Are you getting an error, or does it not show in the UI?Hi Greg, I don’t know what’s happening. On 4.2 I was using Broadwell IBRS (only), and now I’ve got an error message when selecting Broadwell IBRS SSBD:<attachment.png>Host CPU type is not compatible with Cluster Properties.I checked the flags and yes, I can’t find SSBD:Flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 sdbg fma cx16 xtpr pdcm pcid dca sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm 3dnowprefetch epb cat_l3 cdp_l3 intel_ppin intel_pt ibrs ibpb stibp tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 hle avx2 smep bmi2 erms invpcid rtm cqm rdt_a rdseed adx smap xsaveopt cqm_llc cqm_occup_llc cqm_mbm_total cqm_mbm_local dtherm ida arat pln pts spec_ctrl intel_stibpI don’t know whats happening but I was thinking that my CPU supports this flag:Model name: Intel(R) Xeon(R) CPU E5-2620 v4 @ 2.10GHzAnswering my own question: I think I need a BIOS update.

There has been lot's of discussion about that this week. I had same
problem with Opteron G3->Epyc conversion. There steps were suggested
to me and they worked and you problem is similar:+1, thanks
- set HE global maintenance mode
- set one of the hosted-engine hosts into maintenance mode
- move it to a different cluster
- shutdown the engine VM
- manually restart the engine VM on the host on the custom cluster
directly executing on that host: hosted-engine --vm-start
- connect again to the engine
- set all the hosts of the initial cluster into maintenance mode
- upgrade the cluster
- shut down again the engine VM
- manually restart the engine VM on one of the hosts of the initial cluster
- move back the host that got into a temporary cluster to its initial cluster
As first step I would add that you create new cluster which already
has 4.3 level and CPU Type you want so already can check if cluster
accepts nodes.
