[ovirt-users] Need VM run once api
Hi Experts, We are integrating ovirt with our internal cloud. Here we installed cloudinit in vm and then converted vm to template. We deploy template with initial run parameter Hostname, IP Address, Gateway and DNS. but when we power ON initial, run parameter is not getting pushed to inside the vm. But its working when we power on VM using run once option on Ovirt portal. I believe we need to power ON vm using run once API, but we are not able get this API. Can some one help on this. I got reply on this query last time but unfortunately mail got deleted.

[ovirt-users] automatic migration on power failure
Hi, is ovirt by default not capable of automatic migration or automatic restarting of VMs on different host during host's power failure? because i remember having this problem on hosted-engine setup wherein my engine as well as the other virtual machines won't automatically start on different host when i for example switch off the server hosting the VMs. migration when host switched to maintenance works fine as well as the migration using the cluster policy. HA option on VM also works fine, but it only restarts on the same host. below is our current setup. 1 SuperMicro X7DBR-3 (Engine ovirt 3.5.1.1-1.el6) 6 IBM S5000PAL (Hosts) FreeNAS multipath iSCSI for data storage kvm 0.12.1.2 - 2.448.el6_6.4 libvirt libvirt-0.10.2-46.el6_6.6 vdsm vdsm-4.16.20-1.git3a90f62.el6 Thanks, Jaicel ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [ovirt-users] Poor guest write speeds
Hello again. So I have been doing some more testing just to be sure. I performed a reboot of my Win7 ESXi guest VM between each running of the Parkdale HDD speed test app, just to be absolutely sure the results were not a result of caching and each time I get pretty consistent results: no less than 60 MByte/s Seq. Write and around the same for Seq. Read. In oVirt, is there some tuning I am maybe missing? Is there a different HDD type I should be selecting (or converting to)? -Alan On 27/07/2015 6:34 PM, Alan Murrell wrote: Hello, So a bit of an update, though I still have some additional testing to do. I installed ESXi 5.5 on the same hardware (blew away my oVirt install) and installed a Windows 7 VM, with same settings (2GB RAM, 1 single-core vCPU, 60GB thin-provisioned HDD) The install of Windows itself was definitely *way* faster. I don't have actual timings for real comparisons, but I can say with 100% certainty that the install was faster. I would say it took at *least* half the time to install as oVirt, though to be honest, I would have to say it was maybe 1/3 of the time. Once installed, I installed the VMware Guest Tools, then downloaded and ran the Parkdale app with the same settings I ran it under the Windows 7 VM. The preliminary results are interesting. The Seq. Write test comes up at around 65 MByte/s, which compares well to the bare metal results I got previously. What is interesting (and disappointing) is that the Seq. Read test indicates about 65MByte/s, which is a *huge* decrease to what I was getting in the oVirt Win7 guest. As I mentioned, still going to do some additional testing, but wanted to let you know that -- initially, anyway -- the problem under oVirt does not seem to be a hardware-related issue, but possibly something with the virtio-SCSI? For those who are running Windows VMs in production, what sort of performance do you see? What type of virtual HDD are you running? I will post back either later or some time tomorrow (Tue) with more results. -Alan Quoting Alan Murrell li...@murrell.ca: Hello, I am running oVirt 3.5 on a single server (hosted engine). I have two Western Digital WD20EZRX drives in a hardware RAID1 configuration. My storage is actually on the single server, but I am attaching to it via NFS. I created a Windows 7 guest, and I am finding its write speeds to be horrible. It is a VirtIO-SCSI drive and the guest additions are installed. The installation of the OS took way longer than bare metal or even VMware. When I ran Windows updates, it again took a *lot* longer than on bar metal or on VMware. The read speeds seem to be fine. The guest is responsive when I click on programs and they open about as fast as bare metal or VMware. I downloaded and ran Parkdale HDD tester and ran a test with the following settings: - File size: 4000 - Block Size: 1 MByte The results are as follows: - Seq. Write Speed: 10.7 MByte/sec (Random Q32D: ) - Seq. Read Speed: 237.3 MByte/sec (Random Q32D: ) I ran another test, but this time changing the Block Size to 64 kByte [Windows Default].

As you can see, it is significantly higher than what I am getting in the Windows guest VM. Running that same dd test on an Ubuntu guest VM gives me 24MB/s. Any ideas why I have such poor write performance? Is this normal with oVirt guests? Any ideas on what I might be able to do to improve them? I don't expect to get close to the bare metal results, but maybe something in the 40-60 MB/s range would be nice.

[ovirt-users] Data Center becomes Non Responsive when I reboot a host
Hello ovirt users, I have 4 hosts with a distributed replicated 2x2 GlusterFS storage. (oVirt3.5/CentOS7) When I reboot a host (in maintenance mode and not my SPM host) my Data Center becomes Non Responsive, my storage becomes red and inactive, and many VMs become paused due to unknown storage error. The same happens if I administratively set ovirtmgmt network down (to a host in maintenance mode and not my SPM host) with ifconfig ovirtmgmt down. I know that management network (ovirtmgmt) is required by default and is part of oVirt monitoring process but is there anything I can do in order to reboot a host without causing this mess?

Re: [ovirt-users] Poor guest write speeds
I was asking because in ovirt you may have had that option turned on, and in just regular libvirtd/kvm you didn't. It could be making a difference, but its really hard to tell. It's very strange that you're having write performance issues. This is one of the reasons I use oVirt. Performance has always been top notch compared to any other comprehensive solution I have tried. Can you give this a try. Fire up a manager thats not hosted engine, maybe a vm on a laptop or something. And then add that centos install you already as a node in a datacenter that uses local storage. ... I have a feeling you might have had some NFS related issues with your write performance. If that is the case, then NFS tuning will be required to get what you are looking for. To be honest this has never been a problem for me in any of my deployments, so if anyone else out there has something please feel free to chime in.

[ovirt-users] Neutron Appliance questions
Hello, I have an oVirt 3.5.x install on CentOS 7.1, and I'm trying to wrap my head around how to use the Neutron appliance. In the video demo, two hosts attach the neutron network to their eth1 interfaces, and their VMs can communicate with each other. But the demo doesn't go on to show how to connect those VMs to the internet with floating IPs. In the OpenStack Neutron videos I've watched on youtube, the common basic configuration seems to be a single 'network node' that connects to the public and private networks and routes to the 'compute nodes', which aren't connected to the public network. With the oVirt/Neutron integration, it seems like all hosts are both 'network' and 'compute' nodes, meaning that they need to be connected to the public network. Is that right, or am I missing some fundamental concept? Is it possible to designate 1 or 2 hosts of a cluster (with public network access) for the neutron appliance, while the remaining hosts only have private network access + floating IPs for VMs?

Re: [ovirt-users] Poor guest write speeds
For my latest test, I installed CentOS7 on my server and then installed the libvirt/KVM virtualization group. I created a Win7 guest VM giving it 2GB RAM, 1 vCPU, and 60GB HDD. I did not specify anything for the HDD type; just whatever the default is for libvirt. The install of Win7 went *way* faster than any bare metal install I have ever done of Win7, and also faster than the ESXi install I had done earlier. Once installed, I downloaded the same Parkdale HDD testing application I have been using, and used the same settings. The write test results were about 100 MByte/s. I ran the test several times, including rebooting between tests, and the results came back consistent. As a baseline, I ran the following modified 'dd' write test on the server itself: dd bs=1M count=4000 if=/dev/zero of=test conv=sync with the following results: 4000+0 records in 4000+0 records out 4194304000 bytes (4.2 GB) copied, 39.349 s, 107 MB/s So now the question becomes, why would I be getting such a huge difference in oVirt?

Re: [ovirt-users] Ovirt and Gluster
Hi, That does not provide any answers to the OP's questions. And it also still fails to *explicitly* mention that gfapi acceleration is not available unless you use oVirt 3.6.0 (which AFAIK is still in beta). I raised a documentation bug about that many months ago and I still feel it has not been adequately addressed (ie all the Feature Complete entries on the page you link suggests it's ready in Stable releases). He asked about a production scenario. For all that are interested, I've had very poor results including VM image corruption on my home setup using plain old KVM on top of GlusterFS. If I can't even get a home infrastructure working to my satisfaction, what hope is there for a corporate production environment? I appreciate that this is not really the oVirt teams fault, but a lot of us are really frustrated in trying to find a reliable setup for oVirt/GlusterFS and keep banging our heads against the same wall. For now for production loads on oVirt/RHEV, we'll be firmly sticking to iSCSI for our VM storage - I'd rather even roll my own failover using DRDB/corosync/pacemaker for the lowest capex. We'd love it if we could use Ceph RBD but for some reason RedHat don't seem to want to drive that, rather relying on OpenStack Cinder as an intermediary, which seems silly for a pure Virtualisation setup (ie not a multi-tenanted private cloud). Perhaps, being from RedHat, you could suggest the closest community versions of oVirt and Gluster to your commercial equivalents of RHEV/RHSS?

That just seems like one heck of a performance drop-off to me, which means I either don't have something configured/tuned properly, or virtio-SCSI is not that good (though everything I have rad suggests that virtio-SCSI is what I should be using for best performance, as long as the guest drivers are installed) -Alan Hello, I am running oVirt 3.5 on a single server (hosted engine). I have two Western Digital WD20EZRX drives in a hardware RAID1 configuration. My storage is actually on the single server, but I am attaching to it via NFS. I created a Windows 7 guest, and I am finding its write speeds to be horrible. It is a VirtIO-SCSI drive and the guest additions are installed. The installation of the OS took way longer than bare metal or even VMware. When I ran Windows updates, it again took a *lot* longer than on bar metal or on VMware. The read speeds seem to be fine. The guest is responsive when I click on programs and they open about as fast as bare metal or VMware. I downloaded and ran Parkdale HDD tester and ran a test with the following settings: - File size: 4000 - Block Size: 1 MByte The results are as follows: - Seq. Write Speed: 10.7 MByte/sec (Random Q32D: ) - Seq. Read Speed: 237.3 MByte/sec (Random Q32D: ) I ran another test, but this time changing the Block Size to 64 kByte [Windows Default]. Results are as follows: - Seq. Write Speed: 10.7 MByte/sec (Random Q32D: ) - Seq. Read Speed: 237.3 MByte/sec (Random Q32D: ) On the host, running '|dd bs=1M count=256 if=/dev/zero of=test conv=fdatasync|' on my data mount via NFS rsuled in the following: 256+0 records in 256+0 records out 268435456 bytes (268 MB) copied, 3.59431 s, 74.7 MB/s I got this https://romanrm.net/dd-benchmark https://romanrm.net/dd-benchmark and measures the write speed of a disk. As you can see, it is significantly higher than what I am getting in the Windows guest VM. Running that same dd test on an Ubuntu guest VM gives me 24MB/s. Any ideas why I have such poor write performance? Is this normal with oVirt guests? Any ideas on what I might be able to do to improve them? I don't expect to get close to the bare metal results, but maybe something in the 40-60 MB/s range would be nice. Thanks, in advance, for your help and advice. -Alan ___ Users mailing list Users@ovirt.org mailto:Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [ovirt-users] Storage network question
Hi Patrick, On 27/07/2015 7:25 AM, Patrick Russell wrote: We currently have all our nics in the same bond. So we have guest traffic, management, and storage running over the same physical nics, but different vlans. Which bond mode do you use, out of curiousity? Not sure I would go to this extreme, though; I would still want the physical isolation of Management vs. network/VM traffic vs. storage, but just curious which bonding mode? Modes 1 and 5 would seem to be the best ones, as far as maximising throughput. I read an article just the other day where a guy detailed how he bonded four 1Gbit NICs in mode 1 (with each on a different VLAN) and was able to achieve 320MB/s throughput to NFS storage. As far as the storage question, I like to put other storage on the network (smaller NAS devices, maybe SANs for other storage) and would want the VMs to be bale to get at those. Being to use a NIC to carry VM traffic for storage as well as for host access to storage would cut down on the number of NICs I would need to have in each node. -Alan -Alan ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [ovirt-users] Poor guest write speeds
Are you using virtio-scsi in oVirt? On Jul 28, 2015 1:50 PM, Alan Murrell li...@murrell.ca wrote: For my latest test, I installed CentOS7 on my server and then installed the libvirt/KVM virtualization group. I created a Win7 guest VM giving it 2GB RAM, 1 vCPU, and 60GB HDD. I did not specify anything for the HDD type; just whatever the default is for libvirt. The install of Win7 went *way* faster than any bare metal install I have ever done of Win7, and also faster than the ESXi install I had done earlier. Once installed, I downloaded the same Parkdale HDD testing application I have been using, and used the same settings. The write test results were about 100 MByte/s. I ran the test several times, including rebooting between tests, and the results came back consistent. As a baseline, I ran the following modified 'dd' write test on the server itself: dd bs=1M count=4000 if=/dev/zero of=test conv=sync with the following results: 4000+0 records in 4000+0 records out 4194304000 bytes (4.2 GB) copied, 39.349 s, 107 MB/s So now the question becomes, why would I be getting such a huge difference in oVirt?
