I have a very old stand alone ESXi host which was running image ESXi-6.7.0-20190402001 . I did the below two things
1.Update the latest patch https://docs.vmware.com/en/VMware-vSphere/6.7/rn/esxi670-202210001.html for version 6.7
2.Enable Side-Channel-Aware Scheduler, both were done via the ESXCLI as this was a stand alone host and were successful . After the mandatory reboot the server gets frozen on the 'enabling schedular' screen
vim-cmd hostsvc/maintenance_mode_enter
esxcli software sources profile list -d /vmfs/volumes/xxx/Patches/ESXi670-202210001.zip
excli software profile update --depot=/vmfs/volumes/xxx/Patches/ESXi670-202210001.zip -p ESXi-6.7.0-20221004001-standard
esxcli system settings kernel list -o hyperthreadingMitigation
esxcli system settings kernel set -s hyperthreadingMitigation -v TRUE
reboot
I disabled the legacy USB settings as per the below kb article https://kb.vmware.com/s/article/2077712
But I have no luck.
Any leads are appreciated
