If you do have SSD on your physical hosts, have you considered building gluster volume using these? This could give you improved performance. Regarding performance, I think it is best that you run a test comparing gluster storage performance with local storage and see if this is acceptable to you. Please share the results in case you do.

If any host goes down, the data is available on the remaining 2 nodes, and the VMs can be migrated to other nodes. Yes, I know, but I'm already worried about corruption issues due to possible gluster bugs or performance problems under heavy load. I don't think what you ask for is possible automatically. If you want local storage to gluster volume backup, you would need 1-1 mapping. i.e each local storage domain has its own gluster volume backup.You could then import the storage domain that's backed up on the gluster volume and start the VMs on the remaining hosts.

I think you are right, for upgrades done from the engine - not 'yum update'. 'Move to maintenance and reinstall' and 'Upgrade from the engine' are actually almost the exact same thing, from the engine's POV. Thanks for the comment.

Re: [ovirt-users] Storage questions
Hi, As on oVirt is it possible to attach local storage I supose it can be used to run virtual machines: I have drawn a couple of diagrams in order to know if is it possible to set up this configuration: 1.- In on-going scenario: Every host runs 100 vdi virtual machines whose disks are placed on local storage. There is a common gluster volume shared between all nodes. [image: Imágenes integradas 1] 2.- If one node fails: [image: Imágenes integradas 2] oVirt has to be able to inventory the copy of machines (in our example vdi201 ... vdi300) and start them on remaining nodes. ¿Is it possible to reach this configuration with oVirt? ¿or something similar? Making backup with the import-export procedure based on snapshot can take lot of time and resources. Incremental rsync is cheaper in terms of resources.

[ovirt-users] Network usage in ovirt dashboard?
Is there a way to configure what data gets shown in the dashboard? Specifically, I'd like to see network usage. It would be nice to see total network usage on the dashboard, and have a graph of per-VM network usage as well. The closest I've found is the "Total" columns on the Network -> Virtual Machines page. I'd like to see something sort of like the CPU/RAM/Storage (over)commit graphs.

The server dosn't power off and will reboot after some "kernel panic" error.

Re: [ovirt-users] Storage questions
I suggest you setup that environment and test for the performance and report if you have issues. Please note that currently there is no data locality guarantee, so a VM might be running on a host that doesn't have its disks. We have APIs to do backup\restore and that is the only supported option for backup: https://www.ovirt.org/develop/release-management/features/storage/backup-restore-api-integration/ You can look at the Gluster DR option that was posted a while back, you can look that up. It used geo replication and import storage domain to do the DR.

But I also do not think oVirt will overwrite your conf by any other process, so you can also simply do this manually.

Re: [ovirt-users] HELP ESXI SERVER UNDER OVIRT-ENGINE
I wanna to use esxi hosts as a ovirt nodes. Becouse esxi is free but vcentre is expensive. I wanna to learn can I create cluster with esxi ovirt-nodes on open virtulaztion manager console. 2016-11-22 11:16 GMT+03:00 Luca 'remix_tj' Lorenzetto < lorenzetto.l...@gmail.com>: > On Tue, Nov 22, 2016 at 9:11 AM, Ali Mumcu wrote: > > Hello, > > > > https://xrsa.net/2014/08/25/running-vmware-esxi-under-ovirt/ > > I found this guide it shows how to run esxi under ovirt . > > ıs it possible for you? > > I only wanna to use open source system to manage high avability (like > > vcenter but open source). > > The link you provided is for running ESXi as a guest on ovirt.

The link you provided is for running ESXi as a guest on ovirt. Not for managing a vmware cluster through ovirt. If i can give you a suggestion, use vcenter if you want to use esxi as hypervisor or use ovirt completely. Ovirt, from my tests (i'm migrating from vmware) can provide all the performances you need. > > > Also does manageiq manage high avability for esxi servers vms?

Re: [ovirt-users] HELP ESXI SERVER UNDER OVIRT-ENGINE
Hello, https://xrsa.net/2014/08/25/running-vmware-esxi-under-ovirt/ I found this guide it shows how to run esxi under ovirt . ıs it possible for you? I only wanna to use open source system to manage high avability (like vcenter but open source). Also does manageiq manage high avability for esxi servers vms?
