Moving Hosted Engine Storage
by Dan Poltawski 16 Jul '19

16 Jul '19

Hello, I've read various posts[1] on this list, but I must confess that I am still not entirely clear on the process for moving a hosted engine to a new storage domain (in my case I want to move from an existing NFS server to a new iSCSI target). Some of what i've read make me slightly concerned it's a risky operation and in my situation I am just prototyping and retaining the existing engine will be saving some time rather than mission critical. Is anyone able to outline the steps to me? thanks, Dan [1] https://lists.ovirt.org/pipermail/users/2017-June/082466.html ________________________________ The Networking People (TNP) Limited.

Re: Update 4.2.8 --> 4.3.5

I'm addding gluster-users as I'm not sure if you can go gluster v3 -> v6 directly. Theoretically speaking , there should be no problem - but I don't know if you will observe any issues. @Gluster-users, Can someone share their thoughts about v3 to v6 migration ?

VM status codes
by Mitja Mihelič 15 Jul '19

15 Jul '19

Hi! We are graphing certain parameters we collect from the engine database. We use following query to get the count of running VMs: select count(*),cluster.name as cluster from vms, cluster where vms.cluster_id = cluster.cluster_id and vms.status = 1 group by cluster; It would help extremely if we knew what the numeric VM status codes mean. For example, I know that "status = 1" means the VM is running. The ones we can cause through the web interface are easy enough to figure out. But there are error states, that cannot be produced by standard use. For instance, when the event log says "VM foobar has been paused due to storage I/O problem." the following states get set in the DB (Query used: select * from vm_dynamic where vm_guid =(select vm_guid from vm_static where vm_name = 'foobar';): status | 4 exit_status | 0 pause_status | 2 guest_agent_status | 0 What do they mean? If you could point me to a table somewhere with the state descriptions it would be extremely helpful. Kind regards, Mitja Mihelič

SSH Authorized_keys
by Vrgotic, Marko 15 Jul '19

15 Jul '19

Dear oVIrt, Would it be possible to utilize SSH Pub key from User config [cid:image001.png@01D53B2B.0E387070] In such a way that it is offered or autoloaded into Cloud-init SSH Authorized keys field when exists? This would bring one less action required before VM can be created. Kindly awaiting your reply. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic

Re: ovirt-engine-appliance ova

Exactly. Ovirt (and RHV respectively) can be installed as: 1. VM in an oVirt Cluster 2. Separate machine(s) In point 2 , the Virt admin should take care about the high availability of the engine. So, you can install CentOS7 and then deploy the engine's software ontop of it. Extracting the OVA will not provide you with fully working engine, as the deployment scripts on the hosts will not inject the necessary data on remote system.

Add Instance_type option for VM Portal
by Vrgotic, Marko 15 Jul '19

15 Jul '19

Dear oVIrt, We are relying on Templates more and more, which is great. Images/templates built using “official” cloud images usually have 1CPU and 1GB of RAM. Using this feature via Administration portal is super, since we can attach Instance_type to template to provide sufficient CPU and RAM, regardless of via UI or using Ansible. Would it be possible to consider adding Instance_Type option to Create New VM options in VM Portal? Haven’t tested yet, but is Instance_type supported via ovirt_vm ansible module, in case of EndUser privileges? Kindly awaiting your reply. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic Sr. System Engineer @ System Administration m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> tel. +31 (0)35 677 4131 ActiveVideo BV Mediacentrum 3741 Joop van den Endeplein 1 1217 WJ Hilversum

iptables with 4.3+?
by Jordan Conway 15 Jul '19

15 Jul '19

Hello, I'm working on migrating an existing ovirt setup to a new hosted-engine setup and I've been seeing messages about iptables support being deprecated and slated to be removed. Can I continue using iptables to manage the firewalls on my ovirt hosts if I don't care about allowing ovirt to configure the firewalls? We manage all of our machines with puppet and iptables is deeply integrated into this. It would be non-trivial to migrate to firewalld support. As it stands I already manage the firewall rules for our ovirt hosts with puppet and iptables and have always ignored the "Automatically Configure Firewall" option when adding new hosts. Will this continue to work? Also with hosted engine, I had to cowboy enable firewalld to get the engine installed, but now that I've got a cluster up and running with hosted engine enabled on several hosts, can I just switch back from firewalld to iptables assuming I've got all the correct ports open? Thank you, Jordan Conway

Based on my experience - the OVA contains the xml and the actual disk of the hosted engine. Then the deployment starts locally the VM and populates the necessary data in it Once it's over , the deployment shuts down and copies the disk of that local VM, undefines it and then ovirt's ha agents are being configured - so they can mount the shared storage and power up the VM (special tar /OVMF/ file on shared storage has the agent configuration file). So , in the ova there should be a template VM + the xml config (cpus, ram, devices, etc) . I would be surprised if there is something else in it.

hosted engine installation on iscsi multipath/mpath device fails
by Michael Frank 14 Jul '19

14 Jul '19

Dear all, since several days i try to install the hosted engine initially to an iscsi multipath device without success. Some information on the environment: - Ovirt Version 4.3.3 - using two 10gbe interfaces as single lacp - bond for the ovirtmgmt interface - using two 10gbe storage interfaces on each hypervisor for iscsi storage -- each storage interface is configured without any lacp bonding or 802.1q tagging, etc (on the switches the vlan is configured; port based vlan) -- each storage interface lives in a serarate vlan were also the iscsi target is available, the iscsi target has 4x10ge interfaces -- so; each storage interface is connected to a iscsi target through a different vlan The documentation here is for me unclear: https://ovirt.org/documentation/self-hosted/chap-Deploying_Self-Hosted_Engi… <https://ovirt.org/documentation/self-hosted/chap-Deploying_Self-Hosted_Engi…> >Note: To specify more than one iSCSI target, you must enable multipathing before deploying the self-hosted engine. There is also a Multipath >Helper tool that generates a script to install and configure multipath with different options. This indicates for me that it should be possbile to install the HE directly on the /dev/mapper/mpath device which is availibale when I have prepared the host accordingly before installing the HE (log in to multiple iscsi targets, create proper multipath,conf, etc) - right ? I login to the two iscsi targets and get in sum 8 pathes, 4 from each interface and iscsi target. I have then the mpath device on the hypervisor available and i can mount the mpath device and put (test) data on it. In the cockpit interface the mount can also be activated and is recognized correctly. multipathd -ll and lsblk looks good. Everything seems to be fine. But when I run the "hosted-engine" --deploy, the last option while running the assistant is to enter the iscsi data. So, basically i just want to define my mpath device - when entering the data for one of my iscsi target I can see the 4 pathes of the single target, and when i choose the path where the "lun" is finally available it fails. I think in general this option is not that what i want to have here for using the multipath device. I' m lost - what is the usual way to install the HE on a mutlipath device ? Do I have to change the configuration of the storage interfaces or the iscsi network design? - Are bond interfaces for these iscsi connections mandatory ? Did I missed something obvious ? Can I put in my multipath data into the answerfile somehow to get rid of the last step of the assistant ? Is it not possible in general ?? : https://bugzilla.redhat.com/show_bug.cgi?id=1193961 <https://bugzilla.redhat.com/show_bug.cgi?id=1193961> Sorry in advance for the long mail .... 1!^^ br, michael
