Why does network connection hang in virtual machines while downloading large files?

Solution Verified - Updated -


  • Installed virtio drivers in windows 2008 from virtio-win-1.1.16.iso.
  • When downloading a very large file over the network, the virtual machine loses connection to the network.
  • The physical host is unaffected and other virtual machines on the same bridge are also unaffected.
  • It seems a failure of virtio network driver.
  • The old driver installed from virtio-win-1.0.1-52454.iso, was not having this issue.


  • Red Hat Enterprise Linux 6.x (host)
  • Windows 2008, 2008 R2 (guest)
