Please create a VHDX for compatible use with a Generation 2 Virtual Machine.

Current UEFI restrictions prevent this. The Gen 2 VM provides expanded capabilities including the use of 8+ network adapters without having to use Legacy Adapters

I second this; I already use 2 legacy adapters (with a max throughput of 30Mbit instead of 300Mbit), and I wilol need more adapters in the future, making the problem even bigger. And UEFT is just a must for a security product in 2022.

I did make a new topic here sharing that I managed to convert a 9.4.2p1 install from a gen1 to a gen2 UEFI machine (a VHDX drive container), however I witnessed absolutely no change in throughput performance nor any latency improvements, also no SR-IOV support and also no DDA (nic passthrough) support for Huper-V. However the install worked great on KVM with both SR-IOV and VFIO and did see a nice improvment in performance.

I personally feel Kerio should be aiming for at least the 5 series of Debian kernel which brings many additional drivers and numerous networking enhancements such as concise RDMA support and better KVM/Hyper-V virtualisation drivers/integration.
