In ESX we use vSwitches (and there was a detail tutorial how to do this in pfSense manual), and everything works. But in oVirt, our only options seems to be to create VLANs for WAN and LAN and attach them to a NIC. When we boot pfSense we get no IP address for the WAN interface (we tried both static and dhcp). So, what we are looking for is some kind of howtos of how to install pfSense in oVirt. You can also evaluate the installation of the Neutron virtual appliance as described here [1]. The Neutron virtual appliance is an easy way to deploy OpenStack Neutron service within an oVirt environment: you can easily use Neutron from oVirt as an external networking provider starting from a ready to use image.

[ovirt-users] How long do your migrations last?
Hello list, Our storage domains are iSCSI on dedicated network, and when migrating VMs, the duration varies according to the size of the vDisks. The smallest VMs are migrated in about 20 seconds, while the biggest one may take more than 5 or 10 minutes. The average duration is 90 seconds. Questions : 1- Though I may have understood that the task of migration was made by the SPM, I don't know what it actually does? (which bytes goes where) 2- Do our times sound OK, or does it look like improvable? 3- What bottleneck should I investigate?

[ovirt-users] Ovirt 3.5.x Power failure recovery
Hi, Long time read-only user here :) Unfortunately I need some info which I can't seem to find in the archives and on Google. In the past 5 months we’ve had two very rare occasions of power failures in my hometown. First one was a ms during spike or drop, just enough to cause a reboot, the other was a 30min failure. Problem After the power failure my ovirt nodes boot into CentOS 6.6 and are running fine. In both cases my ovirt-engine-VM wouldn't start due to service Postgresql not starting. I tried some things before reverting back to an older DB snapshot that was on the VM disk, but still not working. Postgresql is not starting due to Duplicate UUID My solution Calm down girlfriend and don't sleep Reinstall 1 node, create new ovirt-engine, recreate VM's and copy VM disk data from old store to new store. Add second node Other solutions I can think of 1. Start cluster without reinstall ;) 2. Buy UPS (€150 one time, extra €60 yearly power usage = €450 in 5 years) At this moment I’m 1 click away from buying the UPS, but I prefer a more elegant solution. After the last power failure I did NOT reinstall my second ovirt node and the old engine is also on storage available. Is there someone that wants some data to troubleshoot/analyse? Or is this just one of those things? Buy the UPS and get on with your life? Short HW overview 2x ovirt 3.5.x (i3/32GB ram,1Gb eth VM network, dual x520 NFS eth) 1x NFS (i3/4GB ram, 5TB SAS and 6TB SATA on Dell PERC,1Gb eth mgmt, dual x520 10Gb) 1Gb is used for VM networking, the 10Gb is connected via DAC cables and runs NFS-storage. This works great! Whole cluster runs below 120w and VM disk performance is around 700MB/s :) I bought all the HW with power usage in mind, PicoPSU's and 35w CPU's in all nodes. So adding 30w extra just for the UPS feels a bit like killing an elephant with tissues... kind regards Raymond ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [ovirt-users] Directly connect NIC or other cards to VM?
I do physical layer testing of ethernet switches. I want to virtualize the test servers for scalability, reliability, and a VM solution allows easy change of system configuration. The bottom line is that testing often requires opening the network port in promiscuous mode to sniff traffic, many tests need to be able to use ethtool to view network properties (speed, duplex, link state, etc) and to set properties (auto-neg, forced speed, duplex, link state, etc). We use TOE cards which also allow offloading data from the CPU to the card allowing higher throughput, some tests we use this to send ~1Gbps traffic and monitor the data rate. So there are multiple scenarios, the main one being the ability to see and set physical layer properties, the other being able to offload traffic for maximum throughput. The latter can possibly be accomplished through OS layer drivers on the hypervisor but the former requires better driver access than what i currently see in the VM.

Re: [ovirt-users] mixing tagged and untagged vlans on a same interface
Hi, it is possible to achieve the state you describe. You just can’t have ovirtmgmt as VM network in such case. You need to set ovirtmgmt as nonVM [1] (aka bridgeless network), then you can put it on one interface with VLANs. Be aware that you can put on one interface only one bridges network + multiple VLANs.

Re: [ovirt-users] How long do your migrations last?
I’m under the impression it depends more on the hosts memory assignment than disk size. libvirt has to synchronize that over your networking setup. Your times sound like mine over 1G ethernet with a 9000 MTU, most of my machines are 1-4GB ram. I’ve another setup with a 10G backend that can migrate larger machines much faster. Things that do a lot of memory access (databases, say) or use more of their allocated memory, tend to take longer to migrate as it’s more work for libvirt to get it synchronized. A 10G+ backend is the best way to speed this up, and there are libvirt variables you can tweak to allocate more bandwidth to a migration (and the # of simultaneous migrations you allow). I think the defaults are 3 at max of 30% of your available bandwidth. I don’t think this takes bonds into account, so if you have bonded connections, you may be able to allocate more % or allow more simultaneous migrations. Keep in mind that if you’re sharing bandwidth/media with iSCSI, that some bandwidth will be needed there as well, how much depends on your storage load. A dedicated NIC could definitely help, especially if you’re trying to tune libvirt for this. -Darrell On Feb 13, 2015, at 8:53 AM, Nicolas Ecarnot nico...@ecarnot.net wrote: Hello list, Our storage domains are iSCSI on dedicated network, and when migrating VMs, the duration varies according to the size of the vDisks.

Any ideas welcomed. -- Nicolas Ecarnot If we speak about migration of VMs - relocating qemu process - than speed depends mostly on memory change pressure. The more changes per second the more restart the process needs. Best solution to speed it up is to enlarge migration_max_bandwidth in /etc/vdsm/vdsm.conf from default 30MB/s to something higher. We use 150Mb/s in 10Gbit network. With default we have seen migrations that will not come to an end. When talking about disks. It depends on how many disks you have attached to a single VM. The more disks and the more similar their sizes they are the faster you can migrate/operate on them. For example take a SAP system with 3 disks of 20GB system 20 GB executables and 300GB database. When issung disk operations (like snapshots) they will start in parallel for each disk. Disk operations will finish earlier for smaller disks. So in the end you will have only one operation left that may take hours. E.g. delete snapshot will start at ~220MB/s when running with three disks and end at ~60MB/s when only one disk snapshot deletion is active. Best regards.

[ovirt-users] Port mirroring outside traffic into a VM?
I have a network traffic monitor that is on a physical machine right now. It has two network interfaces: one with an IP on a regular switch port, and one without an IP on a switch port that is the target of a port mirror/monitor session for the desired VLAN. I'd like to move this system to an oVirt VM (I'm running 3.5.1). Is this the right way to go about it (and still have the VM migratable)? - I have several hosts with extra network interfaces; pick at least a couple, connect them to switch ports that are configured for mirror/monitor session. - In oVirt admin console, choose the Networks tab, click New. Give the network a name (like monitor), leave VLAN tagging de-selected and VM Network selected. Under the Cluster section, de-select Required (because the mirror won't go to all hosts). Click OK to create. - Click on the network, select the vNIC Profiles tab, edit the default profile and select Port Mirroring. - Go to the Hosts tab. For each host with a port mirror, click on the host, then choose the Network Interfaces tab and Setup Host Networks. Drag the new network to its attached port, click the pencil, and set Boot Protocol to None. - Go to the Virtual Machines tab. Click on the VM, choose the Network Interfaces tab, and click New. Choose the monitor network in the Profile. -- Chris Adams c...@cmadams.net ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
