Hi there,
Thanks for the help. To your questions:
1. Currently we are still using a trial version license.
2. The system is of a fresh ESXi 6.7 installation, and not updated from the lower ones. this is the message I got if was to run uname on it :
" VMkernel ... 6.7.0 #1 SMP Release build-8169922 Apr 3 2018 14:48:22 x86_64 x86_64 x86_64 ESXi "
3. This vm was originally created with 16-CPU, and started without any problems. But today, if I was to downsize it to 2-CPU, I still got this failure.
Thanks,
Jack
