In every release of Hyper-V Microsoft has improved support for Linux.
The support of Linux is being improved in Hyper-V 2012R2 with the following features:
- Linux Synthetic Frame Buffer driver – Provides enhanced graphics performance and superior resolution for Linux desktop users.
- Linux Dynamic memory support – Provides higher virtual machine density/host for Linux hosters.
- Live Virtual Machine Backup support – Provisions uninterrupted backup support for live Linux virtual machines.
- Dynamic expansion of fixed size Linux VHDs – Allows expansion of live mounted fixed sized Linux VHDs.
- Kdump/kexec support for Linux virtual machines – Allow creating kernel dumps of Linux virtual machines.
- NMI (Non-Maskable Interrupt) support for Linux virtual machines – Allows delivery of manually triggered interrupts to Linux virtual machines running on Hyper-V.
- Specification of Memory Mapped I/O (MMIO) gap – Provides fine grained control over available RAM for virtual appliance manufacturers.
In a nutshell what this means is that you can have dynamic memory working on Virtual Linux Machines, perform live backups of the Linux VM’s without pausing or interrupting the activity of the servers, dynamically enlarge VM disks without interrupting the VM and more.
This basically means that you can run Linux VM’s in a hyper-V environment with the same features as Windows provisioned VM’s.
I can’t wait to see all those virtual appliances out there being customised for Hyper-V.
