OVirt hosted engine setup dnf config
by Raphael Höser 19 Aug '20

19 Aug '20

Hi all, I'm currently installing OVirt 4.4 on CentOS 8 in an hosted engine setup and it fails during ovirt-hosted-engine-setup. Because of our corporate proxy, some changes to the dnf.conf is needed (namely proxy_auth_method=basic) and the config is working fine when running dnf commands the normal way. Proxy configuration is provided via http_proxy, https_proxy and ftp_proxy env vars. The setup fails during a DNF call with status code 407 (proxy auth required). Is there another way to provide that config or any other way to resolve this? My googling didn't help me yet. On the same machine I had a running OVirt 4.3 on CentOS 7 running as a test and now wanted to upgrade (after a complete wipe). Thanks for your help, Raphael content of /etc/dnf/dnf.conf: [main] gpgcheck=1 installonly_limit=3 clean_requirements_on_remove=True best=True skip_if_unavailable=False proxy_auth_method=basic timeout=120 minrate=90 Log of ovirt-hosted-engine-setup: [ INFO ] Stage: Initializing [ INFO ] Stage: Environment setup During customization use CTRL-D to abort.

Re: Help remove snapshot

Hi Magnus, You can find the VM's snapshot by sending a REST API request http://localhost:8080/ovirt-engine/api/vms/<vm-id>/snapshots/ You can also find the VM's snapshots (and view their parameters) by using SQL: select * from snapshots where vm_id = '<vm-id>'; You can also delete the relevant snapshot by specifying the snapshot's description: *delete from snapshots where description = '.....';* *Regards,* *Shani Leviim* On Tue, Aug 18, 2020 at 7:50 PM Magnus Isaksson <magnus(a)vmar.se> wrote: > Hi Shani > > Thanks for the help. > > What i can see it does not display any illegal statuses. > > I am a bit unsure how to delete it from the DB, how do i find the > snapshot_id? > > Cheers > Magnus > > ------------------------------ > *From:* Shani Leviim <sleviim(a)redhat.com> > *Sent:* 17 August 2020 13:45 > *To:* Magnus Isaksson <magnus(a)vmar.se> > *Cc:* users <users(a)ovirt.org> > *Subject:* Re: [ovirt-users] Help remove snapshot > > Hi Magnus, > Sounds like you triggered this one > https://bugzilla.redhat.com/show_bug.cgi?id=1555116. > The error message you've got was meant to avoid removing a snapshot from a > broken chain. > > On the Active VM snapshot -> Disks, is there any disk with Illegal status? > > Deleting the whole snapshot can be done from the DB: > *delete from snapshots where snapshot_id = '.....';* > > Although it's recommended to understand the root cause for that one. > > Can you please share your engine.log? > > > *Regards, * > > *Shani Leviim * > > > On Mon, Aug 17, 2020 at 1:37 PM Magnus Isaksson <magnus(a)vmar.se> wrote: > > Hi! > > I would need some help removing a snapshot that looks like this. > How do i remove it manually or fix snapshot definition? > ----------------- > Error while executing action: > > TUN_SALDC01: > > - The requested snapshot has an invalid parent, either fix the > snapshot definition or remove it manually to complete the process. > > ----------------- > And when i look at the disk on tha tnapshot it show as this: > > > And general info: > > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org > Privacy Statement: https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct: > https://www.ovirt.org/community/about/community-guidelines/ > List Archives: > https://lists.ovirt.org/archives/list/users@ovirt.org/message/5QEBPZPUHDGS5… > >

HA Storage options
by David White 19 Aug '20

19 Aug '20

Hi, I started an email thread a couple months ago, and felt like I got some great feedback and suggestions on how to best setup an oVirt cluster. Thanks for your responses thus far.My goal is to take a total of 3-4 servers that I can use for both the storage and the virtualization, and I want both to be highly available. You guys told me about oVirt Hyperconverged with Gluster, and that seemed like a great option. However, I'm concerned that this may not actually be the best approach. I've spoken with multiple people at Red Hat who I have a relationship with (outside of the context of the project I'm working on here), and all of them have indicated to me that Gluster is being deprecated, and that most of the engineering focus these days is on Ceph. I was also told by a Solutions Architect who has extensive experience with RHV that the hyperconverged clusters he used to build would always give him problems. Does oVirt support DRBD or Ceph storage? From what I can find, I think that the answer to both of those is, sadly, no. So now I'm thinking about switching gears, and going with iSCSI instead. But I'm still trying to think about the best way to replicate the storage, and possibly use multipathing so that it will be HA for the VMs that rely on it. Has anyone else experienced problems with the Gluster hyperconverged solution? Am I overthinking this whole thing, and am I being too paranoid? Is it possible to setup some sort of software-RAID with multiple iSCSI targets? As an aside, I now have a machine that I was planning to begin doing some testing and practicing with. Previous to my conversations with the folks at Red Hat, I was planning on doing some initial testing and config with this server before purchasing another 2-3 servers to build the hyperconverged cluster.

Cannot access Engine VM
by Steven Bach 18 Aug '20

18 Aug '20

Hello All, I installed Ovirt node 4.4.1.5 from the ovirt ISO, IP 192.168.1.53/24 I setup the self hosted engine by logging into the web interface, configured it for 192.168.1.55/24 IP on the default generated bridge interface and setup a FQDN that is resolvable via DNS. Setup NFS storage, and all seems good. The Engine VM is running, but I cannot access it at all outside the node. SSH'd in the node I can ping the engine, anything else on that same subnet cannot SSH or even ping it (Again, DNS is resolving correctly to the IP Address). I am able to SSH into the engine from the node. While SSH'd into the Engine from the node, I can only ping the Node and nothing beyond that, not able to install ovirt repo, nothing. Any ideas are greatly appreciated, thank you, -- Steven Bach sbach(a)bachnetworks.com

Uploading images from the UI was available in ovirt 4.4.0, but is fully functional since ovirt 4.4.1. We know about hone issue - if you replaced apache certificates with 3rd party certificates, uploading via ovirt-imageio service on engine host (as a proxy) will not work: https://bugzilla.redhat.com/1866745 https://bugzilla.redhat.com/1862107 If you are using engine built certificates, upload and download should work. We may have more info about the failure in engine log. Please share the log showing the time when you tried to upload an image. Nir

How to diable dhcp in ovirt network
by Adam Xu 17 Aug '20

17 Aug '20

Hi everyone Recently, when I install okd on ovirt. The installation process was failed because the vm automatically acquired an IP address from DHCP before the installer assigned it. Our DHCP is enabled by a layer 3 switch, I tried to diable dhcp using network filter. but there is no entry related to blocking the DHCP feature. Is there any way for ovirt to disable DHCP? -- Adam Xu
