Michael Kelley Virtualizing Linux and FreeBSD Workloads on Windows Server Hyper-V INF335 A

Agenda Product goals Overview of Linux and FreeBSD Integration Services Supported Linux and FreeBSD distributions Linux and FreeBSD features LIS demo LIS hints and tips FreeBSD goals and status This session focuses on what’s available today!

Product Goals The reality: Your datacenter is heterogeneous You operate Windows workloads You operate workloads on Linux, FreeBSD, and other operating systems You just want it all to work Our goal: You can run Linux or FreeBSD in a Microsoft cloud as easily as you run Windows You get great functionality You get great performance It just works The foundation: Linux/FreeBSD runs great on Hyper-V On premises In the Microsoft Azure public cloud

Universe of Hyper-V Functionality Functionality Outside the Guest Super-fast live migration w/RDMA Software Defined Networking Software Defined Storage Storage QoS ……… Functionality Requiring Guest Cooperation Enhanced management Dynamic memory Live backup Generation 2 VMs ………

AIX, HP-UX Solaris SPARC Windows RT Yes No Emulated Devices No Hyper-V integration Limited manageability Limited functionality OK CPU, weak disk/net Solaris x86 Linux with no IS BSD with no IS Linux with IS FreeBSD with IS Windows with IS

0 Startup Memory Maximum Memory ❶ Hot-Add: Linux memory size increases ❷ Ballooning: Removes memory. Linux memory size is unchanged. Sum of dark blue doesn’t go below “Minimum Memory” ❸ Ballooning: Adds memory back. Linux memory size is unchanged

Available/Addressable memory in MB Actual Allocated Memory Output of “watch free –m” command in Linux bash shell. Memory tab in Hyper-V Manager

Linux Guest Hyper-V Host Guest VHD Hyper-V Storage User Space Kernel VSS Driver VSS Daemon Backup Utility File sys buffers ❶ Utility tells Hyper-V to start VM backup ❷ Hyper-V signals LIS inside the Linux guest to do backup steps ❸ LIS VSS components freeze the file systems and flush in memory buffers ❹ Hyper-V creates a VM checkpoint & tells LIS to unfreeze the FSs ❺ VSS in Hyper-V creates a snapshot of volume hosting the VHD Backup Storage ❻ Utility copies file- system consistent VHD from the snapshot
