unable to update to 4.0
by Jeb Baxley 30 Aug '16

30 Aug '16

Hi All, I have Ovirt 3.6.7 installed and running. However, when attempting to update to 4.0 I receive this error when running engine-setup. Failed to execute stage 'Setup validation': Trying to upgrade from unsupported versions: 3.5 I find this pretty strange as I haven't run 3.5 in a long time and can confirm that I'm running 3.6.7.

VM Live Migration issues
by Anantha Raghava 29 Aug '16

29 Aug '16

Hi, In our setup we have configured two hosts, both of same CPU type, same amount of memory and Master storage domain is created on iSCSI storage and is live. I created a single VM with Ubuntu Trusty as OS. It installed properly and when I attempted to migrate the running VM, the migration failed. Engine log, Host 1 log and Host 2 logs are attached for your reference. Since logs are running into several MBs, I have compressed them and attached here. Can someone help us to solve this issue? -- Thanks & Regards, Anantha Raghava

how to debug no audio in guest?
by Gianluca Cecchi 29 Aug '16

29 Aug '16

Hello, I'm testing video and audio capacity inside a guest. Guest chosen is CentOS 6 with latest updates. oVirt is 3.6.6 on an intel NUC6i5SYH with CentOS 7.2 OS BTW: is it of any importance audio adapter on the host? In case lspci on host gives 00:1f.3 Audio device: Intel Corporation Device 9d70 (rev 21) Client connecting from user portal is Fedora 23 on an Asus laptop U36SD where audio works and lspci gives 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) On CentOS 6 guest the audio adapter detected by OS with lspci is 00:08.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 01) It seems all ok, apart that on guest actually I don't get any audio, also from test speakers page ;-) Both on guest and on client the volume bar is near the maximum. Any hints about debugging? >From host point of view the qemu-kvm command line is this one below I don't understand the env variable QEMU_AUDIO_DRV=none ??? If it can be of any importance, I initially configured the guest without sound card and in fact in gnome I saw the audio card as "dummy". Then I powered off the guest and enabled sound card from user portal edit vm (I see it enabled also from admin portal btw...) and then powered on the VM. Now the sound card seems to be present but no audio Thanks in advance, Gianluca 2016-06-11 09:22:13.698+0000: starting up libvirt version: 1.2.17, package: 13.el7_2.4 (CentOS BuildSystem <http://bugs.centos.org>, 2016-03- 31-16:56:26, worker1.bsys.centos.org) qemu version: 2.3.0 (qemu-kvm-ev-2.3.0-31.el7_2.10.1) LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin QEMU_AUDIO_DRV=none /usr/libexec/qemu-kvm -name c6desktop -S -machine pc-i440 fx-rhel7.2.0,accel=kvm,usb=off -cpu Broadwell-noTSX -m size=3145728k,slots=16,maxmem=4294967296k -realtime mlock=off -smp 1,maxcpus=16,socket s=16,cores=1,threads=1 -numa node,nodeid=0,cpus=0,mem=3072 -uuid 68a82ada-a1d2-44d0-85b0-f3a08cc2f579 -smbios type=1,manufacturer=oVirt,produ ct=oVirt Node,version=7-2.1511.el7.centos.2.10,serial=AC1EDDD3-CAF1-2711-EE16-B8AEED7F1711,uuid=68a82ada-a1d2-44d0-85b0-f3a08cc2f579 -no-user -config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/domain-c6desktop/monitor.sock,server,nowait -mon chardev=charmo nitor,id=monitor,mode=control -rtc base=2016-06-11T09:22:13,driftfix=slew -global kvm-pit.lost_tick_policy=discard -no-hpet -no-shutdown -boo t menu=on,strict=on -device ich9-usb-ehci1,id=usb,bus=pci.0,addr=0x9.0x7 -device ich9-usb-uhci3,masterbus=usb.0,firstport=4,bus=pci.0,addr=0x 9.0x2 -device ich9-usb-uhci2,masterbus=usb.0,firstport=2,bus=pci.0,addr=0x9.0x1 -device ich9-usb-uhci1,masterbus=usb.0,firstport=0,bus=pci.0, multifunction=on,addr=0x9 -device virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x3 -device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pc i.0,addr=0x4 -drive if=none,id=drive-ide0-1-0,readonly=on,format=raw -device ide-cd,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -drive file=/rhev/data-center/00000001-0001-0001-0001-000000000343/572eabe7-15d0-42c2-8fa9-0bd773e22e2e/images/aff55e62-6a41-4f75-bbd3-78561eae18f3/ f520473e-8fbe-4886-bb64-921b42edf499,if=none,id=drive-virtio-disk0,format=raw,serial=aff55e62-6a41-4f75-bbd3-78561eae18f3,cache=none,werror=s top,rerror=stop,aio=threads -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x5,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev t ap,fd=28,id=hostnet0,vhost=on,vhostfd=29 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:1a:4a:16:01:51,bus=pci.0,addr=0x7 -chardev soc ket,id=charserial0,path=/var/run/ovirt-vmconsole-console/68a82ada-a1d2-44d0-85b0-f3a08cc2f579.soc k,server,nowait -device isa-serial,chardev=charserial0,id=serial0 -chardev socket,id=charchannel0,path=/var/lib/libvirt/qemu/channels/68a82ada-a1d2-44d0-85b0-f3a08cc2f579.com.redhat.rhevm.vdsm,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.rhevm.vdsm -chardev socket,id=charchannel1,path=/var/lib/libvirt/qemu/channels/68a82ada-a1d2-44d0-85b0-f3a08cc2f579.org.qemu.guest_agent.0,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=2,chardev=charchannel1,id=channel1,name=org.qemu.guest_agent.0 -chardev spicevmc,id=charchannel2,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=3,chardev=charchannel2,id=channel2,name=com.redhat.spice.0 -spice port=5901,tls-port=5902,addr=0,x509-dir=/etc/pki/vdsm/libvirt-spice,seamless-migration=on -vnc 0:3,password -device qxl-vga,id=video0,ram_size=67108864,vram_size=8388608,vgamem_mb=16,bus=pci.0,addr=0x2 -device intel-hda,id=sound0,bus=pci.0,addr=0x8 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -chardev spicevmc,id=charredir0,name=usbredir -device usb-redir,chardev=charredir0,id=redir0 -chardev spicevmc,id=charredir1,name=usbredir -device usb-redir,chardev=charredir1,id=redir1 -chardev spicevmc,id=charredir2,name=usbredir -device usb-redir,chardev=charredir2,id=redir2 -chardev spicevmc,id=charredir3,name=usbredir -device usb-redir,chardev=charredir3,id=redir3 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x6 -msg timestamp=on 2016-06-11T09:22:13.748410Z qemu-kvm: warning: CPU(s) not present in any NUMA nodes: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 2016-06-11T09:22:13.748524Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config main_channel_link: add main channel client main_channel_handle_parsed: net test: latency 21.910000 ms, bitrate 51635025 bps (49.242997 Mbps) inputs_connect: inputs channel client create red_dispatcher_set_cursor_peer: main_channel_handle_parsed: agent start main_channel_handle_parsed: agent start

Hosted engine on gluster problem
by Bond, Darryl 29 Aug '16

29 Aug '16

There seems to be a pretty severe bug with using hosted engine on gluster. If the host that was used as the initial hosted-engine --deploy host goes away, the engine VM wil crash and cannot be restarted until the host comes back. This is regardless of which host the engine was currently running. The issue seems to be buried in the bowels of VDSM and is not an issue with gluster itself. The gluster filesystem is still accessable from the host that was running the engine. The issue has been submitted to bugzilla but the fix is some way off (4.1). Can my hosted engine be converted to use NFS (using the gluster NFS server on the same filesystem) without rebuilding my hosted engine (ie change domainType=glusterfs to domainType=nfs)? What effect would that have on the hosted-engine storage domain inside oVirt, ie would the same filesystem be mounted twice or would it just break. Will this actually fix the problem, does it have the same issue when the hosted engine is on NFS?

How to manually restore backup
by Hanson 29 Aug '16

29 Aug '16

Hi Guys, Just wondering what the proper way to restore a backup to a hosted-engine? I've tried doing the deploy, then cleanup, and backup --mode=restore, but then engine-setup needs internet access. (which it doesn't have) Is there a way to restore the backup over the current data of a currently deployed new host? ie like a --mode=restore --option=force ? or is there another way to restore? Thanks, Hanson

Hi, Did you try to remove the Host and reinstall it, can you please attach the engine and VDSM logs. I found an email which might help if that is indeed the same issue: http://lists.ovirt.org/pipermail/users/2014-November/028870.html Regards, Maor On Mon, Aug 29, 2016 at 12:47 PM, 554450306(a)qq.com <554450306(a)qq.com> wrote: > hi，all: > now ,I deploy a ovirt enviroment ,the ovirt enviroment include two nodes, > the system is centos 7.0,now when I add a node to the engine,find a error : > can you help me? > ------------------------------ > 554450306(a)qq.com > > _______________________________________________ > Users mailing list > Users(a)ovirt.org > http://lists.ovirt.org/mailman/listinfo/users > >

I would upgrade my CentOS 6.8 to 7 on my cluster of 5 ovirt nodes (actually I'm running oVirt 3.5 and glusterfs 3.7). Anyone has experienced troubles for this upgrade? Thank you, Fedele

iSCSI Multipathing -> host inactive
by Uwe Laverenz 29 Aug '16

29 Aug '16

Hi all, I'd like to test iSCSI multipathing with OVirt 4.02 and see the following problem: if I try to add an iSCSI-Bond the host loses connection to _all_ storage domains. I guess I'm doing something wrong. :) I have built a small test environment for this: The storage is provided by a freenas box with two dedicated interfaces for two separate iSCSI networks. Each interface has one address in one network (no VLANs, no trunking). For each network there is one portal configured. Both portals point to the same target. The target has 4 LUNs. The host also has two dedicated interfaces for iSCSI and finds the target over both portals, all LUNs are selected for use and show 2 paths. My questions: 1) Is this setup ok or did I miss something? 2) The LUNs already show 2 paths (multipath -ll), one "active" and one "enabled", what difference would a Datacenter iSCSI-bond make? 3) What combination of checkboxes do I have to use? Logical Letworks [ ] ISCSIA [ ] ISCSIB Storage Targets [ ] iqn.2005-10.org.freenas.ctl:tgt01 10.0.131.121 3260 [ ] iqn.2005-10.org.freenas.ctl:tgt01 10.0.132.121 3260 As stated in the beginning: all my tests made the host lose connection to all storage domains (NFS included) and I can not see what I am doing wrong. Thank you very much! cu, Uwe
