by Krzysztof Wajda 08 Jul '18

08 Jul '18

Hi, can anyone explain differences between Ovirt and RHEV in version 4.1 ? I know that RHEV has diffrent product life-cycle, and there are some diffrences in installation process. Do you know if there are any additional featuers in Ovirt or RHEV ? Do you know any oifficial statements from RH about differences ? From my experience there is not too much diffrences, but I need to prepere such a comaprison for bussines so I would like to get an info from relaiable source. Chris

Ovirt/ RHV Disaster Recovery Designing
by samee095＠gmail.com 07 Jul '18

07 Jul '18

Hi I've looking for some ideas about designing disaster recovery planning with ovirt 4.2. Since 4.2 we have options to have intergration with disaster recovery site also. I went through some videos at internet and want to share if those are correct or not. Thus you can help me regarding what other things I should be having ideas during planning and designing more about this. 1. We've to keep both sites on and already created datacenter, cluster and one site with storage domain attached and other site with no storage domain. 2. We've to keep latency of 10ms at maximum between both sites. 3. Have to configure virtual machines with affinity group. 4. The VM's which are configured as high-available vm, will be migrated first. 5. There's an Ansible script while have to run to fail over and fail back. Now, please could you help me out regarding this. 1. Where can I find this ansible script? Is this https://github.com/oVirt/ovirt-ansible-disaster-recovery.git? 2. Can this script run at rhv also ? or just for ovirt? Or what other changes I have to make for rhv to have this functionalities? 3. How ovirt/rhv works with the OVN compared to NSX? Is there's any challenges ? 4. Can you share me some high and low level diagram related to rhv disaster planning? 5. How the storage migrates on backend ? During the script ? 6. Where do I run this script? During fail over at primary site and during fail back at secondary site? 7. Basically since only the storage migrates and all other components are on already so basically backend it's only dealing with storage migration according to defined policies ? Please could you help me out with some designing and ideas what're the best architecture during planning on disaster recovery at RHV. Thank you.

Is your engine functioning at all? I'm not sure if you're saying your entire engine doesn't work, or just host deploy doesn't work. What version of ovirt engine is this? How did you install -- fresh installation, upgrade? From source or rpm?

ovirt, postfix and sendmail
by Fabrice Bacchella 06 Jul '18

06 Jul '18

ovirt in version 4.2 choose to incorporate postfix as a mandatory MTA: yum erase postfix ... Removing: postfix x86_64 2:2.10.1-6.el7 @base 12 M Removing for dependencies: cockpit-ovirt-dashboard noarch 0.11.28-1.el7 @ovirt-4.2 15 M ovirt-host x86_64 4.2.3-1.el7 @ovirt-4.2 11 k ovirt-hosted-engine-setup noarch 2.2.22.1-1.el7 @ovirt-4.2 2.2 M Is there a way to change that ? It's not about postfix being inferior or superior to other solutions. It's that it didn't ask any thing, didn't check if one was already installed. It's just installed. For example: rpm -q --provides postfix MTA config(postfix) = 2:2.10.1-6.el7 postfix = 2:2.10.1-6.el7 postfix(x86-64) = 2:2.10.1-6.el7 server(smtp) smtpd smtpdaemon rpm -q --provides sendmail MTA config(sendmail) = 8.14.7-5.el7 sendmail = 8.14.7-5.el7 sendmail(x86-64) = 8.14.7-5.el7 server(smtp) smtpdaemon There is a lot of other dependencies to declare other than postfix, MTA would have been better.

Ovirt Networking Setup Questions
by Dave Mintz 06 Jul '18

06 Jul '18

Hello, I am trying to understand, by reading all available docs, how to correctly set up networking. What I have: 6 nodes, 1 engine - all have 3 nics. What I want: To separate traffic into three zones - ovirtmgmt, prod (for vm and admin web interface, data (for db access). So, I have three subnets - 10.10.10.0, 10.10.20.0, and 10.10.30.0 - with matching VLANs 10, 20, 30 I am trying to understand how bonding and bridging work. Should I bond all three nics together? The instructions here: https://www.ovirt.org/documentation/how-to/networking/bonding-vlan-bridge/ <https://www.ovirt.org/documentation/how-to/networking/bonding-vlan-bridge/> seem to do that and then create two bridges br0 and ovirtmgmt, which they then assign ip addresses to. I can do that, but shouldn’t I be configuring all of the networking at the logical network level? So, in that case, should I just create one bond/bridge and then do all of the networking at the logical level? Sorry if this is newbie stuff. Thanks Dave

Snapshots don't seem to work with Windows VMs
by jmp242＠cornell.edu 06 Jul '18

06 Jul '18

I've been testing with Windows 10 1607 LTSB and created several snapshots. I can preview each one, but they all boot with the same configuration and software installed and files as the "active VM" - so I cannot see at all how to roll back changes. Is this a known issue? I believe I'm following the documentation properly, but I can't see that the snapshots are doing anything. I'm testing on Scientific Linux 7.4 using oVirt 4.2.2.6-1.el7.centos.

oVirt LLDP Labeler
by Ales Musil 06 Jul '18

06 Jul '18

Hello, I would like to announce that oVirt LLDP Labeler is officially available. The Labeler is service that runs along with engine and is capable of labeling host network interfaces according to their reported VLANs via LLDP. The attached labels are named "lldp_vlan_${VLAN}", where ${VLAN} is ID of the corresponding VLAN. This can make work of an administrator easier, because any network with the same label, will be automatically attached to the corresponding host interface. The Labeler is currently tested only with Juniper switches which are capable of reporting all of their VLANs that are present on the interface. We would like to extend the Labeler with auto bonding feature. Those interfaces that are detected on the same switch would be automatically bonded. The Labeler source is available here: https://github.com/almusil/ovirt-lldp-labeler And the build: https://copr.fedorainfracloud.org/coprs/amusil/ovirt-lldp-labeler/ If you have any suggestions or problems please don't hesitate to report them on the GitHub page. -- ALES MUSIL Associate software engineer - rhv network Red Hat EMEA <https://www.redhat.com/> amusil(a)redhat.com IM: amusil <https://red.ht/sig>

GlusterFS 4.1
by Chris Boot 06 Jul '18

06 Jul '18

All, Now that GlusterFS 4.1 LTS has been released, and is the "default" version of GlusterFS in CentOS (you get this from "centos-release-gluster" now), what's the status with regards to oVirt? How badly is oVirt 4.2.4 likely to break if one were to upgrade the gluster* packages to 4.1? Thanks, Chris -- Chris Boot bootc(a)boo.tc
