Getting Redhat Yum mirrors issues on some of my network subnet and not on the others
by Eugène Ngontang 06 Mar '20

06 Mar '20

Hi, This is not really an OVirt matter but I'll try my chance if anyone here has already had this kind of issue or could help I've two bare metal servers in two different network subnets with same release version of RHVH/Ovirt. I use an automated script to deploy VMs on both, and provision a docker repository file there on VMs. The issue I'm facing is when I'm trying to query `container-selinux` package. It works on VMs from one of my bare metal servers, and not from the other. first sever's VM: [root@cpu-node0 ~]# /bin/repoquery --show-duplicates --plugins > --disablerepo '' --enablerepo '' --qf > '%{name}|%{epoch}|%{version}|%{release}|%{arch}|%{repoid}' > container-selinux > container-selinux|2|2.107|1.el7_6|noarch|extras > container-selinux|2|2.107|3.el7|noarch|extras > [root@cpu-node0 ~]# Second server's VM : [root@cpu-node0 ~]# /bin/repoquery --show-duplicates --plugins > --disablerepo '' --enablerepo '' --qf > '%{name}|%{epoch}|%{version}|%{release}|%{arch}|%{repoid}' > container-selinux > Could not match packages: failure: repodata/repomd.xml from > docker-engine: [Errno 256] No more mirrors to try. > https://yum.dockerproject.org/repo/main/centos/7/repodata/repomd.xml: > [Errno 14] HTTPS Error 404 - Not Found > [root@cpu-node0 ~]# The yum repo configuration on both VMs running on each bare metal server: [root@cpu-node0 ~]# ll /etc/yum.repos.d/ > total 44 > -rw-r--r--. 1 root root 1664 5 sept. 13:05 CentOS-Base.repo > -rw-r--r--. 1 root root 1309 5 sept. 13:05 CentOS-CR.repo > -rw-r--r--. 1 root root 649 5 sept. 13:05 CentOS-Debuginfo.repo > -rw-r--r--. 1 root root 314 5 sept. 13:05 CentOS-fasttrack.repo > -rw-r--r--. 1 root root 630 5 sept. 13:05 CentOS-Media.repo > -rw-r--r--. 1 root root 1331 5 sept. 13:05 CentOS-Sources.repo > -rw-r--r--. 1 root root 6639 5 sept. 13:05 CentOS-Vault.repo > -rw-r--r--. 1 root root 369 2 mars 23:31 docker.repo > -rw-r--r--. 1 root root 1050 17 sept. 23:25 epel.repo > -rw-r--r--. 1 root root 1149 17 sept. 23:25 epel-testing.repo > [root@cpu-node0 ~]# docker.repo file content on both VMs : [root@cpu-node0 ~]# cat /etc/yum.repos.d/docker.repo > [docker-ce] > name=Docker-CE Repository > baseurl=https://download.docker.com/linux/centos/7/$basearch/stable > enabled=1 > gpgcheck=1 > keepcache=1 > gpgkey=https://download.docker.com/linux/centos/gpg > > [docker-engine] > name=Docker-Engine Repository > baseurl=https://yum.dockerproject.org/repo/main/centos/7 > enabled=1 > gpgcheck=1 > keepcache=1 > gpgkey=https://yum.dockerproject.org/gpg > [root@cpu-node0 ~]# Repo list on the first VM : [root@cpu-node0 ~]# yum repolist > id du dépôt > nom du dépôt > statut > base/7/x86_64 > CentOS-7 - Base > 10 097 > docker-ce/x86_64 > Docker-CE Repository > 68 > !docker-engine > Docker-Engine Repository > 110 > epel/x86_64 > Extra Packages for Enterprise Linux 7 - x86_64 > 13 199 > extras/7/x86_64 > CentOS-7 - Extras > 323 > updates/7/x86_64 > CentOS-7 - Updates > 1 478 > repolist: 25 275 > [root@cpu-node0 ~]# Yum repo list on the second VM: [root@cpu-node0 ~]# yum repolist > https://yum.dockerproject.org/repo/main/centos/7/repodata/repomd.xml: > [Errno 14] HTTPS Error 404 - Not Found > Essai d'un autre miroir. > To address this issue please refer to the below wiki article > > https://wiki.centos.org/yum-errors > > If above article doesn't help to resolve this issue please use > https://bugs.centos.org/. > > docker-ce/x86_64/primary_db > > | 40 kB 00:00:05 > https://yum.dockerproject.org/repo/main/centos/7/repodata/repomd.xml: > [Errno 14] HTTPS Error 404 - Not Found > Essai d'un autre miroir. > id du dépôt > nom du dépôt > statut > base/7/x86_64 > CentOS-7 - Base > 10 097 > docker-ce/x86_64 > Docker-CE Repository > 68 > docker-engine > Docker-Engine Repository > 0 > epel/x86_64 > Extra Packages for Enterprise Linux 7 - x86_64 > 13 199 > extras/7/x86_64 > CentOS-7 - Extras > 323 > updates/7/x86_64 > CentOS-7 - Updates > 1 478 > repolist: 25 165 > [root@cpu-node0 ~]# I also get the message below when trying to curl the repository URL : > > [root@cpu-node0 ~]#curl > https://yum.dockerproject.org/repo/main/centos/7/repodata/repomd.xml > > <!doctype html> > > <html lang="en"> > > <head></head> > > <body> > > <h1>Notice: Shutting down dockerproject.org APT and YUM repos > 2020-03-31</h1> > > <p>Docker will be shutting down the deprecated APT and YUM > repositories hosted at "dockerproject.org" and "dockerproject.com" on the > 31st of March 2020.</p> > > <p>We noticed that this project is referencing one of these > repositories, and recommend updating to use the "download.docker.com" > repository to prevent disruption.</p> > > <p>More info: > https://www.docker.com/blog/changes-dockerproject-org-apt-yum-repositories/ > </p> > > </body> > > </html> Looks like docker does not want anyone to use this repo anymore. Probably they started issuing the error from today I guess. Of course the two VMs do not have `subscription-manager` package installed, neither subscription attached, they don't need actually in our context, but why is there a mirror issue on one VM and not on the other, whose OS and system configuration is the same on both, except that they are locate in two different networks? Can someone have any idea of why this happens please?

qcow on LVM‽ Why‽
by Thorsten Glaser 06 Mar '20

06 Mar '20

Hi *, I’m a bit frustrated, so please excuse any harshness in this mail. Whose idea was it to place qcow on logical volumes anyway? I was shrinking a hard disc: first the filesystems inside the VM, then the partitions inside the VM, then the LV… then I wanted to convert the LV to a compressed qcow2 file for transport, and it told me that the source is corrupted. Huh? I had already wondered why I was unable to inspect the LV on the host the usual way (kpartx -v -a /dev/VG/LV after finding out, with “virsh --readonly -c qemu:///system domblklist VM_NAME”, which LV is the right one). Turns out that ovirt stores qcow on LVs instead of raw images ☹ Well, vgcfgrestore to my rescue: - vgcfgrestore -l VG_NAME - vgcfgrestore -f /etc/… VG_NAME The image was still marked as corrupted, but exported fine. I could not write it back to the LV as preallocated, which seems to be what ovirt does, because qemu-img doesn’t wish to do that when the target is a special device (not a regular file). Meh. Does ovirt handle raw images on LV, and if so, how can we enable this for new VMs? If not, whyever the hell not? And whose “great” idea was this anyway?

Windows deployment
by eevans＠digitaldatatechs.com 06 Mar '20

06 Mar '20

I have a Windows Deployment server that works with Hyper-V. I am tryng to see if it will bare metal provision to Ovirt. I have the necessary drivers loaded and initially it gets an IP and starts the installation. When it comes to the screen starting setup, I get an IP error. I have included a screenshot. Has anyone see this before? I also considered provisioning from Foreman but I would rather use what I have instead of recreating the entire installation. Any help would be appreciated. Here is a link to the actual error: ftp://ftp.digitaldatatechs.com/pub/Windows%20Provision.jpg

subnets
by eevans＠digitaldatatechs.com 05 Mar '20

05 Mar '20

I have a network in place with several subnets, one for iscsi and one for virtual pbx and VoIP phones. I use the iscsi in Ovirt, but I cannot get Ovirt to recognize and use the physical vlan 3 network for phones. If I add it and the subnet, Ovirt will make give it an IP, but it's an isolated network with no connectivity to the other vm's or the Internet. I have read several topics on this but I can't get it to work properly. Any help would be appreciated. Thanks.

Debian 10 template - cloud init not working
by Sakari Poussa 05 Mar '20

05 Mar '20

Hi, I have tried centos7 & 8, debian 9 and ubuntu 18.04 template based VMs with cloud init (Initial run/use cloud init) and they all work as expected. However, the debian 10 template based VM seems *not* to execute the cloud init at all. It boots but hostname is not set and users / password are not set. You can't log in since there is no users and passwords/keys. Is this a known issue? Or am I missing something? The templates are from ovirt-image-repository storage domain. I have also created newer debian 10.3.0 template via ovirt.image-template ansible role. Results are the same. I am running ovirt 4.4-pre. Thanks, Sakari

When oVirt was deployed in our environment by previous engineers, the DWH was installed as Basic. I would like to change this to Full, to get the daily stats, as this is now empty due to the scale. If it's completely empty, perhaps there is some other problem, not the scale. To further debug this, check that both the engine and dwh access the same database (this should be ok by default, but perhaps you used non-defaults) by checking the credentials they use in their conf files: grep DWH_DB /etc/ovirt-engine/engine.conf.d/*conf grep DWH_DB /etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/*conf You might also check /var/log/ovirt-engine-dwh/ovirt-engine-dwhd.log .
