ovirt-guest: Network device hanging shortly after startup (after Upgrade to 4.3.5)

We have a some old guests (SLES 10.4) which has been worked corectly till 4.2.7 (Manager + Host) After Upgrade to 4.3.5, we have got a network issue, that the gues network device, not depending on used device type, stopts to work after some seconds.... after about 15-20 pings device is hanging. Sometimes, in the first time after the device hungs up, the message "no buffer space available" comes from ping. Does someone knows a solution for it? greetings Julius

When you go to Edit VM -> System -> Advanced Parameters (right hand side) -> Custom Compatibility Version do you have the option for 4.2 ?If yes, can you set it to 4.2 and then poweroff + poweron the VM ?

Is the issue solved if the VM attribute "Custom Emulated Machine" is set to "pc-i440fx-rhel7.3.0”? This should use virtual hardware whch is more close to oVirt 4.2 .
