How to disable NMI watchdog?

[Subhas Sing]

Hello, I am trying to install vmware server in Fedora 16. I tried to disable NMI watchdog kernel parameter. Can anybody please let me know how do it ? I followed following procedure but without success!!
$ cat /proc/sys/kernel/nmi_watchdog If you get a '1', then the feature is enabled  and must be turned off or VMs will mysteriously crash. To turn off  nmi_watchdog is different for Fedora 15 and Fedora 16: [5] Fedora 15: Edit /boot/grub/grub.conf and add “nmi_watchdog=0” to the kernel line.[5] Fedora 16: Edit /etc/default/grub and add “nmi_watchdog=0” to the GRUB_CMDLINE_LINUX. Then run:
# grub2-mkconfig -o /boot/grub2/grub.cfg”
to rebuild the grub configuration.
Now, reboot the system and check the /proc/sys/kernel/nmi_watchdog parameter again to make sure you see a '0'.

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

Thanks Reindl for quick reply. Actually we have of lot of instance already running with it in Microsoft Server as host OS. We are planing to move 64 bit feroda server.

Thanks,
Subhas

consider VMware ESXi 5.1

a dedicated bare-metal virtualization has dramatically better
performance than a general purpose system

ESXi itself is for free, maybe hardware HCL is the main problem
the main benefit is that you can everytime upgrade to a commercial
license and make use of Vmotion, HA, shared storage etc. if you
start to need extended features

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.:) )

Fedora 16 is old.  Go for 17.  Or wait some days and get 18.
