Poor I/O from new VMs where Hyper-V Host is okay
Posted on 2014-02-15
I have a newly installed Server 2012 R2 on a HP ML 350p G8 server.
Hyper-V Role installed and configured with two VMs on it.
The VMs are Running 2012R2 Gen2 VM and 2008R2 Gen1 VM.
All VMs and Host have their own dedicated NIC.
All default NIC settings. RSS enabled etc...
On the 2012 R2 VM I am copying files from an 2003 R2 physical server, but the transfer speed is horrendous, where the same files from the 2003 R2 server copied must faster to the host.
No cluster involved, Gig switch on the LAN,
The same issues on the 2008 R2.
Built a second 20012R2 VM but no difference.
Can anyone guide me on this please?
