[Users] Booting oVirt CentOS nodes from PXE ?
by Matt . 19 Jun '13

19 Jun '13

Hi All, I'm wondering if it's possible to PXE boot nodes so we don't need to install every server on local disks. I have read something in the docs about a Fedora ISO, but how does this work and will it be possible with CentOS ? Thanks! Cheers, Matt

[Users] Disk move when VM is running problem
by Gianluca Cecchi 18 Jun '13

18 Jun '13

Hello, oVirt 3.2.1 on f18 host I have a running VM with one disk. Storage domain is FC and disk is thin provisioned. VM has preexisting snapshots. I select to move the disk On the top part of the window I note in red this message: Note: Moving the disk(s) while the VM is running Donna if it is a generale advice... I proceed and I get Snapshot Auto-generated for Live Storage Migration creation for VM zensrv was initiated by admin@internal. Snapshot Auto-generated for Live Storage Migration creation for VM zensrv has been completed. User admin@internal moving disk zensrv_Disk1 to domain DS6800_Z1_1181. during the move: Total DISK READ: 73398.57 K/s | Total DISK WRITE: 79927.24 K/s PID PRIO USER DISK READ DISK WRITE SWAPIN IO> COMMAND 29513 idle vdsm 72400.02 K/s 72535.35 K/s 0.00 % 87.65 % dd if=/rhev/data-cent~nt=10240 oflag=direct 2457 be/4 sanlock 336.35 K/s 0.33 K/s 0.00 % 0.12 % sanlock daemon -U sanlock -G sanlock 4173 be/3 vdsm 0.33 K/s 0.00 K/s 0.00 % 0.00 % python /usr/share/vdsm~eFileHandler.pyc 43 40 8760 be/4 qemu 0.00 K/s 7574.52 K/s 0.00 % 0.00 % qemu-kvm -name F18 -S ~on0,bus=pci.0,addr=0x8 2830 be/4 root 0.00 K/s 13.14 K/s 0.00 % 0.00 % libvirtd --listen 27445 be/4 qemu 0.00 K/s 44.67 K/s 0.00 % 0.00 % qemu-kvm -name zensrv ~on0,bus=pci.0,addr=0x6 3141 be/3 vdsm 0.00 K/s 3.94 K/s 0.00 % 0.00 % python /usr/share/vdsm/vdsm vdsm 29513 3141 14 17:14 ? 00:00:17 /usr/bin/dd if=/rhev/data-center/5849b030-626e-47cb-ad90-3ce782d831b3/013bcc40-5f3d-4394-bd3b-971b14852654/images/01488698-6420-4a32-9095-cfed1ff8f4bf/2be37d02-b44f-4823-bf26-054d1a1f0c90 of=/rhev/data-center/5849b030-626e-47cb-ad90-3ce782d831b3/14b5167c-5883-4920-8236-e8905456b01f/images/01488698-6420-4a32-9095-cfed1ff8f4bf/2be37d02-b44f-4823-bf26-054d1a1f0c90 bs=1048576 seek=0 skip=0 conv=notrunc count=10240 oflag=direct After some minutes I get: User admin@internal have failed to move disk zensrv_Disk1 to domain DS6800_Z1_1181.

[Users] CentOS 6 and multiple ISCSI interfaces/multipath
by Martin Goldstone 18 Jun '13

18 Jun '13

Hi all, I've recently started looking at oVirt to provide the next iteration of our virtualization infrastructure, as we have recently acquired some ISCSI storage. Up to now, we've been using KVM managed by libvirt/virt-manager locally on each of our hosts, using direct attached storage, which was obviously less than ideal. In setting it all up, I've hit a bit of a snag. We've got 4 GbE network interfaces on our pilot host (running vdsm on CentOS 6.4) which are connected to our storage arrays (equallogic). I've created 4 interfaces with iscsiadm for these and bound them, but when setting up the discs in oVirt, I've not seen a way of telling it which interfaces to use. The node makes the connection to the target successfully, but it seems its only connecting via the "default" iscsi interface, and not making a connection via each interface that I've defined. Obviously this means I can't use multipath, and being only GbE interfaces it means I'm not getting the performance I should. I've done some searching via Google, but I've not really found any thing that helps. Perhaps I've missed something, but can anyone give me any pointers for getting this to work across multiple interfaces? Thanks? Martin

HI All, I upgraded to 3.3 and tried to start a console. Whatever version of console I set, VNC or Spice, the browser downloads a console.vv file now. Am I doing something wrong or is this just the unreleased version ? Thanks for the help! Cheers, Matt

Hi guys, I've got some problems with my ovirt-engine. Currently I have one iscsi storage volume and I want add a second one. The second has the same configuration as the first. In my engine I can log into the iSCSI but I cannot see the LUN. Ovirt gives me this message : 2013-06-17 15:50:04,013 ERROR [org.ovirt.engine.core.bll.storage.DiscoverSendTargetsQuery] (ajp--127.0.0.1-8702-9) Query DiscoverSendTargetsQuery failed.

[Users] cpu stuck after joining fedora 18 node to ovirt
by Daniele Pavia 17 Jun '13

17 Jun '13

Dear all, we're facing this issue while trying to join a Fedora 18 server with the latest stable vdsm to an instance of ovirt-engine 3.2.2. Let's put things in context: we have this fujitsu rx200 server with a dual emulex fc nic connected with two fibres that go through two brocade switches, which in turn have four paths each to a vnx 5300 storage - that's a grand total of eight paths. Now. This server was previously employed as an ovirt node and was working correctly with the very same configuration, we simply reinstalled the server with the latest Fedora 18 stable release. The server boots fine and multipathd is already up and running. All the paths are valid and block devices are seen. Please note that those block devices contain our ovirt 's d.c. storage domains. We set up and enable ovirt's stable repo and proceed to install vdsmd, then we add the node from the webadmin interface. Bear in mind that we face the same issue by letting the engine install the vdsm daemon on its own. The node gets installed successfully and reboots. When the OS tries to initialize the storage we get this funny message about a random core getting stuck for xx seconds. Then it fails to mount /home and finally drops to the emergency shell. (see attachment) If we remove the host from the storage group and reboot it, it doesn't hang. A few things we tried to fix this up: * restored multipath.conf from a working node * put each mountpoint's uuid inside fstab * installed vdsm from fedora updates instead of the official ovirt stable * swapped two different fujitsu models (we had the same issue with another server: we swapped them and had the first one join a rhev infrastructure running on the same network without shedding a single tear) We consciously avoided installing ovirt node since we require more control out of our servers than such a minimal distribution will ever let us have, however we're willing to deploy it for troubleshooting purposes. Any feedback will be more than welcome. Cheers, Daniele Pavia
