You may not want to use all 3 or 4 (depends on settings at web set) VMs in KATA 4.1/5.0 SB. If one of the VM images is not installed, there will be SB self-diagnostics error at the KATA web-interface. Usually it's WinXP image that gets excluded.

KATA 4.1 sets

KATA 5.0 sets

Step-by-step guide

1. Execute the following command under root (this is example, you can choose VM images as it suits you)

   For 4.1

   apt-settings-manager set --merge /configuration/kata_scanner '{"sandbox": {"images": ["CentOS7_x64", "Win10_x64"]}}'

   For 5.0

   console-settings-updater set --merge /kata/configuration/product/kata_scanner '{"sandbox": {"images": ["Astra_x64", "Win7_x64", "Win10_x64"]}}'

2. Check that the settings have been applied: SB self-diagnostics error at KATA web-interface should disappear.
3. Check that SB processing works fine.

Consequences

You will see error under Administrator:

and under Security officer (in KATA 5.0)

No need to worry, as the workaround described has consequences.
