1. First node that was upgraded now continuously logs this error: VDSM <node name> command Get Host Statistics failed: Internal JSON-RPC error: {'reason': "'str' object has no attribute 'decode'"} 2. During import of two virtual machines from VMware (has done multible before upgrade) the import seems to never finish - currently running on day 2-3... any clues how to fix this? Events VDSM <node name> command Get Host Statistics failed: Internal JSON-RPC error: {'reason': "'str' object has no attribute 'decode'"} running for 2 days every 20 seconds. Please suggest

Hi Team In my one of three node Hyperconverged (gluster + ovirt) setup, one of the storage domain went offline from Datacenter due to 100% storage space utilization, but luckily it is still online in Gluster. how should I properly delete some of the vdisks in that offline stoarge domain from Gluster and bring back to online?

Fresh install on CentOS Stream 8. After installing ovirt-hosted-engine-setup, I encounter the following dependency errors when trying to run dnf upgrade: Error: Problem 1: package rsyslog-openssl-8.2102.0-5.el8.x86_64 requires rsyslog = 8.2102.0-5.el8, but none of the providers can be installed - cannot install both rsyslog-8.2102.0-6.el8.x86_64 and rsyslog-8.2102.0-5.el8.x86_64 - cannot install the best update candidate for package rsyslog-openssl-8.2102.0-5.el8.x86_64 - cannot install the best update candidate for package rsyslog-8.2102.0-5.el8.x86_64 Problem 2: package ovirt-host-dependencies-4.4.9-2.el8.x86_64 requires rsyslog-openssl, but none of the providers can be installed - package rsyslog-openssl-8.2102.0-5.el8.x86_64 requires rsyslog = 8.2102.0-5.el8, but none of the providers can be installed - cannot install both rsyslog-8.2102.0-6.el8.x86_64 and rsyslog-8.2102.0-5.el8.x86_64 - package rsyslog-elasticsearch-8.2102.0-6.el8.x86_64 requires rsyslog = 8.2102.0-6.el8, but none of the providers can be installed - cannot install the best update candidate for package rsyslog-elasticsearch-8.2102.0-5.el8.x86_64 - cannot install the best update candidate for package ovirt-host-dependencies-4.4.9-2.el8.x86_64 Problem 3: problem with installed package rsyslog-openssl-8.2102.0-5.el8.x86_64 - package rsyslog-openssl-8.2102.0-5.el8.x86_64 requires rsyslog = 8.2102.0-5.el8, but none of the providers can be installed - cannot install both rsyslog-8.2102.0-6.el8.x86_64 and rsyslog-8.2102.0-5.el8.x86_64 - package rsyslog-mmjsonparse-8.2102.0-6.el8.x86_64 requires rsyslog = 8.2102.0-6.el8, but none of the providers can be installed - cannot install the best update candidate for package rsyslog-mmjsonparse-8.2102.0-5.el8.x86_64 Problem 4: package ovirt-host-4.4.9-2.el8.x86_64 requires ovirt-host-dependencies = 4.4.9-2.el8, but none of the providers can be installed - package ovirt-host-dependencies-4.4.9-2.el8.x86_64 requires rsyslog-openssl, but none of the providers can be installed - package rsyslog-openssl-8.2102.0-5.el8.x86_64 requires rsyslog = 8.2102.0-5.el8, but none of the providers can be installed - cannot install both rsyslog-8.2102.0-6.el8.x86_64 and rsyslog-8.2102.0-5.el8.x86_64 - package rsyslog-mmnormalize-8.2102.0-6.el8.x86_64 requires rsyslog = 8.2102.0-6.el8, but none of the providers can be installed - cannot install the best update candidate for package rsyslog-mmnormalize-8.2102.0-5.el8.x86_64 - cannot install the best update candidate for package ovirt-host-4.4.9-2.el8.x86_64 (try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages) Running dnf distro-sync --nobest allows it to proceed, which causes some ovirt packages to be upgraded. Running hosted-engine --deploy and installing with nfs storage, everything goes good up until stage 5, at which point vdsm pegs a core at 100% for some minutes, until the task inevitably fails. hosted-engine --vm-status reports EngineStarting forever. No memory is consumed to indicate that the VM even started. The VM never even tries to get a DHCP lease from my router. All indicators point the vm just not starting, for some reason. Zero useful information available on Google. Zero useful information available in the documentation. Zero useful information available in the logs. No clear cause as to why the hosted engine refuses to start. The NFS share has correct permissions, and can be mounted. The NFS share is on the same host the engine is being installed to, in the same subnet/vlan and, even through the same network adapter. The shared storage works fine for copying the local hosted engine to the shared storage during the setup process and I can see the files have been created.

on-demand machine creation for VDI project
by Luca Contessa 06 Dec '21

06 Dec '21

Hi List, I've made an oVirt node installation (oVirt ver. 4.4.9) for a VDI project and I'd like to ask if it is possible to create an empty pool with a maximum number of machine and as the machine are required by the end user (so when the users use the think client to request the provisioning of a machine of the pool in question) the pool will dynamically create the machine and link it to the end user. To specify once more the pool will be create with no machine in it, only a maximum limit on the number of machines, and as the user start connecting to the pool the VM will be created, started and provisioned to the user requesting them. Then when the user stop using the machine they would like the system to save the datas and stop the machine and from that point on when the user will connect the virtual machine connected to their account on the AD system should start. Do you know if this is possibile? Thanks a lot to everybody, Luca

How to turn off the state of tlbflush for Windows vm
by Hean-Seng Tan 05 Dec '21

05 Dec '21

We encounter random Windows BSOD (blue screen of death) issues for vm's in environment running oVirt Engine 4.4.4. Upgrading the environment to 4.4.8 does not fix the issue. There is a suggestion from https://bugzilla.redhat.com/show_bug.cgi?id=1868572 to turn off the state of tlbflush under hyperv section for the Windows vm. Does anyone know how to achieve that? Currently, vm description returned from api call includes the following section that has tlbflush state: <features> <acpi/> <hyperv> <relaxed state='on'/> <vapic state='on'/> <spinlocks state='on' retries='8191'/> <vpindex state='on'/> <runtime state='on'/> <synic state='on'/> <stimer state='on'/> <reset state='on'/> <frequencies state='on'/> <reenlightenment state='on'/> <tlbflush state='on'/> </hyperv> </features>
