OVN network and external access
by Gianluca Cecchi 16 Feb '21

Hello, can I have external access from a VM with vnic configured on OVN network, still maintaining switch type of cluster to Linux Bridge? Or am I forced to use switch type OVS (that seems still in Tech Preview)? Thanks, Gianluca

Re: Ovirt - affinity labels names and virtual machines
by Benny Zlotnik 15 Feb '21

Hi, I suggest sending questions to ovirt-users so others could find answers as well as to allow others who might know better chime in as well As to your question, something like this works for me: vms_service = connection.system_service().vms_service() vm_service = vms_service.vm_service('vm-id') affinity_labels = vm_service.affinity_labels_service().list() for affinity_label in affinity_labels: hosts = connection.follow_link(affinity_label.hosts) for host in hosts: print(connection.follow_link(host).name) (I am not sure where exactly the problem is in your code) On Mon, Feb 15, 2021 at 2:32 PM Lavi Bochnik <lavi.bochnik(a)gmail.com> wrote: > > Hello Benny, > > Not sure if I can email you directly, but you helped me once. > I have some VM's which are labeled with specific affinity. > Via API I would like to get a VM affinity label, in order to later get the hosts defined under that affinity. > I tried many ways as: > vm = vms_service.list(search='<vm_name>')[0] > print(vm.affinity_labels) > > or: > for affinity_label in affinity_labels: > print("%s:" % affinity_label.name) > for vm_link in connection.follow_link(affinity_label.vms): > vm = connection.follow_link(vm_link) > print(" - %s" % vm.name) > > Getting an href error: Error: The URL '/ovirt-engine/api/affinitylabels/0d68b36e-455a-4054-9958-0503d54a18db/vms' isn't compatible with the base URL of the connection > > Href's are looking fine, as: > In [77]: for x in affinity_labels_service.list(): > ...: print(x.href) > > /ovirt-engine/api/affinitylabels/0d68b36e-455a-4054-9958-0503d54a18db > /ovirt-engine/api/affinitylabels/862df742-fdc4-4eb0-933c-027729e2187d > /ovirt-engine/api/affinitylabels/686d96a6-0c9c-4fb7-b453-a79cbd48790b > /ovirt-engine/api/affinitylabels/6d42df24-c4b1-45e7-8029-0ce26b8ed73d > > Or this: > > 1 for affinity_label in affinity_labels: > ----> 2 for h in connection.follow_link(affinity_label.hosts): > 3 print(h) > 4 > 5 > > /usr/local/lib64/python3.6/site-packages/ovirtsdk4/__init__.py in follow_link(self, obj) > 782 raise Error( > 783 "The URL '%s' isn't compatible with the base URL of the " > --> 784 "connection" % href > 785 ) > 786 > > Error: The URL '/ovirt-engine/api/affinitylabels/0d68b36e-455a-4054-9958-0503d54a18db/hosts' isn't compatible with the base URL of the connection > > Not clear what is the right way to get a VM affinity hosts list. > > Thanks, > Lavi

Hello guys, I found a problem when importing VMs from SDs and I filed https://bugzilla.redhat.com/show_bug.cgi?id=1927199 Is there any possible workaround to be able to import them? Everything I tried so far failed miserably... Thanks! -- Miguel Martín Software Maintenance Engineer, Virtualization Red Hat EMEA <https://www.redhat.com/> <https://www.redhat.com/>

Single Node Hyperconverged - Failing Engine Deployment - Network setup?
by jhamiltonactually＠gmail.com 15 Feb '21

15 Feb '21

Ovirt newbie here - installing v 4.4.4 (well, trying to!) Following my post about failing Gluster setup, I can't get the self hosted engine to deploy. I'm installing on my HP DL380p G6. I have 2 disk 170GB Raid 0 for OS and 6 x 330GB disk Raid 5 for Gluster. DNS all set up, but Im realizing I'm missing something here. I have a feeling my problems with Gluster/Engine were caused by incorrect network setup. Seems I'm not the 1st to fall at this hurdle - some people in the community are saying RH have made it's deliberately difficult to get these 'free' set-ups working. It does feel a little like that! Most instructions just say that a 'self hosted, hyperconverged, single node setup requires 2 nics' - and that's about it! That is the 'Networking Pre-requisites'! I've had some help on here and Reddit which eventually made me find a solution some had had to use - editing lvm.conf to make sure my drive (sdb) was being blacklisted correctly. So, with that, Gluster installs, with following DNS settings: The kvm host (ovirt-kvm.whichelo.com) is fixed ip 192.168.0.40 on my 1st nic (Enp0s7) ovirt-engine.whichelo.com - 192.168.0.50 and ovirt-gluster.whichelo.com on 192.168.0.60 - I created I VLAN linked to the nic i want to use for gluster (Enp0s8) and gluster install worked. So now hosted engine won't install,, and pretty sure it's because I don't know how to set the network up properly. I'm seeing virbr0 coming up with different ip's - sometimes 192.168.1.1, sometimes 192.168.222.1. From what I've read, this is something to do with the Engine's network, but I really don't know! Am I still missing something? I can't find any decent instructions on how to do this - how (exactly) to configure the 2 'minimum required' nics? I came to Ovirt after realizing Oracle were dumping their own Virtualization platform in favour of KVM. Couldn't set it up from Oracle so moved to Red Hat - that was a no, and I was at the point where it made most sense to just run an Ovirt node for my KVM. I've got much further with Ovirt, but instructions do not work as easily as they looked! (example 'just click on single node hyperconverged' which didn't work straight off the bat until removing that LVM filter, which took days to find out! The single node HC server is a great match for a home lab/server like mine. I don't want another server, let alone another 2! I'm doing this partly as hobby, but also to update my skills during lockdown. Surely if we can get people using things like this at home, they're more likely to end up using it for work one day? Any help, or just pointing in the right direction, gratefully received! Hopefully I'm a biit clearer here. Happy to provide any logs or anything else.... Thank you!

What will be the impact if we do CIS hardening for Ovirt Engine ? . Systems will be run as we expected ?

Re: ovirt_host_network -> networks: pass list

The following works, however it is looping through the whole routine for each and every VLAN which is a bit sad when the routine itself supports multiple additions in one go, I just can't see how to automatically populate the yml list under the "networks:" parameter. - name: Add Networks to Hosts ovirt_host_network: auth: "{{ ovirt_auth }}" state: present name: "{{ item[0] }}" interface: "bond0" networks: - name: "{{ item[1] }}" wait: true with_nested: - "{{ groups['kvm'] }}" - "{{ groups['net'] }}" Cheers Angus ________________________________ From: Angus Clarke <angus(a)charworth.com> Sent: 14 February 2021 18:07 To: users(a)ovirt.org <users(a)ovirt.org> Subject: ovirt_host_network -> networks: pass list Hello I can see some examples of what I am trying to understand, but I'm still not quite clear, perhaps someone can help? I am trying to lookup a list of network names to pass to the ovirt_host_network, networks parameter.

VM stuck in reboot
by Michael Schmid 14 Feb '21

14 Feb '21

Hi All, I am running on 4.4.4.7-1.el8 I messed up. I was doing some weekend maintenance on VMs and some VMs needed to be stopped and some rebooted and I stopped one, thought I clicked on the next one and clicked shutdown. But... I clicked reboot and shutdown on the same VM, now it is stuck. The Overview in the engine shows the VM "Reboot In Progress" and it has for two weeks at this point, it was a fresh VM so I just created a new one until I had this figured out, but here I am. Clicking "Shutdown" does nothing but generate an error, same with "Power Off" the error I get is --- 2021-02-10 12:04:03,460-05 INFO [org.ovirt.engine.core.bll.StopVmCommand] (EE-ManagedThreadFactory-engine-Thread-244169) [c3ce0a41-3f53-4f3e-993f-0d75f62cc8e6] Running command: StopVmCommand internal: false.
