Hyper-V showing max CPU usage for my Ubuntu VM

Last Modified: 2012-05-12

I have Ubuntu 10.04 Server running under Hyper-V on a Windows 2008 R2 server. SSH enabled. Using one Legacy Network Adapter, static IP.

Everything works, but normally once a day it will get 'stuck', chewing up the entire CPU committment for that VM (even when there is no visible activity in the VM itself - using HTOP to monitor it) until the VM is turned off and back on again.

I've tried installing the 'hv_' modules and using a regular Network Adapter (which does work, but same problem crops up) made sure 'ntpdate' is correct, checked the event logs on the VM Host (couldn't see anything obvious there) and tried turning off IPv4 Checksum Offload on the Host's virtual and physical NICs.

Problem still occurring.
