[pve-devel] [PATCH qemu-server v7 1/1] fix #4957: add vendor and product information passthrough for SCSI-Disks
Hannes Duerr

Wed Jan 10 13:45:49 CET 2024
adds vendor and product information for SCSI devices to the json schema
and checks in the VM create/update API call if it is possible to add
these to QEMU as a device option
