I am aware my guest OS is out of support but I experienced the following:
oVirt - 4.2.8 (self-hosted engine)
VM - CentOS 5.2; two VNIC's ( driver used e1000) connected to different VLAN's; -
no issues with network connectivity
After upgrade to oVirt 4.3.7
The same VM starts normally. Network is available for several seconds (10 - 20 pings) and
then it disappears. The machine works but no ping to/from VM. When I am returning the same
machine (via export domain) to oVirt 4.2.8 environment - it works as expected.
Can someone advise on this? Any help will be greatly appreciated.
