HDD UUID changes when passed-through from server to VM.
I performed HDD passthrough via the following command on PVE 6.2-4.

root@pve:~# qm set 140 -sata1 /dev/disk/by-id/ata-WDC_WD4003FZEX-00Z4SA0_WD-WMC5D0D5H090 update VM 140: -sata1 /dev/disk/by-id/ata-WDC_WD4003FZEX-00Z4SA0_WD-WMC5D0D5H090 root@pve:~# qm set 140 -sata2 /dev/disk/by-id/ata-WDC_WD4003FZEX-00Z4SA0_WD-WCC5DAJC41SR update VM 140: -sata2 /dev/disk/by-id/ata-WDC_WD4003FZEX-00Z4SA0_WD-WCC5DAJC41SR

In the VM when I view the disks by-id I get the following UUIDs instead:

root@omv:/dev/disk/by-id# ls ata-QEMU_DVD-ROM_QM00003 ata-QEMU_HARDDISK_QM00009 scsi-0QEMU_QEMU_HARDDISK_drive-scsi0-part1 ata-QEMU_HARDDISK_QM00007 ata-QEMU_HARDDISK_QM00009-part1 scsi-0QEMU_QEMU_HARDDISK_drive-scsi0-part2 ata-QEMU_HARDDISK_QM00007-part1 scsi-0QEMU_QEMU_HARDDISK_drive-scsi0 scsi-0QEMU_QEMU_HARDDISK_drive-scsi0-part5

I assumed that I would see "native" (?) UUID vs. Qemu-xxx

Any concern with this or is this expected and not an issue?
