Wczoraj Microsoft na konferencji TechEd North America 2013 ogłosił sporo nowych funkcji związanych z wirtualizacją, jakie się pojawią w nadchodzącym Windows Server 2012 R2. Tym postem chcę wam przybliżyć te wspaniałe nadchodzące wirtualizacje nowości:

  • 2nd generation VM – nowa generacja maszyn wirtualnych bazująca na UEFI – brak emulacji urządzań, rozruch z wirtualnych kontrolerów SCSI lub syntetycznego kontrolera sieci (PXE boot >100 MBit) oraz bezpieczny rozruch. Aby skorzystać w w/w nowości, system operacyjny gościa będzie musiał być 64-bitową edycja Windows 8, Windows Server 2012, Windows 8.1 lub Windows Server 2012 R2.
  • Automatic Guest Activation – maszyny wirtualne automatycznie zostaną aktywowane, jeżeli host Hyper-V jest aktywowany jako edycja Datacenter.
  • Cross-Version Shared-Nothing Live Migration – Live Migration z Windows Server 2012 do Windows Server 2012 R2 (łącznie z funkcjonalnością już dostępna od Hyper-V 2012 – mowa o Shared-Nothing Live Migration, która pozwala na dokonanie migracji na żywo na inny serwer Hyper-V bez żadnej współdzielonej przestrzeni – nie jest wymagany żaden klaster).
  • Hyper-V Recovery Manager – umożliwia łatwy failover chmur prywatnych do innego centrum przetwarzania danych. Funkcja integruje System Center 2012 Virtual Machine Manager oraz technologię Hyper-V Replica z Windows Server 2012. Dzięki temu można zbudować automatyzację dla failover lub odzyskiwania pomiędzy centrami danych.
  • Hyper-V Replica improvements – będzie można replikować maszyny wirtualne nie tylko w schemacie A-B/A-C ale również w A-B-C oraz w 3 różnych czasach RPO co 30 sekund, co 5 minut oraz co 15 minut. Dodatkowo funkcja Hyper-V Replica została poprawiona w kontekście skalowalności oraz wydajności.
  • Linux Guest OS support enhancements – wsparcie Dynamic Memory oraz kopie zapasowe “na żywo” maszyn z systemem Linux.
  • Linux Video Driver – doświadczenie wideo na maszynach wirtualnych z Linux podobne do tych co z Windows.
  • Live Migration Compression – ruch Live Migration będzie kompresowany po stronie hosta Hyper-V przed wysłaniem, co skutkuje znaczną redukcja czasu migracji – nawet do 50% szybciej!
  • Live Migration over SMB Direct (RDMA) – Live Migration może bezpośrednio użyć SMB 3.0 co w praktyce umożliwia wykorzystanie technologii Remote Direct Memory Access (RDMA), która umożliwia jeszcze szybsze Live Migration.
  • Live resizing of VHDX – możliwość rozszerzania oraz zmniejszania plików VHDX “na żywo”.
  • Live VM Cloning – możliwość klonowania działającej maszyny wirtualnej “na żywo”.
  • Live VM Exporting – możliwość eksportowania działającej maszyny wirtualnej “na żywo”.
  • Shared VHDX – plik VHDX może być współdzielony pomiędzy dwiema maszynami wirtualnym za pomocą wirtualnego kontrolera SCSI. Dzięki temu w prosty sposób będzie można stworzyć współdzieloną przestrzeń, potrzebną do budowy klastrów na poziomie systemów gościa maszyn wirtualnych. Eliminujemy potrzebę użycia iSCSI lub Virtual Fiber Channel.
  • Storage Quality of Service (QoS) – Limitowanie IOPS per konkretna maszyna wirtualna.
  • VM Connect – użycie RDP do interakcji z maszyną wirtualną za pomocą VMBus (wirtualna szyna komunikacyjna pomiędzy hostem, a maszyną wirtualną), co umożliwia wykorzystanie możliwości RDP takich jak współdzielony schowek, przekierowanie audio, przekierowanie folderów, smartcard, USB Pass-through, etc.
  • Windows Azure compatibility – Windows Azure używa Hyper-V w Windows Server 2012 jako platformę wirtualizacji, co daje kompatybilność uruchomionych maszyn wirtualnych on-premise w Hyper-V, a Windows Azure.

Dzieje się!

At the beginning of the January 2013, Microsoft Open Technologies announced new service for Windows Azure IaaS – VM Depot. What is VM Depot? It’s a community-driven catalog of preconfigured operating systems, applications, and development stacks that can easily be deployed on Windows Azure. Using VM Depot and Windows Azure, developers can create and share images of Linux-based virtual machines, and share details on their experiences using those images.

When service started, one way to provisioning VMs from VM Depot was using Node.js. Now, you can use Windows Azure Management Portal to do this 🙂

When you select the Virtual Machines tab, you will now see an option to BROWSE VMDEPOT:

WindowsAzure-VMDepot001

Under BROWSE VMDEPOT you are presented with a full list of available images:

WindowsAzure-VMDepot002

You cane also prepare own Linux-based images for Windows Azure and publish it to VM Depot Community 🙂

WindowsAzure-VMDepot003Have fun!
