Description:
'<vmname>' was reset because an unrecoverable
error occurred on a virtual processor that caused a triple fault. If the
problem persists, contact Product Support. (Virtual machine ID )"VMware has a good Knowledge Base artice about this issue: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2073791
But, it seems that this issue is also affecting Hyper-V 2012 R2 hosts.
I have had this problem on both platforms. At least Dell has published a BIOS upgrade that fixes this issue, quote from R720 BIOS 2.2.3 release notes:
"What’s New
===========
* Updated Intel Xeon processor E5-2600 V2 product family microcode to 427.
Fixes
======
* Corrected an issue where a complex sequence of internal processor events may result in unexpected page faults or use of incorrect page translations If EPT (Extended Page Tables) is enabled. Due to this erratum a guest may crash or experience unpredictable system behavior."So, if you run in to this problem, look for BIOS update from your HW vendor!
