Virtualized server & oVirt Node on different subnets
by andreil1 19 Dec '17

19 Dec '17

Hi, I have oVirt node running on internal network, address range 192.168.0.x, and need to install virtualized server on DMZ zone 192.168.1.x. Server has several NICs. DMZ NIC will be connected directly to router with firewall. What is the best solution ? 1) Undefine one NIC on CentOS host / node, and assign IP on virtualized server in passthrough mode. 2) Create 2nd oVirtmgmt bridge and link it to NIC on DMZ (if thats possible at all). Thanks in advance. Andrei

Host has not default route
by Roberto Nunin 19 Dec '17

19 Dec '17

Hi all I'm doing further tests deploying from scratch, with the same hardware, one Gluster based hyperconverged LAB. I'm deploying ovirt-node'ng with ISO image: ovirt-node-ng-installer-ovirt-4.2-pre-2017121416. All the process works fine, no more hangs when HE deploy is at the end. Hosts 2 and 3 now can be imported (insted to be added). Storage main domain is added and HE storage automatically imported. One issue: Host 2 and 3 show me: Host has no default route In Host> General tab. Moreover I'm not able to migrate HE, even if the hosted-engine --vm-status looks good, like in the attachment. Could the issue of "Host has no default route" blocking migrations ? Hosts are online, all of three. How to work around the "Host has no default route" message ? I've seen a bug, 1477589, but no solution, till now. Any hints ? -- Roberto Nunin

Ovirt with Hosted Engine and 4 Hosts
by Gabriel Stein 19 Dec '17

19 Dec '17

Hi all, I know, that oVirt with Hosted Engine requires a replica 3 glusterfs volume, but I'm using 4 nodes and I would like to know if is possible to add it to the glusterfs engine volume. Or should I always use 3, 5 and 7 hosts with hosted-engine? What I'm doing: gluster volume add-brick engine server1:/gluster/engine/brick1 server2:/gluster/engine/brick1 server3:/gluster/engine/brick1 server4:/gluster/engine/brick1 Error: volume add-brick: failed: Incorrect number of bricks supplied 4 with count 3 If I'm using replica 3 will not be possible, but how can I upgrade it? Adding 2 more nodes and upgrade to replica 5? Thanks in Advance! Best Regards Gabriel Stein Gabriel Stein ------------------------------ Gabriel Ferraz Stein Tel.: +49 (0) 170 2881531

Q: oVirt Node Update Wiped my Updates
by Andrei V 18 Dec '17

18 Dec '17

Hi ! I have updated today oVirt node 4.1 via yum, installed from oVirt DVD. Update was a minor version change. Now all software I had installed, including mc, Samba, etc. have been lost. Looks like oVirt node is being updated with whole system 600MB image, not just with rpms (please correct if I'm wrong here). Keeping my manually installed software is crucial, since it has UPS and hardware RAID monitor. Can anyone suggest if this is normal behavior or a single glitch ? So far I found only this instruction for node installation: https://www.ovirt.org/documentation/install-guide/chap-oVirt_Nodes/ And it uses pre-made DVD ISO, not manual install with RHEL/CentOS DVD and RPMs from yum repository. Thanks in advance for any suggestion(s). Andrei

Self-Hosted engine 4.1.7 unavailable from the outside of the host
by Matteo Capuano 18 Dec '17

18 Dec '17

Hi everyone, my name’s Matteo and I’m a new oVirt user. I’m trying to install the gluster hyperconverged solution in a lab environment following the How-To wrote by Jason Brooks: https://ovirt.org/blog/2017/04/up-and-running-with-ovirt-4.1-and-gluster-st… Sadly, I cannot understand how to configure the network on the self-hosted engine and I’m unable to make it available from outside the host. As written in the HowTo I created three hosts (ovirt-note 4.1.7) each one with two nics, one for gluster and one for management, the network is a static LAN with FQDN resolvable (also reverse) by a local DNS. Here the details: Gateway: 172.16.1.1 DNS: 172.16.1.12 Host1: 172.16.1.210 (management) – 172.16.2.210 (gluster) Host2: 172.16.1.220 (management) – 172.16.2.220 (gluster) Host3: 172.16.1.230 (management) – 172.16.2.230 (gluster) Engine: 172.16.1.200 When installing the engine I choose to brigde the management’s nic (172.16.1.210) of host1 but, once the installation is completed, I'm unable to reach the engine from the LAN where the hosts are connected. The engine (172.16.1.200) can ping only host1 (172.16.1.210) and only host1 can ping the engine. As far as my network knowledge goes, to make the engine available from the outside of host1 I would need to use a third nic or to use some device to associate the ip and MAC address of the engine’s nic. I’ve looked around over the internet for a solution but every how-to I’ve found follows the same steps of Jason’s. I’ve also already asked for help to Jason. Anyone could help me to solve this issue? Thank you Matteo

Empty cgroup files on centos 7.3 host
by Florian Schmid 18 Dec '17

Hi, I wanted to monitor disk IO and R/W on all of our oVirt centos 7.3 hypervisor hosts, but it looks like that all those files are empty.

Looking at this post: http://lists.ovirt.org/pipermail/users/2017-January/079011.html this should work. Is this normal on centos 7.3 with oVirt installed? How can I get those values, without monitoring all VMs directly? oVirt Version we use: 4.1.1.8-1.el7.centos BR Florian

Option to put host into maintenance after installation of new host
by Florian Schmid 18 Dec '17

18 Dec '17

Hi, would it be possible for future releases to add an option to the add new host tab to put the host in maintenance after installation instead of activating it. The same would be for reinstall. I have the problem now, that all hosts after installation will be activated, but network is not configured yet. Therefore host will be in non operational state and will be rebooted immediately. The only solution I have now is to configure power management after the host has all networks configured. I want to have all my networks as required, because otherwise someone will forget to add all of them and then you have other issues. BR Florian
