Evaluate oVirt to remove VMware
by dsalade＠gmail.com 28 Aug '19

28 Aug '19

Howdy All!!! Somewhat new user to Linux and having some issues with oVirt node networking. We are mainly a Windows/VMware medium shop but have a pretty good network. Our VMware setup has redundant switches using multiple VLANs. This was fairly easy to setup with VMware. We never had an issue with VMware, add 2 NICs to the ESXi host and then adding VLANs into the Virtual Switch. Biggest issue I am having, should I be bonding, teaming and VLANing on top of that? Tried setting up node with Engine inside which fails to deploy because of networking. Then I tried a standalone Engine and could not add node to it - I believe networking as well as Power Management agent was the problem. Would like the nodes/engine to be on one subnet (lets say 10.10.11.x) and VMs to be allowed to run there are well as 10 other VLANs. I guess welcome to the wonderful world of Linux networking and learning some new technologies is in store for me. I hope I am not being vague, like I said fairly new to Linux. Thanks for any responses! Allen

Dear oVIrt, Would you be so kind to help me/tell me or point me how to find which Hooks, and in which order, are triggered when VM is being migrated? Kindly awaiting your reply. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic

Hm... It was supposes to show controller status. Maybe the hpssacli you have is not supporting your raid cards.Check for newer version on HPE's support page.

Curtis, Do you have enough space to run tcpdump (port not 22) on both hosts and on the small VM you have done previously - and then start the migration?

What is your bandwidth threshold for the network used for VM migration ? Can you set a 90 mbit/s threshold (yes, less than 100mbit/s) and try to migrate a small (1 GB RAM) VM ? Do you see disconnects ? If no, try a little bit up (the threshold) and check again. Best Regards, Strahil NikolovOn Aug 23, 2019 23:19, "Curtis E.

Moving ovirt engine disk to another storage volume
by Erick Perez - Quadrian Enterprises 25 Aug '19

25 Aug '19

Good morning, I am running Ovirt 4.3.5 in Centos 7.6 with one virt node an a NFS storage node. I did the self-hosted engine setup and i plan to add a second virt host in a few days. I need to do heavy maintenance on the storage node (VDO and mdadm things) and would like to know how (or a link to an article) can I move the ovirt engine disk to another storage. Currentl the NFS storage has two volumens (volA,volB) and the physical host have spare space too. Virtual machines are in VolB and the engine is in VolA. I would like to move the engine disk from VolA to VolB or to local storage. BTW I am not sure if I should say "move the engine" or should I say move "hosted_storage domain" domain thanks in advance. --------------------- Erick Perez
