VMs import over slow 1gig interface instead of fast 10gig interface?
by Jacob Green 13 May '19

13 May '19

Ok, so I want to try and more thoroughly explain my situation. I want to better understand what is happening, and if there is a way to force import over the faster connection. Today I have two Ovirt environments, one on 4.1 and one on 4.2, on the new environment we have migrated to new VLANs for Management and Data. The export domain is a NFS domain hosted on a Trunas device that has an ip address of X.X.12.100. Our host has multiple Ethernet connections, one Bonded 20Gigabit interface. That is where we have the ovirtmgmt profile. And a secondary 1 Gigabit interface that we call our VLAN12 profile or server VLAN. *The problem.... *When importing a VM from the export domain, the import is happening over the 1Gigabit interface on the VLAN12 profile. Instead of the 20gigabit Bonded interface on VLAN 100. *My understanding.... *So I probably just misunderstand how this works, but here is what I thought should happen, in the *Setup Host Network* screen for this host I have the ovirtmgmt on VLAN100 with the bonded 20Gigabit interface performing the following. "*Management, Display, Migration, VM and Default Route*." Then I have the secondary 1 Gigabit interface just doing "*VM*" on VLAN12. What I thought should happen is that anything Migration related "*/Includes importing from export domain?/*" should happen on the Migration interface, which in my case is the ovritmgmt interface on VLAN100. I have also confirmed that I can ping from the VLAN100 ovirtmgmt interface to the storage on VLAN12. So there is connectivity from that interface to the storage. What I am trying to figure out is there a way to force it to do imports over the 20Gigabit interface that resides on VLAN100 instead of the slower VLAN12 interface, that is just there for general VM connectivity. Thank you for any advice or guidance on this matter. -- Jacob Green Systems Admin American Alloy Steel

[Users] Lifecycle / upgradepath
by Sven Kieske 11 May '19

11 May '19

Hi Community, Currently, there is no single document describing supported (which means: working ) upgrade scenarios. I think the project has matured enough, to have such an supported upgradepath, which should be considered in the development of new releases. As far as I know, currently it is supported to upgrade from x.y.z to x.y.z+1 and from x.y.z to x.y+1.z but not from x.y-1.z to x.y+1.z directly. maybe this should be put together in a wiki page at least. also it would be cool to know how long a single "release" would be supported. In this context I would define a release as a version bump from x.y.z to x.y+1.z or to x+1.y.z a bump in z would be a bugfix release. The question is, how long will we get bugfix releases for a given version? What are your thoughts? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Users] Nested virtualization with Opteron 2nd generation and oVirt 3.1 possible?
by Gianluca Cecchi 11 May '19

11 May '19

Hello, I have 2 physical servers with Opteron 2nd gen cpu. There is CentOS 6.3 installed and some VM already configured on them. Their /proc/cpuinfo contains ... model name : Dual-Core AMD Opteron(tm) Processor 8222 ... kvm_amd kernel module is loaded with its default enabled nested option # systool -m kvm_amd -v Module = "kvm_amd" Attributes: initstate = "live" refcnt = "15" srcversion = "43D8067144E7D8B0D53D46E" Parameters: nested = "1" npt = "1" ... I already configured a fedora 17 VM as a oVirt 3.1 Engine I'm trying to configure another VM as oVirt 3.1 node with ovirt-node-iso-2.5.5-0.1.fc17.iso It seems I'm not able to configure so that ovirt install doesn't complain. After some attempts, I tried this in my vm.xml for the cpu: <cpu mode='custom' match='exact'> <model fallback='allow'>athlon</model> <vendor>AMD</vendor> <feature policy='require' name='pni'/> <feature policy='require' name='rdtscp'/> <feature policy='force' name='svm'/> <feature policy='require' name='clflush'/> <feature policy='require' name='syscall'/> <feature policy='require' name='lm'/> <feature policy='require' name='cr8legacy'/> <feature policy='require' name='ht'/> <feature policy='require' name='lahf_lm'/> <feature policy='require' name='fxsr_opt'/> <feature policy='require' name='cx16'/> <feature policy='require' name='extapic'/> <feature policy='require' name='mca'/> <feature policy='require' name='cmp_legacy'/> </cpu> Inside node /proc/cpuinfo becomes processor : 3 vendor_id : AuthenticAMD cpu family : 6 model : 2 model name : QEMU Virtual CPU version 0.12.1 stepping : 3 microcode : 0x1000065 cpu MHz : 3013.706 cache size : 512 KB fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall mmxext fxsr_opt lm nopl pni cx16 hypervisor lahf_lm cmp_legacy cr8_legacy bogomips : 6027.41 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: 2 questions: 1) Is there any combination in xml file to give to my VM so that oVirt doesn't complain about missing hardware virtualization with this processor? 2) suppose 1) is not possible in my case and I still want to test the interface and try some config operations to see for example the differences with RHEV 3.0, how can I do? At the moment this complaint about hw virtualization prevents me to activate the node. I get Installing Host f17ovn01. Step: RHEV_INSTALL. Host f17ovn01 was successfully approved. Host f17ovn01 running without virtualization hardware acceleration Detected new Host f17ovn01. Host state was set to Non Operational. Host f17ovn01 moved to Non-Operational state. Host f17ovn01 moved to Non-Operational state as host does not meet the cluster's minimum CPU level. Missing CPU features : CpuFlags Can I lower the requirements to be able to operate without hw virtualization in 3.1? Thanks in advance, Gianluca

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.

Ovirt Nested in VMWare (Working approach)
by RabidCicada 30 Apr '19

30 Apr '19

I worked through this previously and posted in IRC yesterday about working around running ovirt nested under VMWare. I figured i'd post it to the mail group so that it would be available in it's entirety here for future reference: The following gists explain the 3 major adjustments that have to be made currently to get nested virt under vmware working: https://gist.github.com/RabidCicada/993349b3a7eaf35637122f0122fdedb3 https://gist.github.com/RabidCicada/bc01eb0b13195faa26520c0fb666ec34 https://gist.github.com/RabidCicada/37ff6f1ed2afd8dd4edefac735536c69 https://gist.github.com/RabidCicada/40655db1582ca5d07c9bbf2c429cdd01 Hopefully it can save others the huge amount of time it took me to figure it all out. Specifically it's a problem with the --machine type at 3 major parts of the vm creation for the hosted-engine. 1) You have to fix the virt-install to use --machine pc-i440fx-rhel7.2.0 2) You have to fix the guestfish spinup of the partially configured vm to use --machine pc-i440fx-rhel7.2.0, where they edit the nic config among other things 3) You have to tell vdsm on the node to use --machine pc-i440fx-rhel7.2.0 I don't know the underlying reason why a --machine type > pc-i440fx-rhel7.2.0 breaks the system but it ends up resulting in a bios freeze. Again, Hope this helps someone. Suggested only to use for a test/dev system.

Upgraded ovirt-4.2 to ovirt-4.3 and VM run fails
by Gobinda Das 29 Apr '19

29 Apr '19

Hi, I have upgraded ovirt-4.2 to ovirt-4.3 and after upgrade while starting vms giving me error: Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details: The host *node1.test.com <http://node1.test.com>* did not satisfy internal filter ClusterInMaintenance because the cluster is in maintenance and only highly available VMs are allowed to start. The host *node2.test.com <http://node2.test.com>* did not satisfy internal filter ClusterInMaintenance because the cluster is in maintenance and only highly available VMs are allowed to start. The host *node3.test.com <http://node3.test.com>* did not satisfy internal filter ClusterInMaintenance because the cluster is in maintenance and only highly available VMs are allowed to start. Eventhough cluster is not in maintenance mode. This setup is using gluster6 for storage. -- Thanks, Gobinda
