config SCENARIO
string "ACRN scenario"
default "industry"
help
By specifying SCENARIO name, ACRN will load corresponding VM configurations
to build the hypervisor. Currently ACRN provides four reference scenarios:
- industry: Typical scenario for industry usage with 8 VMs: one pre-launched SOS VM,
one post-launched KATA VM, one post-launched RT VM for real-time control,
and up to five post-launched Standard VMs;
- hybrid: Typical scenario for hybrid usage with 3 VMs: one pre-launched Safety VM,
one pre-launched Service VM and one post-launched Standard VM;
- hybrid_rt: Typical scenario for hybrid real-time usage with 4 VMs: one
pre-launched RTVM, one pre-launched Service VM and two post-launched Standard VMs;
- logical_partition: Typical scenario that run two isolated pre-launched VMs
Other values are possible if a corresponding scenario has been created
under 'misc/vm_configs/scenarios/' in the source code.

hypervisor may relocate its symbols to where it is placed,
and thus the bootloader might not place the hypervisor at this
specific address.
Note that the addr demands 2M aligned, otherwise memory corruption
may occur.

help
By default, software workaround for Machine Check Error on Page Size Change is
conditionally applied to the models that may be affected by the issue. However,
the software workaround has negative impact on performance. If all the guest OS
kernels are trusted, this option may be set for performance.
config ENFORCE_TURNOFF_AC
