Hello, we are seeing Guest VM's disconnect from the network in the event logs during our backup window. We are using CommVault 10 SP8 on Hyper-V 2012 R2 with Hyper-V role, we are fully patched and using the current Integration Services. We see this on both stand alone Hyper-V servers and clusters. The servers are being backed up with VSS and are not going into a saved state as far as I can tell, they are being hot backed up.
We are seeing event ID 12598 network adaptor disconnected from virtual network on the host logs under Hyper-V-SynthNic. I would like to try and stop this from happening so monitoring software will stop marking servers offline. Any ideas?
