[Users] "Guest Agent Data" under "Network Interfaces" empty

Hi all, I installed ovirt engine 3.4 beta with two VMs - one opensuse 13.1 with ovirt-guest-agent from [1] and another fedora 19 with oga from fedora. Both of them seem to work well - I can see installed applications, logged in user, memory usage. But in both of them, under "Network Interfaces", the "Guest Agent Data" tab on the right has just headers, with no data. 'vdsClient -s 0 getAllVmStats' on the host does show such data correctly for both VMs. Am I missing anything? Is it a bug, or I should do something to get there data from the agent (through vdsm)?
