It works pretty well: I can use the networks defined in Neutron, import them and when I launch VM instances from oVirt they get an internal-IP address from Neutron. A can also associate a floating IP to the Neutron port and get inbound connectivity for the virtual machine. The problem is that if I shutdown the VM (both from inside the VM itself and from the oVirt WEB GUI) the association port/internal-IP/floating-IP is lost and when the VM is booted again It will get a different internal-IP on a different port and I have to manually re-associate the floating-IP. It seems like we are currently creating a port on VM start and deleting the port on VM stop, which causes the behavior you described. Is there a way to keep the IP addresses when the VM is simply shutted down and not deleted? This is the behavior when using OpenStack: if I poweroff the VM, the IPs are kept for the future. There should be a way, would you mind reporting a bug on that? Moreover: can you confirm that in oVirt 3.3 there is still no support for the Neutron security rules? Unfortunately we did not get to handle that yet, but we are looking at that as part of extending the integration.

[Users] Gluster network info
Hello, I remember in the past that could be a problem to have high usage of ovirtmgmt network because engine sometimes detects hosts as unresponsive. And it should this the reason about bandwith limitation on vm migration, until dedicated network for it has been released. SO the question is : what about ovirtmgmt network for gluster replication when gluster domain is provided by ovirt nodes? I suppose it could be a problem too, couldn't it? In case I have a dedicated network for gluster for the nodes, how can i configure it? Can I configure in this case Gluster storage domain from ovirt engine or does it require to be on this network too? Thanks in advance for any suggestion Gianluca ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[Users] Bottleneck writing to a VM w/ mounted GlusterFS
Hello, I'm testing oVirt 3.3 with GlusterFS libgfapi back-end. I'm using a node for engine and one for VDSM. From the VMs I'm mounting a second GlusterFS volume on a third storage server. I'm experiencing very bad transfer rates (38MB/s) writing from a client to a VM on the mounted GlusterFS. On the other hand, from the VM itself I can move a big file from the root vda (libgfapi) to the mounted GlusterFS at 70MB/s. I can't really figure out where the bottleneck could be. I'm using only the default ovirtmgmt network. Thank you for your help, any hint will be appreciated. Regards, -- Stefano Stagnaro IT Manager Prisma Engineering S.r.l.

[Users] could not add iscsi disk in ovirt.
Hi guys, I am running ovirt with NFS as storage pool. Everything is working quite fine for me. The only problem is I could not add the a new iscsi disk in Disk tab. When I go to the Disk tab there is an option of adding new disk from internal storage and another option is add External (Direct Lun). When I opt for the External (Direct LUN), I am able to discover the Lun but could not log in to that lun using the ovirt web console. Whereas when I try to login to that lun using the isciadm in command line I am able to login. Any help?? ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[Users] Understanding Console Options
I'm trying to understand the various console options for a wiki page. Can someone make sure what I have in the attachments are right? Also when a VM is set to Spice and I open Console Options (at least in IE 10 for me, need to test further), it opens to Remote Desktop. Are these active yet? I don't see RDP as an option under Edit Console. Finally, is there any way to get the VNC option that we had in oVirt 3.2 that would pop up with a port number and password to use with a local client? - Nick attachment: console_spice.pngattachment: console_vnc.pngattachment: console_rdp.png___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [Users] Bottleneck writing to a VM w/ mounted GlusterFS
Are you duplicating the traffic over the same physical network by relaying through the VM, rather than writing directly to network storage, thereby halving the write performance? Assuming you're on a GigE network, are all the network devices running in full duplex? Just some guesses based on the fact that the throughput is almost exactly half. *Steve Dainard * IT Infrastructure Manager Miovision http://miovision.com/ | *Rethink Traffic* 519-513-2407 ex.250 877-646-8476 (toll-free) *Blog http://miovision.com/blog | **LinkedInhttps://www.linkedin.com/company/miovision-technologies | Twitter https://twitter.com/miovision | Facebookhttps://www.facebook.com/miovision * -- Miovision Technologies Inc. | 148 Manitou Drive, Suite 101, Kitchener, ON, Canada | N2C 1L3 This e-mail may contain information that is privileged or confidential.
