RFR : 8225345: Provide Cloud IAAS related info on Linux in the hs_err file

[Baesken, Matthias]

Hello  Alan ,   that  sounds like a good idea ;  we could have  a section  (output  probably guarded by  "ExtensiveErrorReports" )  with  

DMI information :
product_name: ....
product_version: ....
chassis_asset_tag: ....  
chassis_vendor: ...
bios_version: ...
bios_vendor: ....


( in the case of Azure we would get the strange   '7783-7084-3265-9085-8269-3286-77' ,   but otherwise it would look fine  [and also work for other IAAS like OpenStack ]  ) .

Best regards, Matthias
