Hi,
We have Vmware ESX4.0. and three virtual machine are installed on this ESX server. All guest OS are RHEL5.2.
The hardware details is
Server : HP ProLiant BL465cG5
CPU : 8CPUs X 2.1 Ghz
RAM : 16 GB
Processor type : Quad-core AMD opteron(tm) processor 2352
I am getting the following error and after that error guest os get hung, I have to power off and power on the particular virtual machine
The error is below
" The CPU has been disabled by the guest operating system. You will need to power off or reset the virtual machine at this point."
We have other VMWare ESX4 servers and all are running well. Wwe are facing this problem in single VMware ESX server.
Kindly help me to sort out this.
Thanks

Although is just listed to SLES, check if this applies to you.

Hi,
This is not applicable in our case as we are using RHEL5.2 64bit as guest OS on VM ESx 4.0
Well, just sharing a bit of experience. As you certainly know, Linux distributions share almost all kernel code between them. This problem happens because of the relationship between the kernel and certain processor flags you have.
You should take a look on upgrading your kernel, or just trying to call RedHat to check if they can't resolve this for you.

Thanks for ur reply.
We have noticed this issue only when the guest OS is taking load,. We will analyse further.
This is no error IMHO
Probably you have installed the guest with old virtual hardware type 4 or earlier.
This does not support ACPI functions of the virtual mainboard so it can not power off the system.
This also often happens with old Windows 2000 VMs.
You maybe able to work around this by letting redhat redetct the virtual hardware - maybe with enabled ACPI features ... don't know how this is called in redhat
