[Users] Stack trace caused by FreeBSD client

by Johan Kooijman

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 … [View More]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

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

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.

[Users] (no subject)

by Koen Vanoppen

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#Conne... 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

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. … [View More]
