From 4.0 architecture family was renamed in script 04_00_0080_rename_architecture_family. So 'HotPlugCpuSupported', 'HotUnplugCpuSupported', 'HotPlugMemorySupported', 'HotUnplugMemorySupported', 'IsMigrationSupported',  'IsMemorySnapshotSupported' and 'IsSuspendSupported' are all in db with x86 not x86_64. In my point of view nothing wrong with that particular line in [1].

Could be that somewhere in code is not used architecture family, but host architecture, when asked for value of this ConfigValues. But that would throw exception even before my patch, because '{"x86:"true","ppc":"true"}' was default value for HotPlugMemorySupported.

I see a code path where the cluster arch can be set to x86_64 - it is always executed for external VMs (imported from external provider or unmanaged). It does not happen all the time, it is only a fallback if the arch type is not known/reported etc.

@Alexander: by any chance, was this VM an unmanaged one? Or imported? In logs you should find something like:

"Illegal architecture type: {}, replacing with x86_64" or "null architecture type, replacing with x86_64, {}".

Also, if you create a new VM, can you start it?

Yep, in particular line 23 of FeatureSupported.java.

I meant the caller of the method on this line. Do you have it in the trace so we can see who passed x86_64 as arch ?

It looks a lot like introduced here: https://gerrit.ovirt.org/#/c/81464/

@Mirka: what you think?
