Phoronix: Microsoft Increasing Linux Security On Hyper-V With VTL/VSM Support

Microsoft engineers continue to work heavily on enhancing the Linux support for Hyper-V considering that in the Azure public cloud at last report was more than 50% of their VMs running Linux. Microsoft has continued implementing more Hyper-V features within the Linux kernel and their latest is working on Virtual Trust Level (VTL) integration as part of Virtual Secure Mode (VSM) handling...

Obviously I doubt it...as one should.
