[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

Need VM run once api

This is a multipart message in MIME format. --=_alternative 00361B2065257E90_= Content-Type: text/plain; charset="US-ASCII" 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 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.

oVirt nVidia vGPU driver questions
by femi adegoke 17 Apr '19

17 Apr '19

I'm on oVirt 4.2.6. 1) If I have a Tesla P4 (Pascal) GPU (non-GRID), do I use nVidia vGPU driver for RHEL KVM 6.2 or the Linux KVM vGPU 6.2 driver? 2) If I have a Grid K1 or K2, I assume the correct driver would be GRID 4.7? 3) Must the vGPU driver be installed on the host & in the vm? 4) Must the vGPU driver be installed first before I can run "yum -y install vdsm-hook-vfio-mdev”

oVirt Node 4.3 Master on fc28
by femi adegoke 12 Apr '19

12 Apr '19

4.3 Master is looking good!! A few questions: - In Step #2: Fqdns: for a 3 host cluster, are we to add the 2nd & 3rd hosts? - In Step #5: Bricks: What effect does the RAID setting have? Enable Dedupe & Compression is new? Configure LV Cache: what do we enter for SSD? What happens if my disks are already all SSD, do I still benefit from using this?

Expand existing gluster storage in ovirt 4.2/4.3
by adrianquintero＠gmail.com 11 Apr '19

11 Apr '19

Hello, I have a 3 node ovirt 4.3 cluster that I've setup and using gluster (Hyperconverged setup) I need to increase the amount of storage and compute so I added a 4th host (server4.example.com) if it is possible to expand the amount of bricks (storage) in the "data" volume? I did some research and from that research the following caught my eye: old post "https://medium.com/@tumballi/scale-your-gluster-cluster-1-node-at-a-time-62…" So the question is, if taking that approach feasible? , is it even possible an oVirt point of view? --------------------------- My gluster volume: --------------------------- Volume Name: data Type: Replicate Volume ID: 003ffea0-b441-43cb-a38f-ccdf6ffb77f8 Status: Started Snapshot Count: 0 Number of Bricks: 1 x (2 + 1) = 3 Transport-type: tcp Bricks: Brick1: server1.example1.com:/gluster_bricks/data/data Brick2: server2.example.com:/gluster_bricks/data/data Brick3: server3.example.com:/gluster_bricks/data/data (arbiter) Options Reconfigured: cluster.granular-entry-heal: enable performance.strict-o-direct: on network.ping-timeout: 30 storage.owner-gid: 36 storage.owner-uid: 36 cluster.choose-local: off user.cifs: off features.shard: on cluster.shd-wait-qlength: 10000 cluster.shd-max-threads: 8 cluster.locking-scheme: granular cluster.data-self-heal-algorithm: full cluster.server-quorum-type: server cluster.quorum-type: auto cluster.eager-lock: enable network.remote-dio: enable performance.low-prio-threads: 32 performance.io-cache: off performance.read-ahead: off performance.quick-read: off transport.address-family: inet nfs.disable: on performance.client-io-threads: off Thanks.

Ovirt does not support AMD EPYC CPUs?
by Erick Perez 11 Apr '19

11 Apr '19

Hi, In its current release, OVIRT only shows AMD Opteron G1,G2,G3,G4,G5 and no mention of EPYC. This thread mentioned that a respin of Ovirt will address this, but never happened. https://lists.ovirt.org/archives/list/users@ovirt.org/message/2PEAYGK5PE33W… comments?
