Recently I installed Windows 2008 x64 VM and installed xentools 6.0.2. VM was so slow and i couldn’t do any tasks. Sounds as a bug with xentools 6.0.2, couple of options to get it fixed
- Rollback to xentools 6.0
- Or “Disable Offload options” in the NIC properties.
- I disabled all properties in Advanced tab, you can try disabling individual options.
