Prepare a hypervisor on the host
Keep this record private. Do not include passwords or serial numbers.

Your actual setup, if available:
Installation allowed by owner or administrator:
Host OS and release:
CPU architecture (x86-64 / ARM64 / other):
Installed RAM / currently available RAM:
Free storage / planned VM folder:
Vendor-supported host and guest combination:
Virtualization support/status, if shown:
Hypervisor name / full version / installer filename / official URL:
Current license and download requirements:
Result: manager opens / installation deferred, with reason

No-install reasoning cards (fictional):
A: Owned Windows 11 x86-64 laptop; installation allowed;
   16 GiB RAM, 7 GiB in use, 120 GiB free storage.
   Hypervisor compatibility and current installer have not been checked.
B: Managed ARM64 laptop; installation prohibited by its administrator.
   No permission to change the host or create a guest.
For each card, decide the next allowed action and what still needs checking.
Separate a host hypervisor installer from the future guest's Ubuntu ISO.

Conceptual order, not recorded screens:
Inspect host and permission -> choose compatible host installer ->
install on host -> open VM manager -> later create and install a guest.

Separate question case:
An empty VM manager has no guest OS yet.
Where must the hypervisor installer run?
Answer format: host or guest.
