Problem: Running Windows Server 2008 R2 Standard 64bit in KVM Environment. At random times the kvm networking just seems to go belly-up. Server wont respond to pings. Have to use VNC console to log into server and Disable/Enable Network Adapter and then it works fine until the next outage. Occurs with both the virtio and e1000 network drivers. Windows event viewer shows no issues.
Any assistance would be appreciated.
