There is a very low probability that hitting physical NVMe disk
hardware critical warning case, it's hard to write & test a monitor
agent service.
For debugging purposes, add a new 'smart_critical_warning' property
to emulate this situation.
The orignal version of this change is implemented by adding a fixed
property which could be initialized by QEMU command line. Suggested
by Philippe & Klaus, rework like current version.
Test with this patch:
1, change smart_critical_warning property for a running VM:
#virsh qemu-monitor-command nvme-upstream '{ "execute": "qom-set",
"arguments": { "path": "/machine/peripheral-anon/device[0]",
"property": "smart_critical_warning", "value":16 } }'
2, run smartctl in guest
#smartctl -H -l error /dev/nvme0n1
=== START OF SMART DATA SECTION ===
SMART overall-health self-assessment test result: FAILED!
- volatile memory backup device has failed
