[Users] adding biosdevname=0 to kernel grub line on ovirt-node persistent
by Jason Keltz 15 Jul '13

15 Jul '13

Hi. I'm wondering if it's possible to modify the kernel line (in my case, appending "biosdevname=0") on an installed ovirt-node? Adding it during boot works - I'd just like to know how to make the change persistent. Thanks, Jason.

[Users] f19 guest in oVirt 3.2.2 considerations
by Gianluca Cecchi 15 Jul '13

Successfully installed f19 x86_64 guest desktop via pxe. Vm configured in oVirt as other linux run yum update after install qemu-kvm process command line on host for this VM contains: -vga qxl -global qxl-vga.vram_size=671088 On F19 VM xorg qxl driver automatically installed and used and also spice-vdagent I had to manually install ovirt-guest-agent from standard fedora repo --> perhaps it would be nice to have it some sort of automatically installed in oVirt guest... how? I put guest in full screen, aka in my setup 1680x1050 Able to use gnome 3 even if quite slow. As soon as I start firefox and begin to use it I get this in Xorg.0.log ...

[Users] host remains in status unassigned
by Gianluca Cecchi 15 Jul '13

15 Jul '13

Hello, oVirt 3.2.1 on F18 One mgmt server + one host. At some point the host had some problem and was rebooted at reboot ther was a problem because I got detected unhandled Python exception in '/usr/share/vdsm/vdsm' watching at http://www.ovirt.org/Troubleshooting I verified that for some reason vdsmd.log was root.root. So I set correct permissions and restarted the node. Now it stays at "unassigned" status from an engine point of view, that I don't know what means...

[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.

[Users] exception occured when adding NFS storage
by Zhang, Hongyi 11 Jul '13

11 Jul '13

--_000_B5488210B44F434FA68B7430CC196BCFA701F041ALAMBBcorpadwrs_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi, I started to learn the oVirt by following the oVirt Quick Start Guide. 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.

[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

[Users] [URGENT] VMs not starting
by Juan Pablo Lorier 09 Jul '13

09 Jul '13

Hi, I've tried with a brand new fedora vm without OS and I have the same error. I've made the configuration change proposed by Joop not only for 3.2 version but also for 3.1 just in case something stays in the vms after creation (as they were not exported and then imported, just used the LUN). I hope someone can give me a hand in this. Regards,

[Users] RAID1 mirror on ovirt-node + engine nfs server
by Jason Keltz 09 Jul '13

09 Jul '13

Hi. I've been reading about ovirt, and ready to try my own experiments with it. I have two small questions.. When an ovirt-node is installed from the standard ISO, there's no mention in the documentation about setting up a RAID1 mirror for the root disk on the node. I'm sure that once I get around to working out kickstarting the node, I could easily install the raid1 mirror, but I'm just wondering why I don't see that in the default ISO. Maybe I'm just missing something. Is redundancy of the disk on the node not important? Sure, if the node goes down, I guess the VMs could be run on other nodes, but if we can prevent the node from going down in the first place, then why not? I also have a question about the storage backend. In particular, I have a pretty powerful server that I intend to use as the NFS server, and a few servers to use as nodes. On the other hand, I don't have a powerful machine (at the moment) to use for the ovirt-engine. Would it be poor practice to run the ovirt-engine ON the NFS server? During engine setup, I see that you can setup an NFS share for ISOs from the ovirt-engine, but I don't think there's mention of just generalized storage there. I suspect it's "poor practice", but I thought I'd ask anyway. My setup will be relatively small (say, 4 nodes), and this would let me reduce 1 general server from the infrastructure (dedicated ovirt-engine). Thanks! :) Jason. ps: At the moment, I am not subscribed to users - please cc: me on responses.

[Users] libgovirt 0.2.0
by Christophe Fergeau 08 Jul '13

08 Jul '13

--hoZxPH4CaxYzWscb Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hey, I've just made a new release of libgovirt. libgovirt is a GObject C library to access oVirt/RHEV[1] REST API[2]. At the moment, it's able to get the list of VMs available on an oVirt instance, and to get the connection details for a given VM. This release mainly consists of internal refactoring to make it easier to support new parts of oVirt REST API, and to get it to work with older glib versions. However, it also has minor API breaks, and changes the library soname because of ABI breakage. It can be downloaded from http://people.freedesktop.org/~teuf/govirt/libgovirt-0.2.0.tar.xz It's signed with my GPG key: A525 E3EA 186A AB45 DD0F 86AF 24A4 69FB 7A56 F78E Changes since 0.1.0 - Rename OvirtVm::uuid to OvirtVm::guid to match oVirt terminology - Break ABI :( - Switch back to using GSimpleAsyncResult (from GTask) to gain compatibility with older glib versions - Refactor internals to make it much easier to add support for more REST collections - Parse more VM states from the OvirtVm resource Christophe [1] http://www.ovirt.org/Home [2] https://access.redhat.com/site/documentation//en-US/Red_Hat_Enterprise_Virt… --hoZxPH4CaxYzWscb Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (GNU/Linux) iEYEARECAAYFAlHal+cACgkQJKRp+3pW9462dgCcDtQXNqPSLW9JA6LX6Zy4GCUb bNUAnA5OStLSLs1bZxRaQl+kYo32S21Y =fbuI -----END PGP SIGNATURE----- --hoZxPH4CaxYzWscb--

Nor is support for mdraid devices, to be honest. It's something worth considering (whether btrfs redundancy or mdraid), but it's not currently implemented to my knowledge. I could be wrong about that. I also have a question about the storage backend.

This is definitely a workable use case, especially for small environments.
