[Users] After upgrade of ovirt > 3.3 all Windows vms lost their activation against Microsoft
by Ricky Schneberger 25 Feb '14

25 Feb '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Why is the Windows VMs always lost their activation against Microsoft after that I have upgrade ovirt? Is there så big changes in hardware drivers etc that it will hit the activation mechanism? I think there should be a way to preserve the activation even after an upgrade. regards - -- Ricky Schneberger -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlMLA7wACgkQOap81biMC2MTUQCbBEkMwhuWuCEAHuj7YT1vTQ/F Kg8An1+5n1SgIFG4KS/9vRkqng9VGyp9 =/Xos -----END PGP SIGNATURE-----

[Users] Installing hosted-engine on centos
by Andy Michielsen 25 Feb '14

25 Feb '14

Hello all, I'm trying to install a self hosted engine on my Centos 6.5 server but as I try to do yum install ovirt-hosted-engine-setup I get the message that it can not find the package. I already added these repositories. yum install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm yum install http://resources.ovirt.org/releases/ovirt-engine-el.noarch.rpm What am I missing here ? Kind regards.

[Users] Opinions needed: 3 node gluster replica 3 | NFS async | snapshots for consistency
by Steve Dainard 25 Feb '14

25 Feb '14

I'm looking for some opinions on this configuration in an effort to increase write performance: 3 storage nodes using glusterfs in replica 3, quorum. Ovirt storage domain via NFS Volume set nfs.trusted-sync on On Ovirt, taking snapshots often enough to recover from a storage crash Using CTDB to manage NFS storage domain IP, moving it to another storage node when necessary Something along the lines of EC2's data consistency model, where only snapshots can be considered reliable. The Ovirt added advantage would be memory consistency at time of snapshot as well. Feedback appreciated, including 'you are insane for thinking this is a good idea' (and some supported reasoning would be great).

Hi all, Interesting thing I found out this afternoon. I have a FreeBSD 10 guest with virtio drivers, both disk and net. The VM works fine, but when I connect over SSH to the VM, I see this stack trace in messages on the node: Feb 23 19:19:42 hv3 kernel: ------------[ cut here ]------------ Feb 23 19:19:42 hv3 kernel: WARNING: at net/core/dev.c:1907 skb_warn_bad_offload+0xc2/0xf0() (Tainted: G W --------------- ) Feb 23 19:19:42 hv3 kernel: Hardware name: X9DR3-F Feb 23 19:19:42 hv3 kernel: igb: caps=(0x12114bb3, 0x0) len=5686 data_len=5620 ip_summed=0 Feb 23 19:19:42 hv3 kernel: Modules linked in: ebt_arp nfs lockd fscache auth_rpcgss nfs_acl sunrpc bonding 8021q garp ebtable_nat ebtables bridge stp llc xt_physdev ipt_REJECT nf_conntrack_ipv4 nf_defrag_ipv4 xt_multiport iptable_filter ip_tables ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables ipv6 dm_round_robin dm_multipath vhost_net macvtap macvlan tun kvm_intel kvm iTCO_wdt iTCO_vendor_support sg ixgbe mdio sb_edac edac_core lpc_ich mfd_core i2c_i801 ioatdma igb dca i2c_algo_bit i2c_core ptp pps_core ext4 jbd2 mbcache sd_mod crc_t10dif 3w_sas ahci isci libsas scsi_transport_sas dm_mirror dm_region_hash dm_log dm_mod [last unloaded: scsi_wait_scan] Feb 23 19:19:42 hv3 kernel: Pid: 15280, comm: vhost-15276 Tainted: G W --------------- 2.6.32-431.5.1.el6.x86_64 #1 Feb 23 19:19:42 hv3 kernel: Call Trace: Feb 23 19:19:42 hv3 kernel: <IRQ> [<ffffffff81071e27>] ? warn_slowpath_common+0x87/0xc0 Feb 23 19:19:42 hv3 kernel: [<ffffffff81071f16>] ? warn_slowpath_fmt+0x46/0x50 Feb 23 19:19:42 hv3 kernel: [<ffffffffa016c862>] ? igb_get_drvinfo+0x82/0xe0 [igb] Feb 23 19:19:42 hv3 kernel: [<ffffffff8145b1d2>] ? skb_warn_bad_offload+0xc2/0xf0 Feb 23 19:19:42 hv3 kernel: [<ffffffff814602c1>] ? __skb_gso_segment+0x71/0xc0 Feb 23 19:19:42 hv3 kernel: [<ffffffff81460323>] ? skb_gso_segment+0x13/0x20 Feb 23 19:19:42 hv3 kernel: [<ffffffff814603cb>] ? dev_hard_start_xmit+0x9b/0x480 Feb 23 19:19:42 hv3 kernel: [<ffffffff8147bf5a>] ? sch_direct_xmit+0x15a/0x1c0 Feb 23 19:19:42 hv3 kernel: [<ffffffff81460a58>] ? dev_queue_xmit+0x228/0x320 Feb 23 19:19:42 hv3 kernel: [<ffffffffa035a898>] ? br_dev_queue_push_xmit+0x88/0xc0 [bridge] Feb 23 19:19:42 hv3 kernel: [<ffffffffa035a928>] ? br_forward_finish+0x58/0x60 [bridge] Feb 23 19:19:42 hv3 kernel: [<ffffffffa035a9da>] ? __br_forward+0xaa/0xd0 [bridge] Feb 23 19:19:42 hv3 kernel: [<ffffffff814897b6>] ? nf_hook_slow+0x76/0x120 Feb 23 19:19:42 hv3 kernel: [<ffffffffa035aa5d>] ? br_forward+0x5d/0x70 [bridge] Feb 23 19:19:42 hv3 kernel: [<ffffffffa035ba6b>] ? br_handle_frame_finish+0x17b/0x2a0 [bridge] Feb 23 19:19:42 hv3 kernel: [<ffffffffa035bd3a>] ? br_handle_frame+0x1aa/0x250 [bridge] Feb 23 19:19:42 hv3 kernel: [<ffffffff8145b7c9>] ? __netif_receive_skb+0x529/0x750 Feb 23 19:19:42 hv3 kernel: [<ffffffff8145ba8a>] ? process_backlog+0x9a/0x100 Feb 23 19:19:42 hv3 kernel: [<ffffffff81460d43>] ? net_rx_action+0x103/0x2f0 Feb 23 19:19:42 hv3 kernel: [<ffffffff8107a8e1>] ? __do_softirq+0xc1/0x1e0 Feb 23 19:19:42 hv3 kernel: [<ffffffff8100c30c>] ? call_softirq+0x1c/0x30 Feb 23 19:19:42 hv3 kernel: <EOI> [<ffffffff8100fa75>] ? do_softirq+0x65/0xa0 Feb 23 19:19:42 hv3 kernel: [<ffffffff814611c8>] ? netif_rx_ni+0x28/0x30 Feb 23 19:19:42 hv3 kernel: [<ffffffffa01a0749>] ? tun_sendmsg+0x229/0x4ec [tun] Feb 23 19:19:42 hv3 kernel: [<ffffffffa027bcf5>] ? handle_tx+0x275/0x5e0 [vhost_net] Feb 23 19:19:42 hv3 kernel: [<ffffffffa027c095>] ? handle_tx_kick+0x15/0x20 [vhost_net] Feb 23 19:19:42 hv3 kernel: [<ffffffffa027955c>] ? vhost_worker+0xbc/0x140 [vhost_net] Feb 23 19:19:42 hv3 kernel: [<ffffffffa02794a0>] ? vhost_worker+0x0/0x140 [vhost_net] Feb 23 19:19:42 hv3 kernel: [<ffffffff8109aee6>] ? kthread+0x96/0xa0 Feb 23 19:19:42 hv3 kernel: [<ffffffff8100c20a>] ? child_rip+0xa/0x20 Feb 23 19:19:42 hv3 kernel: [<ffffffff8109ae50>] ? kthread+0x0/0xa0 Feb 23 19:19:42 hv3 kernel: [<ffffffff8100c200>] ? child_rip+0x0/0x20 Feb 23 19:19:42 hv3 kernel: ---[ end trace e93142595d6ecfc7 ]--- This is 100% reproducable, every time.

[Users] Vm's being paused
by Neil 24 Feb '14

24 Feb '14

Hi guys, I've had two different Vm's randomly pause this past week and inside ovirt the error received is something like 'vm ran out of storage and was paused'. Resuming the vm's didn't work and I had to force them off and then on which resolved the issue. Has anyone had this issue before? I realise this is very vague so if you could please let me know which logs to send in. Thank you Regards. Neil Wilson

[Users] Setting up a test enviroment
by Andy Michielsen 24 Feb '14

24 Feb '14

Hello, I 'm starting to set up an ovirt enviroment to provide our test users a free but decent setup. I have two servers and I would like to use one for NFS storage because of the availability of 1 Tb and the the other server only as a node. I'm not sure where to install the ovirt-engine on. The NFS server has two quadcores and 32 Gb of RAM and 6 NIC's The Node has two sixcores and 64 Gb of RAM and only 2 NIC's Kind regards.

Hey Guys, I'm back ;-). This time I have a question from one of our programmers. He's trying this: http://www.ovirt.org/How_to_Connect_to_SPICE_Console_Without_Portal#Connect… But he bumps into this: Connect to the client again (again, r-v will ask for the password in a pop-up window): bash$ *remote-viewer --spice-ca-file ${CA_FILE} --spice-host-subject "${SUBJECT}" spice://${HOST}/?port=${PORT}\&tls-port=${SPORT}* Now, the question is.... What's the password? Or where can I find it? Kind regards, Koen

[Users] "Last Updated" shows current time instead of last update
by Yedidyah Bar David 23 Feb '14

23 Feb '14

Hi all, Sorry for cross-posting. Not sure what's the correct address to discuss this. Almost all of the pages on the ovirt.org wiki that have "Last Updated:", actually have: Last updated: {{CURRENTMONTHNAME}} {{CURRENTDAY}}, {{CURRENTYEAR}} thus showing the current date and not the last change date. When searching google you see the last time its robot happened to fetch the page. See e.g. [1] for a (possibly non-complete) list. Not sure if that's intended or not, but I personally find it useless and misleading. I guess that someone started it some time ago and everyone else just copied without caring much. Can all of these lines be removed? If anyone really wants to know when was the last change, they can use: http://www.ovirt.org/index.php?title=SOME_TITLE&action=history (which is easily-accessed from the "Page" menu for logged in users. Not sure why it's not the same for non-logged-in ones). It might be possible to add some wiki markup to make it automatically show this, but: 1. I tried a bit and failed (used [2] as a guide) 2. Not sure it's worth it 3. It will increase the load on the server. [1] http://tinyurl.com/nyhgt3j [2] http://www.mediawiki.org/wiki/Help:Magic_words Best regards, -- Didi

[Users] Yum Installation Problems (ovirt 3.3, CentOS 6.5)
by Jon Forrest 22 Feb '14

22 Feb '14

I have a brand new CentOS 6.5 x86_64 installation with all the updates as of today installed. I want to create a test All-In-One node, so I follow the documentation and run yum install epel-release-6-8.noarch.rpm yum localinstall http://ovirt.org/releases/ovirt-release-el.noarch.rpm These work fine. I then run yum install ovirt-engine-setup-plugin-allinone -y and I get Error: Package: libvirt-lock-sanlock-0.10.2-29.el6_5.3.x86_64 (updates) Requires: libsanlock_client.so.1()(64bit) Error: Package: libvirt-lock-sanlock-0.10.2-29.el6_5.3.x86_64 (updates) Requires: sanlock >= 2.4 Error: Package: vdsm-4.13.3-3.el6.x86_64 (ovirt-3.3.3) Requires: sanlock >= 2.3-4 Error: Package: vdsm-4.13.3-3.el6.x86_64 (ovirt-3.3.3) Requires: sanlock-python Is this expected? What's weird is that IIRC I did the same thing last week without problems. Should I just grab newer versions of libvirt? Thanks, Jon Forrest

[Users] [BUG] wrong template shown for vm
by Sven Kieske 21 Feb '14

21 Feb '14

Hi, can anyone reproduce this bug? https://bugzilla.redhat.com/show_bug.cgi?id=1068679 when you create a vm from an imported template (from export doomain) the template info for the vm shows that it is based on the "blank" template. I can reproduce this on ovirt 3.3.3-2.el6 it would be cool if someone could try to reproduce this on 3.4 and on fedora.

[Users] Asking for advice on hosted engine
by Giorgio Bersano 21 Feb '14

21 Feb '14

Hello everybody, I discovered oVirt a couple of months ago when I was looking for the best way to manage our small infrastructure. I have read any document I considered useful but I would like to receive advice from the many experts that are on this list. I think it worths an introduction (I hope doesn't get you bored). I work in a small local government entity and I try to manage effectively our limited resources. We have many years of experience with Linux and especially with CentOS which we have deployed on PC (i.e. for using as firewall in remote locations) and moreover on servers. We have been using Xen virtualization from the early days of CentOS 5 and we have built our positive experience on KVM too. I have to say that libvirt in a small environment like ours is really a nice tool. So nothing to regret. Trying to go a little further, as already said, I stumbled upon oVirt and I've found the project intriguing. At the moment we are thinking of deploying it on a small environment of four very similar servers each having: - a couple of Xeon E5504 - 6 x 1Gb ethernet interfaces - 40 GB of RAM two of them have 72 GB of disk (mirrored) two of them have almost 500GB of useful RAID array Moreover we have an HP iSCSI storage that should easily satisfy our current storage requirement. So, given our small server pool, the necessity of another host just to run the supervisor seems a requirement too high. Enter "hosted engine" and the picture takes brighter colors. Well, I'm usually not the adventurous guy but after experimenting a little with oVirt 3.4 I developed better confidence. We would want to install the engine over the two hosts with smaller disks. For what I know, installing hosted engine mandates NFS storage. But we want this to be highly available too, and possibly to have it on the very same hosts. Here is my solution: make a gluster replicated volume across the two hosts and take advantage of that NFS server. Then I put 127.0.0.1 as the address of the NFS server in the hosted-engine-setup so the host is always able to reach the storage server (itself). GlusterFS configuration is done outside of oVirt that, regarding engine's storage, doesn't even know that it's a gluster thing. Relax, we've finally reached the point where I'm asking advice :-) Storage and virtualization experts, do you see in this configuration any pitfall that I've overlooked given my inexperience in oVirt, Gluster, NFS or clustered filesystems? Do you think that not only it's feasable (I know it is, I made it and it's working now) but it's also reliable and dependable and I'm not risking my neck on this setup? I've obviously made some test but I'm not at the confidence level of saying that all is right in the way it is designed. OK, I think I've already written too much, better I stop and humbly wait for your opinion but I'm obviously here if any clarification by my part is needed. Thank you very much for reading until this point. Best Regards, Giorgio.
