Hello, Fresh 4.3 Cluster : I imported a 4.2 export domain, copied the vm on the newly provisioned gluster Volume with VDO I then tried to create a clone of a 50GB thin provisionning vm anddisconnected This morning I can not log in Engine Manager even after rebooting hosted-engine : I get this message in UI and logs when I click "Administration Portal" 2019-02-08 09:40:51,706+01 ERROR [org.ovirt.engine.core.aaa.servlet.SsoPostLoginServlet] (default task-1) [] org.apache.commons.lang.SerializationException: org.codehaus.jackson.map.JsonMappingException: Can not deserialize instance of java.util.LinkedHashMap out of START_ARRAY token at [Source: java.io.StringReader@f832283; line: 724, column: 25] (through reference chain: org.ovirt.engine.core.common.action.CloneVmParameters["watchdog"]->org.ovirt.engine.core.common.businessentities.VmWatchdog["specParams"])

Network Performance Issues
by Bryan Sockel 08 Feb '19

08 Feb '19

Hi, I currently have a 4 node ovirt cluster running. Each node is configured with an active passive network setup, with each link being 10 GB. After looking over my performance metrics collected via observium. I am noticing the network traffic rarely exceeds 100 MB. I am noticing this across all four of my servers and my 2 storage arrays that are also connected via the same 10 GB links. What is the best way to trouble shoot this problem? Thanks

need network design advice for iSCSI
by John Florian 08 Feb '19

08 Feb '19

I have an existing 4.2 setup with 2 hosts, both with a quad-gbit NIC and a QNAP TS-569 Pro NAS with twin gbit NIC and five 7k2 drives. At present, the I have 5 VLANs, each with their own subnet as: 1. my "main" net (VLAN 1, 172.16.7.0/24) 2. ovirtmgmt (VLAN 100, 192.168.100.0/24) 3. four storage nets (VLANs 101-104, 192.168.101.0/24 - 192.168.104.0/24) On the NAS, I enslaved both NICs into a 802.3ad LAG and then bound an IP address for each of the four storage nets giving me: * bond0.101@bond0: 192.168.101.101 * bond0.102@bond0: 192.168.102.102 * bond0.103@bond0: 192.168.103.103 * bond0.104@bond0: 192.168.104.104 The hosts are similar, but with all four NICs enslaved into a 802.3ad LAG: Host 1: * bond0.101@bond0: 192.168.101.203 * bond0.102@bond0: 192.168.102.203 * bond0.103@bond0: 192.168.103.203 * bond0.104@bond0: 192.168.104.203 Host 2: * bond0.101@bond0: 192.168.101.204 * bond0.102@bond0: 192.168.102.204 * bond0.103@bond0: 192.168.103.204 * bond0.104@bond0: 192.168.104.204 I believe my performance could be better though. While running bonnie++ on a VM, the NAS reports top disk throughput around 70MB/s and the network (both NICs) topping out around 90MB/s. I suspect I'm being hurt by the load balancing across the NICs. I've played with various load balancing options for the LAGs (src-dst-ip and src-dst-mac) but with little difference in effect. Watching the resource monitor on the NAS, I can see that one NIC almost exclusive does transmits while the other is almost exclusively receives. Here's the bonnie report (my apologies to those reading plain-text here): Bonnie++ Benchmark results *Version 1.97* *Sequential Output* *Sequential Input* *Random Seeks* *Sequential Create* *Random Create* Size Per Char Block Rewrite Per Char Block Num Files Create Read Delete Create Read Delete K/sec % CPU K/sec % CPU K/sec % CPU K/sec % CPU K/sec % CPU /sec % CPU /sec % CPU /sec % CPU /sec % CPU /sec % CPU /sec % CPU /sec % CPU unamed 4G 267 97 75284 21 22775 8 718 97 43559 7 189.5 8 16 6789 60 +++++ +++ 24948 75 14792 86 +++++ +++ 18163 51 Latency 69048us 754ms 898ms 61246us 311ms 1126ms Latency 33937us 1132us 1299us 528us 22us 458us I keep seeing MPIO mentioned for iSCSI deployments and now I'm trying to get my head around how to best set that up or to even know if it would be helpful. I only have one switch (a Catalyst 3750g) in this small setup so fault tolerance at that level isn't a goal. So... what would the recommendation be? I've never done MPIO before but know where it's at in the web UI at least. -- John Florian

vm autostart and priorities
by Hetz Ben Hamo 07 Feb '19

Hi, I'm migrating my VM's to oVirt from ESXI and I've only got one left on the ESXi side - a VM which provides me DNS, mail and DHCP services. Without this VM's, I can't access the internet. The only issue that prevents me from migrating this VM to oVirt and "kill" the ESXi machine, is that I need to start this VM's upon oVirt node power up (auto start), so if the power goes down and comes back, I'll have my infrastructure up and running automatically within minutes. Is there a way to auto start specific VM's or better - start VM's based on specific orders upon boot of the nodes? I think it's a very important feature. Thanks
