Can't seem to find this, maybe I'm old school but in 4.4 how do I upload ISO's I want to boot as CD's on my virtual machine?

oVirt 4.4.1 First Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.1 First Release Candidate for testing, as of May 25th, 2020. This update is the first in a series of stabilization updates to the 4.4 series. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Some of the features included in oVirt 4.4.1 Release Candidate require content that will be available in CentOS Linux 8.2 but can’t be tested on RHEL 8.2 beta yet due to some incompatibility in openvswitch package shipped in CentOS Virt SIG which requires to rebuild openvswitch on top of CentOS 8.2. Installation instructions For the engine: either use appliance or: - Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps postgresql:12 - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… ; select minimal installation - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - Attach the host to engine and let it be deployed. This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.1 or newer * CentOS Linux (or similar) 8.1 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.1 or newer * CentOS Linux (or similar) 8.1 or newer * oVirt Node 4.4 based on CentOS Linux 8.1 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed. If you manage more than one oVirt instance, OKD or RDO we also recommend to try ManageIQ <http://manageiq.org/>. In such a case, please be sure to take the qc2 image and not the ova image. Notes: - oVirt Appliance is already available for CentOS Linux 8 - oVirt Node NG is already available for CentOS Linux 8 Additional Resources: * Read more about the oVirt 4.4.1 release highlights: http://www.ovirt.org/release/4.4.1/ * Get more oVirt project updates on Twitter: https://twitter.com/ovirt * Check out the latest project news on the oVirt blog: http://www.ovirt.org/blog/ [1] http://www.ovirt.org/release/4.4.1/ [2] http://resources.ovirt.org/pub/ovirt-4.4-pre/iso/ -- Lev Veyde Senior Software Engineer, RHCE | RHCVA | MCITP Red Hat Israel <https://www.redhat.com> lev(a)redhat.com | lveyde(a)redhat.com <https://red.ht/sig> TRIED.

searching in manager
by Jiří Sléžka 25 May '20

25 May '20

Hi, oVirt 4.3.9.4-1.el7 I am trying to search a vms which has storage domain other than RHEV-SSDStorage so I entered this search string in Manager in Compute / Virtual Machines search form. Storage != "RHEV-SSDStorage" but it looks like all vms are listed. When I try... Storage = "RHEV-SSDStorage" ...it works like expected and only right vms are listed. Also combinations seems does not work. Storage = "RHEV-SlowStorage" or Storage = "RHEV-MidStorage" ...returns 0 rows. Should it work? Cheers, Jiri

how to save stateless disk
by Jiří Sléžka 25 May '20

25 May '20

Hi, I have one vm configured as stateless (useful for example for testing ansible deploying). But now I am in the middle of work and we have planned power outage. If I power down this wm now I will lost my work. It looks like I am unable to create snapshot if vm is in stateless state. Is there any trick how to not loose my stateless state? Is it RFE worth problem? Cheers, Jiri

How to upgrade my cluster to 4.4 without pain (it will be useful not only to me)
by Patrick Lomakin 25 May '20

25 May '20

We have four hosts with self-hosted engines. Installed version of the engine 4.3.9. I have the power reserve to migrate all virtual machines to three hosts and spend on construction on the remaining host. I really want someone to help me make a plan to upgrade and upgrade to version 4.4 without pain. I will describe the configuration in more detail: 4 hosts where ovirt node 4.3.9 was deployed, and then one of them has an ovirt engine with a control panel deployed. In the process the storage was added and everything works fine. In the ovirt settings, when adding a host, I deployed a backup engine (gray crown icon). Backup engine is available on each host and was specially tested when one of the hosts was turned off. "Now as I think it will update and there will be questions immediately." 1. My first step is to remove a free host from the control panel and deploy ovirt node (4.4) on it 2. Next, the question arises: since I have to restore the new engine from backup 4.3.9, will it not show a version incompatibility? 3. If I need to restore the backup, then logically I have to disable all my engines and then restore? 4. When I restore the engine, will my hosts and virtual machines go nowhere? Will hosts with old version 4.3.9 be available? Please do not criticize me and understand correctly - there are over 100 virtual machines with important data. A rough plan could help me minimize serious errors. In addition, I could share my upgrade experience with the real configuration, which could help both developers and administrators. Regards!

Issues encountered performing HE install on 4.3
by Alan G 24 May '20

24 May '20

Hi, I hit a few issues while performing a recent HE install of 4.3. While I managed to find solutions/workarounds to all the problems I thought I might share them here * As defined in the Ansible defaults the temp dir for building the local HE VM is /var/tmp. I was 80M short of the required space and there did not appear to be a (supported) way to specify a different location. I ended up having to do a bind mount of /var/tmp to get me through the install. Would be nice to be able to specify a custom location. * Permissive umask required. Our CIS CentOS 7 build requires that default umask is 027. This breaks the installer as it creates the VM image under /var/tmp as root and cannot then access it as qemu user. As the temp files are cleaned up on failure it took me a while to track this one down. My solution was to temporarily set the umask to 022 for the session while running the installer. It would be nice if the installer either handled this by doing a chmod/chown as required, or at least doing a umask pre-check and failing with a meaningful error. * SSH root login required on host. Again for CIS we have "PermitRoologin no" configured in sshd. This means the add host task fails on the Engine, but instead of a hard failure we get a timeout on the installer. Which left me chasing some imagined routing/bridging/DNS issue. Eventually I realised I could get to the engine logs and found the issue but took several hours. Would be nice if the installer could either support a sudo option or at least perform a root login pre-check and fail with a meaningful error. Thanks, Alan
