    ESXi 6.5 vCPU bug, sockets: 1.33333333

    LordNicoll Lurker

      While attempting to change a VM from 6 cores, 1 socket, to 8 cores, 2 sockets, I get this bizarre error, After saving the config, the VM wouldn't start, and when I looked, it had defaulted to

      8 cores, 1 cores per socket, sockets: 1.3333333, from being at

      8 cores, 4 cores per socket, sockets: 2


      The server is a HP ProLiant DL380 G7 with 60GIB of RAM and dual Xeon X5670's. ESXi is installed on a microSD card in an SD Card adapter, but the adapter has a lock feature, but doesn't label which is locked, could that be the cause? I've changes the RAM allocation a lot in the same time and successfully passed a PCIe device to another VM however, so I'm not that sure. The host's OS is ESXi 6.5.0 (Build 4887370)


      The error is "Failed to power on virtual machine [VM name]. Module 'CPUID' power on failed. Click here for more details."
