[Users] Limit migration bandwidth
by Joop 14 Jul '13

14 Jul '13

Hi All, I have seen this question asked before and seen it answered but can't find it back on either the mailinglist or IRC, probably because I don't use the correct search term but can't dream up any new ones so I'm asking: How to limit the amount of VM's that can simultaneously be migrated and how to limit the bandwidth used by migrating VM's? Looked at vdc_options, engine-config but have run out of ides. Thanks in advance, Joop -- irc: jvandewege

[Users] NIC problem with ovirt node
by Jason Keltz 13 Jul '13

13 Jul '13

I've just installed my first ovirt node using the 2.6.1 image. I have 5 network interfaces in the machine .. ovirt sees them as: em1, em2, em3, em4, and rename6! That last one seems a little odd, but that's a different issue, I guess. From dmesg.. > [ 4.650156] systemd-udevd[213]: renamed network interface eth2 to em4 > [ 4.656189] systemd-udevd[212]: renamed network interface eth0 to em3 > [ 4.662193] systemd-udevd[209]: renamed network interface eth1 to em2 > [ 4.670385] systemd-udevd[214]: Tried to rename network interface > eth3, but the target name em2 already exists! The names that udev > rules assign to network interfaces must be changed. Avoid names that > collide with kernel created ones. A workaround will be attempted now, > but this WILL BREAK in a future release! See > https://bugs.freedesktop.org/show_bug.cgi?id=56929#c3 > [ 4.675179] systemd-udevd[214]: renamed network interface eth3 to > rename6 What IS a big deal is that every time I configure one network interface, the others go back to "unconfigured". I'm told this is because I should only configure one on the ovirt-node, and then use the engine to configure the rest. Okay -- does it say that somewhere that I missed? :) but when I'm in the engine, I can click on the node, and see that it's up. I can click on network interfaces, and see that one is up, and the other are down. I can create networks on the engine, and I can assign the nodes interfaces to those networks, but for the life of me, I can't figure out where I assign an IP to the nodes interfaces!! Surely, the place to do that would be under the "Host" tab, yet it doesn't seem to be there... Any help would be much appreciated. Jason.

[Users] Unable to view console via SPICE method on EL6.
by Jason Keltz 13 Jul '13

13 Jul '13

I'm running with theEL6 release of ovirt-engine: ovirt-engine.noarch 3.2.2-1.1.el6 @ovirt-stable After creating a virtual machine, I cannot view the console if protocol is set to "SPICE". If the protocol is set to VNC, I can view the console, but it's not very convenient since I have to load a separate VNC viewer, and enter the IP and port of the engine, and a randomly generated password each time. How does one make console work via SPICE? Is this a known issue because RHEL6 wouldn't have all the updated libraries of later a later Fedora release? Jason.

Hi everyone, I'm trying work with Gerrit, but this it insists in not accept my public key. I followed all steps in this documentation: http://www.ovirt.org/Working_with_oVirt_Gerrit I joined with my user: "firemanxbr"(firemanxbr.id.fedoraproject.org) with my e-mail: mr.marcelo.barbosa(a)gmail.com in web interface, in this environment it's okay.

[Users] exception occured when adding NFS storage

I used one server as the ovirt.engine, and another server as the ovirt.host= . Both servers run Fedora 18. After executing the command "engine-setup" in the ovirt.engine, I can get i= nto the admin portal to start the configuration of host, storage, etc. Here= was what I am doing: 1. In the Default data center, I clicked the Guide Me icon. The firs= t thing is to configure the host. After waiting for 4-5 minutes, I saw the = host ovirt.host is displayed under the Host tab with the Up status. 2. On the ovirt.engine server, I did the following before creating th= e storage: mkdir -p /mnt/data chown -R 36:36 /mnt/data Add the following line to /etc/sysconfig/nfs: NFS4_SUPPORT=3D"no" Add the following line to /etc/exports: /nmt/data *(rw,sync,no_subtree_check,all_squash,anonuid=3D36,anongid=3D= 36) systemctl restart nfs-server.service 3. Back to the Default data center, clicked the Guide Me icon to star= t the configuration of new storage. 4. On the New Storage dialog, set Name field to be NFS-Share, and set= the Export Path field to be ovirt.engine:/mnt/data. Then click OK After couple of minutes, I saw the error window popped up: Error: Cannot ad= d Storage.

[Users] which file system for shared disk?
by Piotr Szubiakowski 11 Jul '13

11 Jul '13

Hi, we are developing an application where would be great if multiple host could have access to the same disk. I think that we can use features like shared disk or direct LUN to attach the same storage to multiple VM's. However to provide concurrent access to the resource, there should be a cluster file system used. The most popular open source cluster file systems are GFS2 and OCFS2. So my questions are: 1) Does anyone have share disk between VM's in oVirt? What fs did You used? 2) Is it possible to use GFS2 on VM's that are running on oVirt? Does anyone have run fencing mechanism with ovirt/libvirt? Many thanks, Piotr
