What were you trying to do that didn't work?
Passthrough the host multipath as scsi-block device.
Execute MSFC test (Failover cluster validation) in Windows guest.
One of the guest hit io error
{"timestamp": \{"seconds": 1760164140, "microseconds": 741253}, "event": "BLOCK_IO_ERROR", "data": {"device": "", "nospace": false, "node-name": "host_disk", "reason": "Invalid argument", "operation": "write", "action": "stop"}}
The guest crashed after resuming the VM

2. Execute WSFC test
Expected results
The test may pass
Actual results
One VM gets paused due to io-error
It crashed after resuming the VM
