Re: Multiple GPU Passthrough with NVLink (Invalid I/O region)
by Zhengyi Lai 10 Jul '24

10 Jul '24

I noticed this document https://docs.nvidia.com/vgpu/16.0/grid-vgpu-release-notes-generic-linux-kvm… has this to say In pass through mode, all GPUs connected to each other through NVLink must be assigned to the same VM. If a subset of GPUs connected to each other through NVLink is passed through to a VM, unrecoverable error XID 74 occurs when the VM is booted. If a subset of GPUs connected to each other through NVLink is passed through to a VM, unrecoverable error XID 74 occurs when the VM is booted. This error corrupts the NVLink state on the physical GPUs and, as a result, the NVLink bridge between the NVLink and the physical GPUs is not recognized. result, the NVLink bridge between the GPUs is unusable. You may need to passthrough all GPUs in the nvlink to the VM

[URGENT] HCI Hosted_Storage full
by wodel youchi 02 Jul '24

02 Jul '24

Hi, By mistake I have created a disk on the hosted_storage storage domain and it is full and the VM engine has done down. It's an HCI deployment with glusterfs. Is there a way to liberate the used space to be able to start the VM Manager again?

oVirt 4.5.6-1.el9 standalone engine - older VM's on centos 6 or rhel 6 hangs on live migration with ovirt node 5.14.0-388.el9.x86_64
by Sumit Basu 01 Jul '24

01 Jul '24

Hi All, In our new oVirt 4.5.6-1.el9 cluster we find older vm's on el6 (centos/rhel) keeps hanging after live migrations. we find this typically with el6 vm's, our other el'7 and windows vm's do not face this issue. All these VM's were imported from an oVirt 4.3.10.4-1.el7 cluster by importing the storage domain into the new cluster. Initially we installed all the latest ovirt-node-ng-installer-latest-el9 on all our nodes(8 of them) and we found this live migration hang issue, later we installed ovirt-node-ng-installer-4.5.2-2022081013.el9 on the nodes and tested - we found the issue resolved and we could migrate the el6 vm's without any issues at all, later, after doing an upgrade on the nodes we find the issue has come back again. The nodes where there are no live migration issues have kernel 5.14.0-142.el9.x86_64, the nodes with the latest version 5.14.0-388.el9.x86_64 seems to have this issue. Has anybody faced this issue? - any patches needed/available? Thanks

How to re-enroll (or renew) host certificates for a single-host hosted-engine deployment?
by Derek Atkins 28 Jun '24

28 Jun '24

Hi, I've got a single-host hosted-engine deployment that I originally installed with 4.0 and have upgraded over the years to 4.3.10. I and some of my users have upgraded remote-viewer and now I get an error when I try to view the console of my VMs: (remote-viewer:8252): Spice-WARNING **: 11:30:41.806: ../subprojects/spice-common/common/ssl_verify.c:477:openssl_verify: Error in server certificate verification: CA signature digest algorithm too weak (num=68:depth0:/O=<My Org Name>/CN=<Host's Name>) I am 99.99% sure this is because the old certs use SHA1. I reran engine-setup on the engine and it asked me if I wanted to renew the PKI, and I answered yes. This replaced many[1] of the certificates in /etc/pki/ovirt-engine/certs on the engine, but it did not update the Host's certificate. All the documentation I've seen says that to refresh this certificate I need to put the host into maintenance mode and then re-enroll.. However I cannot do that, because this is a single-host system so I cannot put the host in local mode -- there is no place to migrate the VMs (let alone the Engine VM). So.... Is there a command-line way to re-enroll manually and update the host certs? Or some other way to get all the leftover certs renewed? Thanks, -derek [1] Not only did it not update the Host's cert, it did not update any of the vmconsole-proxy certs, nor the certs in /etc/pki/ovirt-vmconsole/, and obviously nothing in /etc/pki/ on the host itself. -- Derek Atkins 617-623-3745 derek(a)ihtfp.com www.ihtfp.com Computer and Internet Security Consultant
