![]() ![]() Ok, some of that CPU pool is consumed by other VMs (and reserved by the kernel?) and thus cannot be reserved by new VM.ĥ) Powering on a VM configured with 5 cores and 16000 MHz CPU reservationĦ) Powering on a VM configured with 4 cores and 12800 MHz CPU reservation Setting affinity explicitly choosing HT cores did not change anything.Ĥ) Powering on a VM configured with 6 cores and 19200 MHz CPU reservation It wants reservation to be set exactly to number_of_cores * nominal_processor_frequency. HT cores are not counted in host CPU resource pool?ģ) Powering on a VM configured with 8 cores and 19200 MHz or any other less than 25600 MHz CPU reservation (16000, 12800 etc). ![]() vmx file I still unable to power on a VM with an error:įailed - The amount of CPU resource available in the parent resource pool is insufficient for the operation. That seems to come from 6 * 3200 = 19200 and that is unexpected.Įven if I set 25600 MHz reservation in. It clearly comes from 8 * 3200 = 25600 so it seems reasonable and exactly what I expected after reading VMware Resource Management Guide.Ģ) Setting CPU reservation to 25600 MHz only to discover that I'm unable to set it as I have only 19200 MHz available for reservation. ![]() Need full CPU reservation: 25600 MHz (measured) or nominal processor frequency. The problem is that I'm unable to set more than 4 cores to High Latency Sensitivity VM.ġ) Powering on a VM configured with 8 cores and no CPU reservation.įailed - Invalid CPU reservation for the latency-sensitive VM. Total amount of assigned cores to other VMs is 4. The goal is to set up new VM with 8 cores (8 logical cores) there.Īll other VMs on this host have no CPU reservations. My host runs ESXi 6.7 on Intel Xeon CPU E5-1650 3.2 GHz, it has 6 cores and HT enabled, so 12 logical cores. I'm trying to setup a VM with high latency sensitivity. ![]()
