Virtual Machine loosing network connections at random
Posted on 2014-08-11
A Virtual Machine that contains Disk2VHD image of a SBS2008 server resides on a Server 2012 R2 Host.
The Host is a Gen 8p HP ProLiant with four NICs so the VMs have a NIC each. There is one other VM on the Host which is a Disk2VHD 2003 Server with (so far) no issues.
The SBS08 has one vNIC assigned to it and when the VM looses its network connection, I log on to the Hyper-V host and assign another vNIC to the VM and the connection is restored. Then days later it looses connection to move it back.
- SR-IOV was enabled and disable, no difference
- MS WFP is enabled
- Changed network cable even but no difference
All NICs are connected to a 48 port managed HP ProCurve switch.
Does anyone have any ideas?
