we are facing some issue
we install new esxi vmware free 5.1.0 kernel 1065491
so after installation we found this message
" the system has found a problem on your machine and cant continue
vmware esxi requires the exceute disable/no execute cpu feature to be enable"
but after reboot the machine work fine
this is hp proliant g5 380 series server with raid 5 and 1 hotspare.
i found no issue running and installing VMs but as safe side advise how to trouble shoot or debug it.
