Add nodes to single node gluster hyperconverged

by Mathieu Valois

Hi everyone, is it possible to add nodes to a single node gluster hyperconverged setup? I have 3 nodes, one has been reinstalled with single node HE and VMs migrated on it. How can I add the two other nodes to this setup? Thank you, M.

oVirt and the future

by thilburn＠generalpacific.com

Hi all, I'm looking for some information about the future of oVirt. With CentOS going away have they talked about what they will be doing or moving to? I'd like to see Ubuntu support.

Importing VM from Xen Server 7.1

by francesco＠shellrent.com

Hi all, resuming the "dead" thread "Importing VM from Xen Server 6.5" (https://lists.ovirt.org/pipermail/users/2016-August/075213.html) I'm trying to import via GUI a VM from Xen Server 7.1 in a host Centos 8.4, oVirt 4.4. Created the SSH key for vdsm user, added the IP in the host target firewall, an ssh connection works, installed netcat on the target host, but like the original thread, when i execute the "load" command for getting the VMS list, I get the following error in the host and in the engine: Aug 27 12:04:43 centos8-4.host vdsm[78126]: ERROR error connecting to hypervisor#012Traceback (most recent call last):#012 File "/usr/lib/python3.6/site-packages/vdsm/v2v.py", line 193, in get_external_vm_names#012 passwd=password)#012 File "/usr/lib/python3.6/site-packages/vdsm/common/libvirtconnection.py", line 107, in open_connection#012 return function.retry(libvirtOpen, timeout=10, sleep=0.2)#012 File "/usr/lib/python3.6/site-packages/vdsm/common/function.py", line 58, in retry#012 return func()#012 File "/usr/lib64/python3.6/site-packages/libvirt.py", line 148, in openAuth#012 raise libvirtError('virConnectOpenAuth() failed')#012libvirt.libvirtError: End of file while reading data: Ncat: No such file or directory.: Input/output error Trying the command virsh -c xen+ssh://root@xen7.target the same error: error: failed to connect to the hypervisor error: End of file while reading data: Ncat: No such file or directory.: Input/output error Any ideas?

bond (802.3ad) interface

by Jorge Visentini

Hey all! I'm trying to set up a bond (802.3ad) and then add the host to the cluster, but it crashes minutes after being UP. I have other hosts with bond and they work perfectly, but this one has this problem. I noticed that when I create the bond, the MTU doesn't appear on the bond interface... but that was the only difference. I've reviewed the configuration on the switches several times and I don't find the problem. Does anyone have a tip? *This bond works:* [image: image.png] *This bond does not work:* [image: image.png] -- Att, Jorge Visentini +55 55 98432-9868

How to re-import a VM with an invalid timezone?

by hibbsncc1701＠gmail.com

I've just finished my upgrade to oVirt 4.4.8.4, but I've got one previously working VM that I cannot reimport. (I did a fresh install instead of restoring an engine backup.) It's a Windows VM, and every attempt I make to import it causes the following error: Cannot import VM. Invalid time zone for given OS type. Attribute: vm.vmStatic The interface doesn't give me the option to change the timezone before import. The most that I can get from the logs on either the engine host or SPM host is this: 2021-08-26 17:38:30,793-04 WARN [org.ovirt.engine.core.bll.exportimport.ImportVmFromConfigurationCommand] (default task-35) [96d9f0ea-99be-477a-b1d1-3781ffbac041] Validation of action 'ImportVmFromConfiguration' failed for user admin@internal-authz. Reasons: VAR__ACTION__IMPORT,VAR__TYPE__VM,ACTION_TYPE_FAILED_INVALID_TIMEZONE,$groups [Ljava.lang.Class;@b263017,$message ACTION_TYPE_FAILED_INVALID_TIMEZONE,$payload [Ljava.lang.Class;@3b789cbf,ACTION_TYPE_FAILED_ATTRIBUTE_PATH,$path vm.vmStatic,$validatedValue org.ovirt.engine.core.common.businessentities.VmStatic@9f994c52 Does anyone know how to get a VM imported in this case? Thanks.

about the hugepage setting of the KVM server

by Tommy Sway

Hi: I am running virtual machines on the KVM servers of oVirt env. The virtual machine is running database, which needs to set the memory huge page on the OPERATING system of the virtual machine. If I need to set the huge page on the VIRTUAL machine, do I also need to set huge page on the KVM physical machine? Or just on the virtual machine? What best practices do you recommend? Thank you very much!

Fwd: oVirt 4.4.8 is now generally available

by Sandro Bonazzola

---------- Forwarded message ---------- From: *Sandro Bonazzola* <sbonazzo(a)redhat.com> Date: Thursday, August 19, 2021 Subject: oVirt 4.4.8 is now generally available To: oVirt Users <users(a)ovirt.org> oVirt 4.4.8 is now generally available The oVirt project is excited to announce the general availability of oVirt 4.4.8 , as of August 19th, 2021. This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics, as compared to oVirt 4.3. Important notes before you install / upgrade Please note that oVirt 4.4 only supports clusters and data centers with compatibility version 4.2 and above. If clusters or data centers are running with an older compatibility version, you need to upgrade them to at least 4.2 (4.3 is recommended). Please note that in RHEL 8 / CentOS 8 several devices that worked on EL7 are no longer supported. For example, the megaraid_sas driver is removed. If you use Enterprise Linux 8 hosts you can try to provide the necessary drivers for the deprecated hardware using the DUD method (See the users’ mailing list thread on this at https://lists.ovirt.org/archives/list/users@ovirt.org/ thread/NDSVUZSESOXEFJNPHOXUH4HOOWRIRSB4/ ) Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. What’s new in oVirt 4.4.8 Release? This update is the eighth in a series of stabilization updates to the 4.4 series. This release is available now on x86_64 architecture for: - Red Hat Enterprise Linux 8.4 - CentOS Linux (or similar) 8.4 - CentOS Stream 8 This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: -
