Hi Everyone,

I am facing a weird issue in windows 10. After Installing the required virtIO Drivers, some of them show as "Removable Devices".

So far I have tried both methods of Manually installing the drivers as well as Bundling them within the VM Template using Sysprep.

Please Look into this, below is a screenshot for reference.

Seems like in qemu-kvm they implemented a hotplug flag in the pci declaration:

I don't think there are these options in the proxmox web gui.

Anyway in Windows you can add this batch at startup *Run as Administrator*:
Code: 
:: RUN AS Administrator
:: Virtio Baloon
reg.exe add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_1AF4&DEV_1002&SUBSYS_00051AF4&REV_00\5&2490727A&0&1808F0" /v Capabilities /t REG_DWORD /d 2 /f
:: Virtio Serial
reg.exe add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_1AF4&DEV_1003&SUBSYS_00031AF4&REV_00\5&2490727a&0&4008F0" /v Capabilities /t REG_DWORD /d 2 /f
:: Virtio SCSI
reg.exe add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_1AF4&DEV_1004&SUBSYS_00081AF4&REV_00\5&2490727A&0&2808F0" /v Capabilities /t REG_DWORD /d 2 /f
:: Virtio Ethernet
reg.exe add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_1AF4&DEV_1000&SUBSYS_00011AF4&REV_00\5&2490727A&0&9008F0" /v Capabilities /t REG_DWORD /d 2 /f
:: Nvidia
reg.exe add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_10DE&DEV_1FB1&SUBSYS_148810DE&REV_A1\4&23F93F77&0&00E0" /v Capabilities /t REG_DWORD /d 2 /f

With this VM config you didn't see any "Removable Devices" in Windows?

Can you post a screenshot of winver from the VM?
