Thanks for the reply. Yes I am aware of that and it seems that's what I will have to do. I have no problem with VDSM managing the file, I just wish it didn't automatically load local storage devices into multipathd. I'm still not clear on the purpose of this automatic management though. From what I can tell there is no difference to hosts/clusters made through this automatic management - i.e. you still have to add storage domains manually in oVirt. Could anyone give any info on the purpose of this auto-management of local storage devices into multipathd in VDSM? Then I will be able to make an informed decision as to the benefit of letting it continue.

Fedora support (was: [ANN] oVirt 4.2.0 Second Beta Release is now available for testing)

We currently have too many problems with fedora to call it even 'Technical Preview', as was done in the past. You can still use the nightly snapshots, and most things work, more-or-less, with some issues having known workarounds. See e.g.: https://bugzilla.redhat.com/showdependencytree.cgi?id=1460625&hide_resolved… And also: http://lists.ovirt.org/pipermail/devel/2017-August/030990.html (not sure that one is still relevant for Fedora 27, didn't check recently). > > On 11/15/2017 9:17 AM, Sandro Bonazzola wrote > > > This release is available now on x86_64 architecture for: > > * Red Hat Enterprise Linux 7.4 or later > > * CentOS Linux (or similar) 7.4 or later > > > This release supports Hypervisor Hosts on x86_64 and ppc64le architectures > for: > > * Red Hat Enterprise Linux 7.4 or later > > * CentOS Linux (or similar) 7.4 or later > > * oVirt Node 4.2 (available for x86_64 only) > > tp://lists.ovirt.org/mailman/listinfo/users > > > > _______________________________________________ > Users mailing list > Users(a)ovirt.org > http://lists.ovirt.org/mailman/listinfo/users > -- Didi

Failed deply of ovirt-engine using ovirt-node-ng-installer-ovirt-4.2-pre-2017120512.iso
by Roberto Nunin 06 Dec '17

06 Dec '17

I'm having trouble to deploy one three host hyperconverged lab using iso-image named above. My test environment is based on HPE BL680cG7 blade servers. These servers has 6 physical 10GB network interfaces (flexNIC), each one with four profiles (ethernet,FCoE,iSCSI,etc). I choose one of these six phys interfaces (enp5s0f0) and assigned it a static IPv4 address, for each node. After node reboot, interface ONBOOT param is still set to no. Changed via iLO interface to yes and restarted network. Fine. After gluster setup, with gdeploy script under Cockpit interface, avoiding errors coming from : /usr/share/gdepply/scripts/blacklist_all_disks.sh, start hosted-engine deploy. With the new version, I'm having an error never seen before: The Engine VM (10.114.60.117) and this host (10.114.60.134/24) will not be in the same IP subnet. Static routing configuration are not supported on automatic VM configuration. Failed to execute stage 'Environment customization': The Engine VM (10.114.60.117) and this host (10.114.60.134/24) will not be in the same IP subnet. Static routing configuration are not supported on automatic VM configuration. Hosted Engine deployment failed. There's no input field for HE subnet mask. Anyway in our class-c ovirt management network these ARE in the same subnet. How to recover from this ? I cannot add /24 CIDR in HE Static IP address field, it isn't allowed. Moreover, VM FQDN is asked two times during the deploy process. It's correct ? Some additional, general questions: NetworkManager: must be disabled deploying HCI solution ? In my attempt, wasn't disabled. There's some document to follow to perform a correct deploy ? Is this one still "valid" ? : https://ovirt.org/blog/2017/04/up-and-running-with-ovirt-4.1-and-gluster-st… Attached hosted-engine-setup log. TIA -- Roberto 110-006-970

New post on oVirt blog: LVM Configuration the Easy Way
by John Marks 05 Dec '17

05 Dec '17

Hello! Just a quick heads up that there is a new post on the oVirt blog: LVM Configuration the Easy Way <https://ovirt.org/blog/2017/12/lvm-configuration-the-easy-way/> In a nutshell: oVirt now features a simple way to prevent a host from scanning and then activating logical volumes that are not required directly by the host, by means of an LVM filter. Read the post <https://ovirt.org/blog/2017/12/lvm-configuration-the-easy-way/>. See you on the oVirt blog! Best, John -- John Marks Technical Writer, oVirt redhat Israel Cell: +972 52 8644 491 -- John Marks Technical Writer, oVirt redhat Israel Cell: +972 52 8644 491

oVirt self-Hosted engine- Hosted Engine failover issue
by Terry hey 05 Dec '17

05 Dec '17

Hello all, i created two hosts in Default cluster. The Hosted Engine was installed in host1. Then i tried to live migrate hosted engine from host1 to host2 and it was OKAY. However, the hosted engine suddenly shut down for a while. Then, when the hosted engine worked again, i found that the hosted engine was located in host1. The problem is that since there is no vms inside these two hosts except hosted engine vm why the hosted engine will suddenly shutdown and auto migrate to host1? Since i am newer for ovirt self hosted engine if you guys want to read some log, would you give me the log path? I very appreciated with your help. Regards, Terry

Success Cases with Hyperconvergence
by Vinícius Ferrão 04 Dec '17

04 Dec '17

Hello, I’m looking for success cases of oVirt (and the downstream part: RHV) specifically on hyperconverged scenarios. I’m trying to convince a customer to ditch its expensive Nutanix quotation in favor of a RHV with Gluster architecture. Looking on redhat page about RHV there’s a lot of cases of RHV on a standard software defined DC but nothing really expressive on hyperconvergence. I’m aware that the product is a bit new and the reference architecture is still on 1.0; but someone have any success case to be a show off? Thanks, V. Sent from my iPhone
