adding LINKDELAY to ovirtmgmt when vdsm configures it
by Jason Keltz 07 May '15

07 May '15

Hi. Is it possible through engine to specify configuration parameters for network interfaces that must be passed through on initialization? For example, I need em1 and em2 configured with "LINKDELAY=10". I can add it after the fact, but I don't want to do that. I want vdsm to configure the interface with that setup already the first time. Jason.

selectively disabling IPv6 on bridges
by Rik Theys 07 May '15

07 May '15

Hi, I'm looking for a way to selectively disable IPv6 on the bridge interfaces on the oVirt hosts. When oVirt creates the bridges for all logical networks on the host, it keeps the default settings for IPv6 which means all bridges get a link-local address and accept router advertisements. When a VM is created on the logical network, it can now reach the host over IPv6 (but not over IPv4 if no IP address has been assigned on the host). If it sends out a router advertisement it can even create a global IPv6 address (haven't tested this). How can I prevent this? I would like to prevent the guest from IPv6 access to the host but the guest itself still needs IPv6 access (global IPv6 addresses). Is it sufficient to create a sysctl config file that says: net.ipv6.conf.default.disable_ipv6 = 1 ? Regards, Rik -- Rik Theys System Engineer KU Leuven - Dept.

High number of XFS extents migrating disk from iscsi to Gluster
by Adrián Santos Marrero 07 May '15

07 May '15

Hi!, I've been migrating my Ovirt storage from iscsi to Gluster. What I've been doing is moving the disks with the VM powered off. This procedure was fine until I tried to migrate a 100GB disk from a VM with an Oracle DB. During this migration the access to Gluster slowed down, affecting the whole cluster (VDSM timeout in oVirt Engine, VM's entered in unknown state, gluster client disconnected from a brick) What I found in gluster servers was a XFS error: XFS: possible memory allocation deadlock in kmem_alloc (mode:0x250) And this error is due to the number of extents of the file (~ 8M): gluster01:/gluster/ovirt1_brick_01/brick/89c4e113-1003-4b4e-850e-e7fc5bf2edc6/images/e5b7fc46-4168-4019-a13a-f9b7093d0534# > xfs_bmap f9cd555d-fd98-499f-a853-d0ce76eecd37 | wc -l > 8627613 > I'm using Gluster 3.6.2 and Centos 7 (3.10.0-229.1.2.el7.x86_64 kernel). Does anyone know why is qemu-img generating this so fragmented file?

Hi all, Hi installed two nodes with the 3.5.1 ISO. Now I want to upgrade them to 3.5.2 new ISO. I uploaded the ISO file to my ISO domain with engine-iso-uploader command. But I can't choose my ISO file in the Manager to upgrade my nodes. How can I select the good Iso file ? Thanks --- Kevin

autologin into vm desktop
by Adolfo 07 May '15

07 May '15

Hello, My name is Adolfo. I'm in charge of the development of UDS, an open source connection broker (with commercial support if requested) (http://www.ovirt.org/Universidad_de_Sevilla_Case_Study is done with it for example). I don't know if this is the place to post this "request for help", if not, please forgive me :) The case is that we are including Spice as an accepted protocol for connecting to VMs (currently we allow rdp, rgs, nx, ...) provided by oVirt, and we have found the following "issue". It's ease to get the connection parameters for the VM using REST api, even get the ticket for allowing connection, but i have been looking for a way "logging user" directly into desktop, not only connect to "display" but also "log in" into remote without needed to use a second authentication. I have seen that oVirt Portal currently allows this, and i have found also that vsdClient can do login using "vdsClient -s <HOSTIP> desktopLogin <VMID> <DOMAIN> <USER> <PASSWORD>", and although it is possible to use this, it will be a bit "tricky" to get it working i think. My question is... ¿Is any way of doing "desktop login" using REST API, or any other "simple method" from an external app such as this broker?. ¿If yes, how? :-) ¿If not, will be support for this an anyone knows how? Thank you, and again, if this is not the correct list, sorry for the annoyance. Adolfo Gómez
