Windows 2008 – Poor Performance

I was noticing on a few installs I had that there was delays between clicks and seemed sluggish. Those installs were running Hyper-V which was effecting the VMs also. After bunch searching around I found some hints towards Intel based Network cards. My guess was it had to do with Windows 2008/Vista Offloading and the Intel Large Send Offloading.

Fedora 10 on Hyper-V - Kernel Panic

Kernel panic – not syncing: Out of memory and no killable processes

This error seems to happen below 1024MB RAM for me. To fix this issue add more then 1024MB of RAM. From what I found the RAM specs for Fedora 10 are 512 but I can’t get it to run that low.

Memory requirements for x86_64
  • Minimum RAM for text-mode: 256MiB

  • Minimum RAM for graphical: 384MiB

  • Recommended RAM for graphical: 512MiB

Windows 2008 Failover Clustering - Unable to add node

The computer ComputerName is joined to a cluster.

This might affect other versions of failover clustering but this happened on windows 2008. The Add Node Wizard checks the server’s cluster service if its disabled or automatic. If for some reason its still set to startup type automatic that message will come up. To fix this issue all you have to do is set this to disabled again. That is assuming that is server has been correctly removed from any previous clusters.
