Re: How to disable NMI watchdog?

[Kernel Guardian <kernelgardian@xxxxxxxxx>]

As Reindl wrote for virtualzation is better to use some bare-metal system. Beside VMWare there are other virtualization solutions: KVM with VirtualManager or Ovirt, Xen/Citrix, Openstack, VirtualBox, Choosing the right solution depends on your needs. My opinion and experience says that the use only one server in a production environment can be very risky business. A few moths ago I was put in production environment one Ovirt 3.1 instalation over F17. (2 nodes for Virtualzation with 10+ virtual machines, mixed Linux and Windows, with live migration )     
For now, I am very pleased with Ovirt as a virtualization solution. Ovirt can be installed on Centos 6.x also, with some hardware HCL problems, depending on hardware you are using.

Also i was build up HA ISCSI storage over Centos/F17 over 1Gbps dedicated network. So far I am satisfied with the performance of the system. ( I hope that management will soon provide some money for 10Gbps network.:) )

however DO NOT INSTALL VMware Server
VMware Server is EOL and not updated since THREE YEARS
 
you can stick with VMware Player if it must be free
or buy VMware Workstation which is not really expensive
