Hi,
Not really.
I can resolve temporally, unconfiguring the bond and then configure it again.
But when i reboot the server the problem comes back.
can you compare the network configuration before and after you change it the setup network?
Perhaps you can send pastebin of a 'vdsClient 0 getVdsCaps' (or 'vdsClient -s 0 getVdsCaps' if the first doesn't work) from the host when the bond is slow, and one after you break and create it again? if you don't have vdsClient command you can 'yum install vdsm-cli' and it should be available.

Hi Ricardo, Are you still experiencing the problem described below? Are you configuring MTU (to something other than default or 1500) for one of the networks on the bond?
Thanks, Livnat

Good afternoon,
Yes, the "Save network configuration" is checked, configurations are persistent across boots.
The problem is not the persistence of the configurations, the problem is that after a reboot the network performance on the VMs is very bad, and to fix it i need to remove the bonding and add it again.
In attachment, the screenshots of my network configuration.
Best regards, Ricardo Esteves.

Hi,
I've got ovirt installed on 2 HP BL460c G6 blades, and my VMs have very poor network performance (around 7,01K/s).
On the servers itselfs there is no problem, i can download a file with wget at around 99 M/s.
Then i go to ovirt network configuration remove the bonding and then make the bonding again and the problem gets fixed (i have to do this everytime i reboot my blades).
Have you tried to check the "Save network configuration" check box, or clicking the button from the host's NICs sub-tab?
This should persist the configuration that you set on the host across reboots..
SERVER' s Software: CentOS 6.4 (64 bits) - 2.6.32-358.6.2.el6.x86_64 Ovirt EL6 official rpms.
Anyone experienced this kind of problems?
Best regards, Ricardo Esteves.
