Status of Snaphots and LVCache for VDO volumes in oVirt 4.3.x
by Guillaume Pavese 19 Feb '19

19 Feb '19

Hi, Currently choosing VDO at volume setup forces creation of a thick LV due to a RHEL bug, cf : https://bugzilla.redhat.com/show_bug.cgi?id=1634551 https://bugzilla.redhat.com/show_bug.cgi?id=1600156 The latter was closed while pointing to the following workaround : https://access.redhat.com/solutions/3562021 It is also said there that full fix will be available in RHEL-8 Thin LV are necessary to enable volume snapshots and LVCache, and are currently not possible on VDO volumes Does the above comments in BZs mean that it will still not be possible to configure Thin LV for VDO volumes with ovirt-4.3.x/Centos-7.X either? We have been postponing rolling out oVirt-4.2 in production because of these two major cons. Please advise if you think RHEL-8 will be necessary in order to have VDO volumes on par with normal volumes (snapshots and LVCache). In that case we will deploy production asap without VDO. Should we instead force the creation of VDO volmume on ThinLV by tweaking the gdeploy configuration and applying the mentionned workaround? Thanks Guillaume Pavese Ingénieur Système et Réseau Interactiv-Group

Re: Creating a static route
by Lev Veyde 18 Feb '19

18 Feb '19

Hi Doug, Sure, np. >> 1. - yes it is the priority setting of the specific rule. Basically you put in the file the post "ip rule add" part of the command e.g. for "ip rule add to 172.22.20.31 priority 32764" you need to put a line of "to 172.22.20.31 priority 32764" >> 2. - yes, the same priority can be used for all of them. E.g. if you want to route 172.22.20.31, 172.22.34.56 and 172.22.67.89 you will need to add: to 172.22.20.31 priority 32764 to 172.22.34.56 priority 32764 to 172.22.67.89 priority 32764 into the rule-<interface name> file e.g. rule-ovirtmgmt or rule-eno3. Please note that you will also need to add the static route for each one of these as well w/ "ip route add ... " command e.g. "ip route add 172.22.20.31 via 172.21.12.61". You can also use the route-<interface name> putting just the route info part, similar to the "ip rule" e.g. for equivalent of "ip route add 172.22.20.31 via 172.21.12.61" you need put in the file a line with the content "172.22.20.31 via 172.21.12.61". For routes it's important to use specifically the route-ovirtmgmt file since the script automatically adds the device to the route command i.e. you can put the following lines into your route-ovirtmgmt file: 172.22.20.31 via 172.21.12.61 172.22.34.56 via 172.21.12.61 172.22.67.89 via 172.21.12.68 (In case the first 2 of the mentioned IPs should be routed through the 172.21.12.61 gateway, and the last one should be routed through the 172.21.12.68 gateway). For the reference you can take a look at the /etc/sysconfig/network-scripts/ifup-routes script. It does the actual processing of both "route" and "rule" files for all network interfaces on a system. Please feel free to contact if you have further questions. Thanks in advance, On Thu, Feb 14, 2019 at 3:39 PM Doug Maxfield <Doug.L.Maxfield(a)emcins.com> wrote: > Lev, > > Thanks for the response.

After import storage many of my vm's disks not appear
by Kalil de A. Carvalho 18 Feb '19

18 Feb '19

Hello all. It is been a while that I used the oVirt and on the same time, the company where I started to work, has a big problem with the engine, we lose it. We did not have any backup. To try recovery the enverioment I installed a knew oVirt, this time Hosted Engine, and import the Storage. I could import and start some vm's but the most part not appear for me, dosen't show on "Disk Import", "VM Import" and any place. I know that is there, because show me that size. May I see, like list, this disks? I can't do this throught oVirt web. Is there any way to bring dist disks back?

SURVEY: your NFS configuration (Bug 1666795 - SHE doesn't start after power-off, 4.1 to 4.3 upgrade - VolumeDoesNotExist: Volume does not exist )
by Nir Soffer 18 Feb '19

18 Feb '19

Looking at https://bugzilla.redhat.com/1666795 It seems that a change in vdsm/libvirt exposed NFS configuration issue, that may was needed in the past and probably not needed now. If you use NFS, I would like to see your /etc/exports (after sanitizing it if needed). For extra bonus, output of "exportfs -v" would be useful. In particular, I want to know if you use root_squash, all_squash, or no_root_squash. Thanks, Nir

How to set hot plugged memory online_movable
by zodaoko＠gmail.com 18 Feb '19

18 Feb '19

Hi, I'd like to try the memory hot unplug, refer to: https://www.ovirt.org/documentation/vmm-guide/chap-Editing_Virtual_Machines…: "All blocks of the hot-plugged memory must be set to **online_movable** in the virtual machine’s device management rules. In virtual machines running up-to-date versions of Enterprise Linux or CoreOS, this rule is set by default." I created a VM running CentOS7.6: # more /etc/redhat-release CentOS Linux release 7.6.1810 (Core) # more /usr/lib/udev/rules.d/40-redhat.rules ... # Memory hotadd request SUBSYSTEM!="memory", ACTION!="add", GOTO="memory_hotplug_end" PROGRAM="/bin/uname -p", RESULT=="s390*", GOTO="memory_hotplug_end" ENV{.state}="online" PROGRAM="/bin/systemd-detect-virt", RESULT=="none", ENV{.state}="online_movable" ATTR{state}=="offline", ATTR{state}="$env{.state}" LABEL="memory_hotplug_end" It looks like the online_movable will be set only when systemd-detect-virt returns none, i.e. hot plugging memory for a bare-metal machine, so how to make the hot plugged memory "online_movable" in the virtual machines? Thank you. Regards, -Zhen

changes in oVirt 4.3 and vGPU?
by Hetz Ben Hamo 18 Feb '19

18 Feb '19

Hi, I just installed a Tesla T4 card, installed the nvidia's RPM, I see the mdev_type stuff etc. Following their instructions, I'm trying to set a Windows 10 VM to use the vGPU (the VM works without any vGPU), I get this error in the event... VM Win-10-test is down with error. Exit message: internal error: qemu unexpectedly closed the monitor: 2019-02-08T14:01:11.287955Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config, ability to start up with partial NUMA mappings is obsoleted and will be removed in future 2019-02-08T14:01:11.313878Z qemu-kvm: -device vfio-pci,id=hostdev0,sysfsdev=/sys/bus/mdev/devices/486b48a3-01c7-4a67-9727-279813bae0e8,display=off,bus=pci.0,addr=0x8: vfio error: 486b48a3-01c7-4a67-9727-279813bae0e8: error getting device from group 0: Input/output error Verify all devices in group 0 are bound to vfio-<bus> or pci-stub and not already in use. Could someone explain to me what am I missing and what to do? I don't see any docs about it. Thanks

Migration of VMs across two Ovirt setups
by ddc.comp＠gmail.com 18 Feb '19

18 Feb '19

Hi, I have two ovirt setups having multiple hosts and cluster and around 100+ vms in one and around 32 in one setup. I want to dismantle one setup and before before doing so all vms are need to be migrated to one setup I tried with import vms from another setup using Libvert -- https://ovirt.org/develop/release-management/features/virt/KvmToOvirt.html but no luck connection not getting established. What if I simply remove one host from one setup having local storage(all vms are located on local storage) and simply add it to another setup? and then migrate VMs from local to shared storage and then dismantle host ! Regards Dipak Chaudhari

AMD EPYC 4.3 upgrade 'CPU type is not supported in this cluster compatibility version or is not supported at all'
by Ryan Bullock 18 Feb '19

18 Feb '19

We just updated our engine to 4.3, but when I tried to update one of our AMD EPYC hosts it could not activate with the error: Host vmc2h2 moved to Non-Operational state as host CPU type is not supported in this cluster compatibility version or is not supported at all. Relevant (I think) parts from the the engine log: (EE-ManagedThreadFactory-engineScheduled-Thread-82) [ee51a70] Could not find server cpu for server 'vmc2h2' (745a14c6-9d31-48a4-9566-914647d83f53), flags: 'fpu,vme,de,pse,tsc,msr,pae,mce,cx8,apic,sep,mtrr,pge,mca,cmov,pat,pse36,clflush,mmx,fxsr,sse,sse2,ht,syscall,nx,mmxext,fxsr_opt,pdpe1gb,rdtscp,lm,constant_tsc,art,rep_good,nopl,nonstop_tsc,extd_apicid,amd_dcm,aperfmperf,eagerfpu,pni,pclmulqdq,monitor,ssse3,fma,cx16,sse4_1,sse4_2,movbe,popcnt,aes,xsave,avx,f16c,rdrand,lahf_lm,cmp_legacy,svm,extapic,cr8_legacy,abm,sse4a,misalignsse,3dnowprefetch,osvw,skinit,wdt,tce,topoext,perfctr_core,perfctr_nb,bpext,perfctr_l2,cpb,hw_pstate,sme,retpoline_amd,ssbd,ibpb,vmmcall,fsgsbase,bmi1,avx2,smep,bmi2,rdseed,adx,smap,clflushopt,sha_ni,xsaveopt,xsavec,xgetbv1,clzero,irperf,xsaveerptr,arat,npt,lbrv,svm_lock,nrip_save,tsc_scale,vmcb_clean,flushbyasid,decodeassists,pausefilter,pfthreshold,avic,v_vmsave_vmload,vgif,overflow_recov,succor,smca' 2019-02-06 17:23:58,527-08 INFO [org.ovirt.engine.core.vdsbroker.SetVdsStatusVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-82) [7f6d4f0d] START, SetVdsStatusVDSCommand(HostName = vmc2h2, SetVdsStatusVDSCommandParameters:{hostId='745a14c6-9d31-48a4-9566-914647d83f53', status='NonOperational', nonOperationalReason='CPU_TYPE_INCOMPATIBLE_WITH_CLUSTER' From virsh -r capabilities: <cpu> <arch>x86_64</arch> <model>EPYC-IBPB</model> <vendor>AMD</vendor> <microcode version='134222375'/> <topology sockets='1' cores='32' threads='2'/> <feature name='ht'/> <feature name='osxsave'/> <feature name='xsaves'/> <feature name='cmp_legacy'/> <feature name='extapic'/> <feature name='skinit'/> <feature name='wdt'/> <feature name='tce'/> <feature name='topoext'/> <feature name='perfctr_core'/> <feature name='perfctr_nb'/> <feature name='invtsc'/> <pages unit='KiB' size='4'/> <pages unit='KiB' size='2048'/> <pages unit='KiB' size='1048576'/> </cpu> I also tried creating a new 4.3 cluster, set to the AMD EPYC IPBDB SSBD and moving the host into it, but it failed to move it into that cluster with a similar error about an unsupported CPU (for some reason it also made me clear the additional kernel options as well, we use 1gb hugepages). I have not yet tried removing the host entirely and adding it as part of creating the new cluster. We have been/are using a database change to update the 4.2 cluster level to include EPYC support with the following entries (can post the whole query if needed): 7:AMD EPYC:svm,nx,model_EPYC:EPYC:x86_64; 8:AMD EPYC IBPB:svm,nx,ibpb,model_EPYC:EPYC-IBPB:x86_64 We have been running 4.2 with this for awhile. We did apply the same changes after the 4.3 update, but only for the 4.2 cluster level. We only used the AMD EPYC IBPB model. Reverting the host back to 4.2 allows it to activate and run normally. Anyone have any ideas as to why it can't seem to find the cpu type? Thanks, Ryan Bullock

new easy way to open issues for ovirt.org and documentation
by Greg Sheremeta 18 Feb '19

18 Feb '19

Hi, I created some footer links on ovirt.org to make it super easy to open GitHub issues. We often get questions about where to report documentation issues and things like that -- hopefully this eases the pain. When you are visiting any page on ovirt.org and you see a problem or have an idea for enhancement, simply scroll down and click 'Report an issue on GitHub'. [image: Selection_393.png] Full demo (2 minutes): https://www.youtube.com/watch?v=TbORKknLVL4 (and, of course, if you're so inclined, the Edit link starts a PR for you ...)

Huge Pages
by Vincent Royer 17 Feb '19

17 Feb '19

How do I know how many huge pages my hosts can support? cat /proc/meminfo | grep Huge AnonHugePages: 17684480 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB [image: image.png] And once I know, I set the kernel parameters here, and reboot the host, correct? [image: image.png] And then I assume I assign them to the VM here? How do I decide how many huge pages and what size a particular VM can benefit from? [image: image.png] Is there a part of the docs I am not finding that covers this?

Re: Ovirt Cluster completely unstable

Just thinking....

oVirt upgrade to specific version
by Leo David 16 Feb '19

16 Feb '19

Hi, I have a running 4.2.7 hci cluster which I would upgrade to 4.2.8. If I do this in the standard manner (yum update in engine vm and then the nodes from engine UI) I assume it will go to 4.3, which I would rather avoid for now. Is there a way for getting it updated strictelly to 4.2.8 ? Thanks, Leo

Ovirt Cluster completely unstable

I'm abandoning my production ovirt cluster due to instability. I have a 7 host cluster running about 300 vms and have been for over a year. It has become unstable over the past three days. I have random hosts both, compute and storage disconnecting. AND many vms disconnecting and becoming unusable. 7 host are 4 compute hosts running Ovirt 4.2.8 and three glusterfs hosts running 3.12.5. I submitted a bugzilla bug and they immediately assigned it to the storage people but have not responded with any meaningful information. I have submitted several logs. I have found some discussion on problems with instability with gluster 3.12.5. I would be willing to upgrade my gluster to a more stable version if that's the culprit. I installed gluster using the ovirt gui and this is the version the ovirt gui installed. Is there an ovirt health monitor available? Where should I be looking to get a resolution the problems I'm facing.

Upgrade from 4.2.7 to 4.3.0 troubles
by mariani.alberto＠libero.it 15 Feb '19

15 Feb '19

Hello All, I'm trying to upgrade a Self Hosted Engine installation from 4.2.7 to 4.3.0. I was able to update the Engine itself, but when I try the general update for both the Engine VM and the Self Hosted Nodes the update fails because the openvswitch-ovn-* packages want a long series of libraries as dependencies, all with the name librte_* Unfortunately, I don't think these exist in CentOs 7, so I'm having no luck in finding them. Am I doing something wrong? Best Regards, Alberto M.
