluster_vg_sdb"}, "msg": "Creating physical volume '/dev/sdb' failed", "rc": 5}

stty: standard tty: inappropriate ioctl for device
by Charles Kozler 05 May '20

05 May '20

I'd like to share this with the list because its something that I changed for convenience, in .bashrc, but had a not so obvious rippling impact on the ovirt self hosted installer. I could imagine a few others doing this too and I'd rather save future them hours of google time Every install failed no matter what and it was always at the SSO step to revoke token (here: https://github.com/machacekondra/ansible/blob/71547905fab67a876450f95c9ca71…) and then reissue new token but the engine log yielded different information. The SSO failure was a red herring engine.log:2020-05-04 22:09:17,150-04 ERROR [org.ovirt.engine.core.bll.hostdeploy.InstallVdsInternalCommand] (EE-ManagedThreadFactory-engine-Thread-1) [61038b68] Host installation failed for host '672be551-9259-4d2d-823d-07f586b4e0f1', 'node1': Unexpected error during execution: stty: standard input: Inappropriate ioctl for device engine.log:2020-05-04 22:09:17,145-04 ERROR [org.ovirt.engine.core.uutils.ssh.SSHDialog] (EE-ManagedThreadFactory-engine-Thread-1) [61038b68] SSH error running command root@node1:'umask 0077; MYTMP="$(TMPDIR="${OVIRT_TMPDIR}" mktemp -d -t ovirt-XXXXXXXXXX)"; trap "chmod -R u+rwX \"${MYTMP}\" > /dev/null 2>&1; rm -fr \"${MYTMP}\" > /dev/null 2>&1" 0; tar --warning=no-timestamp -C "${MYTMP}" -x && "${MYTMP}"/ovirt-host-deploy DIALOG/dialect=str:machine DIALOG/customization=bool:True': RuntimeException: Unexpected error during execution: stty: standard input: Inappropriate ioctl for device I was on the hunt for this for the better part of 2 days or so, because who else has anything to do during quarantine, wracking my brain and trying everything to figure out what was going on Well, it was my own fault # cat .bashrc | grep -i stty stty erase ^? With this set in the .bashrc of the node I was running the installer via cockpit from, ovirt installer will fail to install This was set for convenience to have backspace work in vim since at some point it stopped working for me Should I file this as a bug? The message generated is more of a warning then a failure but I do not know the internals of ovirt like that. Commands still actually execute fine ovirt-engine(a)192.168.222.84) # ssh 10.0.16.221 "uptime" root(a)10.0.16.221's password: stty: standard input: Inappropriate ioctl for device 22:30:01 up 22:45, 2 users, load average: 0.80, 0.62, 0.80 One thing I think should be called out in the docs, and called out very loud, is that the entire ovirt installer expects a clean 110% machine that is done right after install and provided and IP and hostname. Its not that obvious, but it is now
