Ovirt Node 4.3.6 Logical Network Issue - Network Down
by jeremy_tourville＠hotmail.com 22 Oct '19

22 Oct '19

I have built a new host and my setup is a single hyperconverged node.. I followed the directions to create a new logical network. I see that the engine has marked the network as being down. (Hosts>Network Interfaces Tab>Setup Host Networks) Here is my network config on the host- [root@vmh ~]# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enp96s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master ovirtmgmt state UP group default qlen 1000 link/ether 0c:c4:7a:f9:b9:88 brd ff:ff:ff:ff:ff:ff 3: enp96s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 0c:c4:7a:f9:b9:89 brd ff:ff:ff:ff:ff:ff inet 172.30.51.2/30 brd 172.30.51.3 scope global noprefixroute dynamic enp96s0f1 valid_lft 82411sec preferred_lft 82411sec inet6 fe80::d899:439c:5ee8:e292/64 scope link noprefixroute valid_lft forever preferred_lft forever 19: ;vdsmdummy;: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 96:e4:00:aa:71:f7 brd ff:ff:ff:ff:ff:ff 23: ovs-system: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 36:0f:60:69:e1:2b brd ff:ff:ff:ff:ff:ff 24: br-int: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether f6:3b:14:e1:15:48 brd ff:ff:ff:ff:ff:ff 25: ovirtmgmt: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 0c:c4:7a:f9:b9:88 brd ff:ff:ff:ff:ff:ff inet 172.30.50.3/24 brd 172.30.50.255 scope global dynamic ovirtmgmt valid_lft 84156sec preferred_lft 84156sec inet6 fe80::ec4:7aff:fef9:b988/64 scope link valid_lft forever preferred_lft forever 26: vnet0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master ovirtmgmt state UNKNOWN group default qlen 1000 link/ether fe:16:3e:50:53:cd brd ff:ff:ff:ff:ff:ff inet6 fe80::fc16:3eff:fe50:53cd/64 scope link valid_lft forever preferred_lft forever VLAN 101 is attached to enp96s0f0 which is my ovirtmgmt interface. -IP range 172.30.50.x VLAN 102 is attached to enp96s0f1 which is my storage NIC for gluster. -IP range 172.30.51.x VLAN 103 is attached to enp96s0f1 is intended for most of my VMs that are not infrastructure related. -IP range 192.168.2.x I am pretty confident my router/switch is setup correctly.. As a test, I can go to localhost>networking>add VLAN and assign enp96s0f1 to VLAN 103 and it does get an IP address in the 192.168.2.x range. The host can also ping the 192.168.2.1 gateway. Why doesn't the engine think the VLAN is up? Which logs do I need to review?

Fwd: Re: Can ovirt-node support multiple network cards ？
by Roberto Nunin 22 Oct '19

22 Oct '19

If I've understood clearly, your goal is to have two physical network interfaces connected to one logical network in ovirt-engine. If this is the case, you can use bonding/teaming physical interfaces into one and then connect that aggregation to the ovirt-engine logical network. Moreover, as Jeremy stated, you can use that aggregated physical interfaces to transfer VLANs, taking advantages on redundancy/resilience and configuration flexibility.

Help/guidelines/ideas on how to create new hosted-engine on final server with old config
by Lars Bækmark 21 Oct '19

21 Oct '19

I'm looking for guidelines/ideas for moving/migrating/Hosted-engine from the initial install with local storage, to the "Final" server. Initial it was a "Test" to see if this will work or not, but this has now become the production, where the initial host named "ovirt" that is hosting the hosted-engine on local storage is "just" doing that. My hosted-engine is called "ovirtmgr" and I created a new host to run Virtual machines called "Hermod" - getting better in the naming thing, right? This test was so successful that I converted the old Xen/Oracle based host to CentOS 7 - the same as host Ovirt and Hermod: Linux hermod 3.10.0-1062.1.1.el7.x86_64 #1 SMP Fri Sep 13 22:55:44 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux <https://www.facebook.com/linux.lanka?fref=gs&__tn__=%2CdK-R-R&eid=ARDadyp9k…> Linux fernis 3.10.0-1062.el7.x86_64 #1 SMP Wed Aug 7 18:08:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux oVirt version is: 4.3.5.4-1.el7 I want to move the hosted-engine to Fenris and at the same time use a NFS share for that. I can shut the whole setup down, as long as it runs again in daytime. I do know that I should have started with the hosted-engine in the correct place, but that's not the case anymore. There are eleven VM’s in total Can anyone suggest a plan on how to move/create a new hosted-engine on my server Fenris? The history of the old server is not important, I just want the hosted-engine on fenris using NFS share I did find some sugesting on the web, but they all look quite complicated: https://www.ovirt.org/…/engine/migrate-to-hosted-engine.html <https://l.facebook.com/l.php?u=https%3A%2F%2Fwww.ovirt.org%2Fdevelop%2Fdeve…> I just love the product! I'm now running VM's 2-3 times faster by converting from Xen to KVM, but still use the same storage and server! :-D Appreciate any help! 😀 /Lars Lars Bækmark lars(a)baekmark.dk <mailto:lars@baekmark.dk> +45 2241 0500 Mølleengen 6 3550 Slangerup Danmark ------------------------------------- Oversteer is when you hit the wall with the rear of the car.

Try switching off the lanplus (maybe remove it at all).

Re: improve file operation speed in HCI
by Strahil 18 Oct '19

If you seek performance, then set tuned-adm profile in the VM to 'throughput-performance' and scheduler either 'noop' or 'none' (depends if multi queue is enabled). Usually, if yhou crete the gluster cluster via cockpit and then install the hosted engine via cockpit again - all options on your gluster volumes are the most optimal you need.
