-restart VM

=>Nevertheless no new hard drive in my Windows server guest

NB : harddrive is SSD nvme on PCIExpress,source dev=/dev/nvme0n1p1 (NTFS partionned).

How to add a harddrive/partition on Linux host (qemu configuration file) to be able to use it from my Windows Server Guest?

Thanks

My answer:


You made a virtual hardware change which requires the VM to be fully shut down (not just rebooted) before it takes effect.


BTW: For reasons of performance you should install the Virtio-SCSI driver in the guest OS, add the Virtio-SCSI controller to the virtual hardware, and convert your disks to use SCSI instead of IDE. And switch your virtual CDROM to SATA. Ideally you should have done this during installation; here is a guide for doing so.
