Thanks so much for your reply Robert! I like your set-up alot, that's where I'm going too actually. But now I have only one node, I'm trying to learn very basic setup with just the one for the moment (Because I have it running after years of trying! It will take a few weeks and another motherboard / rebuild before I have the second node, I'll get there soon). I've just learned (I think) that I can't sync new logical networks with the host, because I can't put the only host in maintenance mode...I thought that there might be a way with cli and restarts and all that but lo, there no point, I will have another node in a few weeks or months :) That's okay, I'm trying to work out why I can't access my new test server from WAN. I use split dns with pfsense and haproxy reverse redirects. I can get to the server test pages from LAN via the pfSense dns resolution (LAN) but the reverse redirects are not working from WAN. I don't know what next step to take to debug the problem. The engine is accessible from WAN, so I think it should work for the vm server, which is also on the default ovirt management network and uses all defaults like the hosted engine. I suspect that there is a security setting on the engine, logical network or maybe the server? What should I check next? My singe node, is also in the same condition, which may be instructive to a noob like me...the node I can reach from the LAN but not the WAN. So the engine is a special case. Do I need to create certificates on the vm webserver? I'd like to see if I can set-up a NextCloud server after trying a SuiteCRM server. But I started with fedora 31 server and a very basic lamp stack to limit variables... Thanks in advance. Let me know if I can ever help you with anything! I'm an Architect, but a real one; not IT but bricks and all that :) These are the links: engine.metrodesignoffice.com mdowebserver.metrodesignoffice.com

0virt VMs status down after host reboot
by Eugène Ngontang 31 Jan '20

31 Jan '20

Hi all, I've set up an infrastructure with OVirt, using self-hosted engine. I use some ansible scripts from my Virtualization Host (the physical machine), to bootstrap the hosted engine, and create a set of virtual machines on which I deploy a k8s cluster. The deployment goes well, and everything is OK. Now I'm doing some reboot tests, and when I reboot the physical server, only the hosted-engine vm is up after the reboot, the rest of VMs and thus the k8s cluster are down. Had someone here ever experienced this issue? What can cause it and how to automate the virtual machines startup in RHVE/Ovirt? Thanks.

High level network advice request
by Richard Nilsson 31 Jan '20

31 Jan '20

High level network advice request :) I have a self-hosted engine deployed on a node, Ovirt v. 4.3. I am testing, but I don't understand the big idea of how to set-up Ovirt networking for hosted / engine-managed virtual servers. I would like to host a few virtual servers for things like Next/OwnCloud, SuiteCRM, NethServer or others. For example, I know exactly how set-up a virtual machine with a centos / lamp stack on a fedora host, I can make a network bridge for the vm with fedora cli, then use haproxy (or squid) as a reverse-redirect server to allow WAN access to the vm server using FQDNs. What is a good strategy for Ovirt hosting a webserver? To use the default ovirt management network for the virtual server machines doesn't seem like a best practice? Should I make a new logical network for the virtual servers? Do I need to configure bridges for the machines? It looks like bridges and virtual NICs are automatically configured when I make the network and virtual machines, is that right? Is it the usual or typical practice that one ovirt logical network uses only one network bridge to a one physical NIC? Would all of the kVMs on the logical network share the same / single bridge of the particular network? I'm not sure what the big idea should be, what is a best practice? I wonder, should I bond several physical NICs, then point the bridge, for a new / dedicated logical network for webservers, to the the bonded NICs? There is more than a little new vocabulary for me to onboard for Ovirt / virtual / logical networks...I will greatly appreciate, and I thank you in advance for any top level / best practice advice!

Assign permissions from within the VM portal?
by nicolas＠devels.es 31 Jan '20

31 Jan '20

Hi, We're testing version 4.3.8, we're planning to upgrade to this version in production as currently we're still using 4.1.9. In 4.1.9, users could grant permissions on their created VMs to other users from within the VM portal, however I can't find this option on version 4.3.8. Permissions granted to users so they can create and handle their VMs are VmCreator and DiskProfileUser on the DataCenter. Is there a way to allow users grant permissions on their VMs to other users in the VM portal? Thanks

Hi all, For those of you who are unaware of this, Lars Kurth from the Xen project has passed away [1]. Lars was one of the people who truly practiced open source and worked with the oVirt project on running FOSDEM's Virtualization and IaaS room in the past years. In Lars' memory there will be a special session [2] on Sunday morning, which will be broadcasted live. You're all welcomed to join physically or via the live stream. Thanks, Doron [1] https://lists.xenproject.org/archives/html/xen-announce/2020-01/msg00004.ht… [2] https://fosdem.org/2020/schedule/event/vai_memory_of_lars_kurth/

problem with qemu / dynamic_ownership
by Christoph Köhler 31 Jan '20

31 Jan '20

Hey, is the problem back with qemu/dynamic_ownership? We have one DC with two clusters: one: vdsm-4.30.38 / libvirt-4.5.0-23, two: vdsm-4.30.40 / libvirt-4.5.0-23, LibgfApi enabled, Gluster-Server 6.5.1, Gluster-Client 6.7, opVersion 60000 It went well for a log time but now, with getting vdsm like above, we are getting old problems: °setting disk files to root:root when VM went down °cannot create snapshot etc. Do we have to set dynamic_ownership=0 in qemu.conf? We were testing anything but nothing other worked. Is there any idea? Christoph

Re: [ANN] oVirt 4.3.7 Third Release Candidate is now available for testing
by Strahil 30 Jan '20

30 Jan '20

I got upgraded to RC3 and now cannot power any VM . Constantly getting I/O error, but checking at gluster level - I can dd from each disk or even create a new one. Removing the HighAvailability doesn't help. I guess I should restore the engine from the gluster snapshot and rollback via 'yum history undo last'. Does anyone else have my issues ?
