Considerations for Windows Server
2019 guest operating system
A generation 2 virtual machine running Windows Server 2019 may remain at the bootloader screen for OS
selection when restarting the virtual machine.
This issue has been fixed in the cumulative updates for Windows Server 2019(
KB4476976 or later). Please apply
KB4476976 or later.
For information on the latest cumulative update, refer to "

history".
SR-IOV (Single Root I/O
Virtualization) Feature
The SR-IOV feature is currently not supported on Express 5800 Series
servers.
Considerations for Exporting Virtual
Machine
If you export a virtual machine with a physical CD/DVD drive allocated to it, the virtual machine
settings for CD/DVD drive may show "Physical Drive Not Found" when you import the data. (The import
itself is done successfully.)
If a physical CD/DVD drive is allocated to the virtual machine, cancel the allocation before exporting
the virtual machine.
Restriction on Using Generation 2
Virtual Machine
The following issues will occur when you install Windows Server 2012 on a generation 2 virtual machine.
- You cannot use the physical keyboard until the installation is done.
- You cannot use the physical keyboard in Windows Recovery Environment(Windows RE).
When you need to enter a product key to install a guest operating system, click on the keyboard icon on
the right side of the input box to use the software keyboard.
When you need to specify the partition size, adjust the size using the UP/Down allows on the right side
of the input box.
Considerations for Executing Sysprep
on a Virtual Machine
The following issues will occur if you execute Sysprep after installing the Hyper-V Integration Services
on guest operationg systems.
Issue:
The following types of guest operating systems do not boot.
- Windows Server 2012 on a generation 1 or generation 2 virtual machine
Take ether of the following workarounds if you execute Sysprep on those
guest operating systems.
- Applying KB2779768 to the guest operating
system before executing Sysprep.
- Applying KB2822241 to the guest operating
system before executing Sysprep.
-
- Using /mode:VM option when executing Sysprep.
