Some of you must have esxi5.5.
I think there is no patch for spectra. If I am correct?
What do you do with that?

Yes, there are....Patch - ESXi550-201709101-SG*

see here

BUT, be warned here VMware/Intel have pulled some of the patches, and you will also need to discuss/look at Vendor support for your server, and when it also has a Firmware Update for your BIOS and Microcode Update for Host Server.

To successfully patch, you will need to Patch

1. Host Server BIOS
2. Host Server CPU Microcode
3. Host Server ESXi Hypervisor
4. Guest Machine Virtual Machines

This was also discussed here

(but please note, things have been updated since)

Thank you Andrew,  Question about 2 in your  list above . Is it  cpuid.7.edx = "----:00--:----:----:----:----:----:----"    as on the KB article below

I already applied BIOS update and ESXi patch which includes ESXi600-20180140 BG !!
We have not applied the OS patch yet.
I wonder whether we have to add that line in the /etc/vmware/config in our case since we applied that patches for our E5-2600 -V4 CPU host.

This question is to deal with ESXi 5.5, not ESXi 6.0!
