Hi, I'm currently experiencing packet loss on a Windows Server 2012 R2 Hyper-V Cluster that hosts several VMs which are also having this same behavior.
The Hyper-V Servers each have 10 NICs:
- 1 dedicated for administration and domain validation
- 2 dedicated for the VMS
- 4 are connected to an iSCSI SAN (separated switches)
- 1 for Live Migrations
- 1 for Heart Beat
- 1 for Backups
The strange thing is that both the NIC use for administration and the NICs used for VMs are having the same problems, if I start pinging any Hyper-V host, the response time times-out from time to time. The same on the VMs, all of them are having trouble and the packets either takes a while to respond or time-out.
None of the NICs are using teaming.
The NICs that are used for the VMs doesn't have any tcp/ip settings configured on the Hosts.
I have all the latest patches install until today. This is happening across all the nodes of the Hyper-V cluster.
This doesn't happen to any other physical servers on the network.
Any ideas are appreciated!
Thanks
