Hello,
Thank you for posting in Microsoft Q&A.
Based on the description, I understand your question is related to Windows 11 24H2.
Right-click on the H3C Cloud Lab executable. Select Properties > Compatibility tab. Check Run this program in compatibility mode for and select Windows 10. This will run H3C Cloud Lab in Compatibility Mode.
The version of VirtualBox bundled with H3C Cloud Lab might be incompatible with Windows 11 24H2. Try installing a different version of VirtualBox (e.g., VirtualBox 6.1 or 7.0) and configure H3C Cloud Lab to use it.
Visit the H3C Cloud Lab official website to check if there are any updates or patches available that address compatibility with Windows 11 24H2.
Have a nice day.
Best Regards,
Molly
