I am running Hyper-V on a Windows 2008 R2 server. The Host server has 12 Hyper-V guests running on it. I have two 1GB NIC cards teamed together. One of the virtuals on this host is my agency's file server running Windows 2008 R2 as well. About three months ago I started noticing slow performance (ie 7 MB/sec) when trying to copy a file from this virtual file server to another physical server. I'm not seeing the same performance issues on the other virtuals on this host. Just this one.
How does one troubleshoot network performance issues of a virtual system?
