3rd party qemu/libvirt rpms and ovirt
by Tiemen Ruiten 08 Jul '14

08 Jul '14

Hello, I'm trying to setup a new oVirt environment based on F19 hosts, but I'm running into so many issues, that I'm thinking of switching 'back' to CentOS. However I would lose the advanced features (libgfapi, live snapshots etc.) that are enabled in the F19 libvirt/qemu/kvm packages. So after some googling a came across Alexandar Evseev's repository with all the newest virtualization rpms packaged for CentOS 6: http://download.opensuse.org/repositories/home:/aevseev/CentOS6/x86_64/ However, I can't find any information at all about the status of these packages or any indication about stability. Is anyone familiar with this repository and would it be possible to use these packages in an oVirt environment? -- Tiemen Ruiten Systems Engineer R&D Media

Re: [ovirt-users] iSCSI and multipath
by jplorier＠gmail.com 07 Jul '14

What do you mean by "having direct lun working" ? You already can, you need to add to the first line of multipath.conf a comment to make it private (don't remember the exact content) then you can set your luns in every host as desired. The bad thing is that you'll have to replicate the file to every host everytime you make changes. I did open an RFE in the past about this... I don't remember for sure as I'm not active to ovirt since a long time now.

iSCSI and multipath
by Nicolas Ecarnot 07 Jul '14

07 Jul '14

Hi, Context here : - 2 setups (2 datacenters) in oVirt 3.4.1 with CentOS 6.4 and 6.5 hosts - connected to some LUNs in iSCSI on a dedicated physical network Every host has two interfaces used for management and end-user LAN activity. Every host also have 4 additional NICs dedicated to the iSCSI network. Those 4 NICs were setup from the oVirt web GUI in a bonding with a unique IP address and connected to the SAN. Everything is working fine. I just had to manually tweak some points (MTU, other small things) but it is working. Recently, our SAN dealer told us that using bonding in an iSCSI context was terrible, and the recommendation is to use multipathing. My previous experience pre-oVirt was to agree with that. Long story short is just that when setting up the host from oVirt, it was so convenient to click and setup bonding, and observe it working that I did not pay further attention. (and we seem to have no bottleneck yet). Anyway, I dedicated a host to experiment, I things are not clear to me. I know how to setup NICs, iSCSI and multipath to present the host OS a partition or a logical volume, using multipathing instead of bonding. But in this precise case, what is disturbing me is that many layers described above are managed by oVirt (mount/unmount of LV, creation of bridges on top of bonded interfaces, managing the WWID amongst the cluster). And I see nothing related to multipath at the NICs level. Though I can setup everything fine in the host, this setup does not match what oVirt is expecting : oVirt is expecting a bridge named as the iSCSI network, and able to connect to the SAN. My multipathing is offering the access to the partition of the LUNs, it is not the same. I saw that multipathing is talked here : http://www.ovirt.org/Feature/iSCSI-Multipath I here read : > Add an iSCSI Storage to the Data Center > Make sure the Data Center contains networks. > Go to the Data Center main tab and choose the specific Data Center > At the sub tab choose "iSCSI Bond" The only tabs I see are "Storage/Logical Networks/Network QoS/Clusters/Permissions". In this datacenter, I have one iSCSI master storage domain, two iSCSI storage domains and one NFS export domain. What did I miss? > Press the "new" button to add a new iSCSI Bond > Configure the networks you want to add to the new iSCSI Bond. Anyway, I'm not sure to understand the point of this wiki page and this implementation : it looks like a much higher level of multipathing over virtual networks, and not at all what I'm talking about above...? Well as you see, I need enlightenments. -- Nicolas Ecarnot

CentOS dependencies on 3.5
by Jon Archer 06 Jul '14

06 Jul '14

Hi, Just tried to run an update to 3.5 beta and i'm seeing dependencies that are not satisfied. Error: Package: vdsm-jsonrpc-java-1.0.0-0.0.master.el6.noarch (ovirt-3.5-pre) Requires: codehaus-jackson-core-asl Error: Package: vdsm-jsonrpc-java-1.0.0-0.0.master.el6.noarch (ovirt-3.5-pre) Requires: codehaus-jackson-mapper-asl Any ideas? I've done a bit of googling and not uncovered much. Looking at the specfile there seems to be a requirement for jackson, which isn't in the C6 repos but does seem to be in the C7 repos. Thanks Jon
