Greetings.
I have a ESXi 5.5 environment with a Red Hat 5.10 operating system. The operating system worked fine until a few days ago. ESXi shows the error "The CPU has been disabled by the guest operating system. Power off or reset the virtual machine." I don´t know why my server shows the error if my environment was OK. Could be a kernel issue ? a operating system issue ?
Ideas ?
Thanks for the help.
Have a look here. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=200054...
Did you recently patch your VM? looks like when the Guest OS executes incorrect commands it can have a cpu disabled.

No, I didn´t patched my VM. I was thinking to update my kernel versión, but I´m not pretty sure about that because is a production environment. Some advice ? How I can verify these incorrect commands ? Im enabling kdump in RHEL, I hope to find the answer there.
Thanks for the help.
The guest has executed the HLT instruction with interrupts disabled. Are there any messages on the guest console?
Hello jmattson,
No messages in the guest, my virtual machine just remains bloqued. And the performance´s graphyc shows elevated procesing. No network, no nothing.
The CPU´s performance generally is low. The serverrunning well four days or a week. But crashes with no razon.
What CPU do you have? Do you have the latest microcode patches installed?
What CPU do you have?
I have a HP ProLiant BL465c G7 with CPU AMD Opteron 8-Core @ 2.4 GHz.
Do you have the latest microcode patches installed?
I don´t know. What do you mean about "microcode patches installed" ? Firmware updates ?
Thank you for all.

A 6100 series processor?

Microcode patches are distributed with firmware updates, but there are other avenues as well.
Please upload the vmware.log file for the VM as an attachment.
Check to make sure the VM power profile does not allow it to shutdown or sleep.
In the Hosts BIOS, make sure you have the power profile for for maximum performance. If this is not set, the hardware may put some cores to sleep and you will get a PSOD.
Thanks
