I am a long time user of VMWare Workstation and am about to update my very outdated and now expired certifications.

 

I chose VMWare Workstationa again due to nested VM support which HyperV still doesn't provide. I created all my VMware vms fine including a nested VM for HyperV. So far this  worked as I created a role for HyperV and successfully created both Windows 10 and Server 2012 R2 base images.

 

I need Server 2003 for a gateway/router between my domains and subnet tests like I normally use. 

 

THe problem is EFI is enabled by default and I do not know how to shut it off. I turned off secureboot but I get EFI ... book failed. EFI scisi Disk etc. I tried adding my own virtual hard disks and cdroms and still did not work.

 

Can hyperV run older operating systems?

Make sure you select Gen 1. Gen 2 is EFI only.

Gen1 Hyper-V supports OSes back to (surprisingly) Windows 2000 forward to Windows 10 - including (egad) OS/2-eComStation, most Linux distributions, any BSD or derivative, etc.  (It even supports Android - which Visual Studio 2013 and 2015 leverage as part of the optional-but-free mobile development support.)  I haven't had ANY reason to use Gen2 Hyper-V support yet - though I could with 2012R2 and Server 2010/Windows 8 or later VMs; Gen1 still supports the same OSes - therefore, at least for me, what is the point of mixed-generation VMs?

The only real sting in the tail with Hyper-V is that - on the Intel side - you need Core i-series of any generation OR PentiumG/CeleronG third-generation or better; surprisingly, AMD has better Hyper-V support the further back you go than Intel does (all FX series CPUs, all Fusion APUs, and pre-FX CPUs back to Athlon II, including their mobile variants - remember, Baby Pavilion is driven by the Athlon II Mobile, and it's my mobile development platform, with the advantage of being portable itself).  Lastly, 2012R2 does NOT require EPT support to leverage Hyper-V - however, Server 2016 requires EPT support to even be installed.  Still, as I said, that's the only real sting in the tail with Hyper-V at all.

I happen to like installing Server 2012 in two minutes or less, and VMs that's reboot in 12 seconds (reboot, not boot).  But hey, stay legacy if you want. ;)

In a mixed environment, sure, you kinda have to use GEN1. But in a pure Server 2012 R2 environment, there are plenty of reasons to use GEN2.

    • Zed 1.7.2 has landed with updated OpenCode models, bug fixes and other improvements by David Uzondu Zed 1.7.2 recently landed on the stable release channel, bringing a host of AI-related features including automatic context compaction and settings-based skill management, along with other things like better Markdown preview rendering and custom git commands in the graph view. Starting with the AI stuff, the developers introduced "/compact", a command that basically summarizes your conversation history on demand. This tool prevents your active chat window from hitting token limits by compressing older parts of the dialogue into a brief overview. In addition to that, the team relocated skill management to the settings UI, improving how the application communicates errors regarding those skills, and updated the OpenCode model roster to support DeepSeek V4 Flash, MiniMax M3, Qwen 3.7 Plus, and Nemotron 3 Ultra Free. External agent users can also monitor context window cost metrics and delete individual sessions directly from their history. Right-clicking ref labels in the git graph now opens a context menu that runs different actions against selected targets, kind of how VS Code does it. Here are some of the bug fixes this new release brings: The active agent fails to auto-select when creating a new git worktree. A scrollbar unexpectedly appears on wrapped code blocks in the agent chat. Collapse indicators for project headers appear when performing sidebar searches. Bracketed ellipsis title prefixes fail to show the ellipsis icon properly. Project icons render incorrectly in the recent projects picker. Diff hunk controls appear inside non-editable commit view multibuffers. The software update button hangs indefinitely on the downloading stage. Restoring an agent terminal in a remote project triggers a sudden crash. Splitting a pane that contains an active commit view causes a crash. Linux Wayland freezes when trying to read the clipboard from laggy external apps. Zed is a "newish" code editor trying to break the massive stronghold VS Code has on the developer community. Funny enough, the editor was created by former GitHub employees who worked on the Atom text editor (which Microsoft killed in 2022, several years after it bought GitHub). The project officially hit version 1.0 back in April, introducing platform parity for Windows and Linux alongside deep support for DeepSeek-V4-Pro.
    • 26H2 absolutely will support ARM Windows just not on devices that came with 26H1. This is evident by the fact I am running 26H2, which on my MacBook Neo and Surface Pro 12 (inch), within a VM.

    • The FIFA World Cup is not US centric.
    • It’s amusing how Microsoft is pushing IT admins as if this was a major, game-changing update. In reality, it’s just an enablement package that bumps the build number, which is disappointing compared to the more substantial 22H2 and 24H2 releases. Technically, 25H2, 26H1, and the upcoming 26H2 are essentially the same, differing only in support schedules. They could have included the Windows K2 improvements here, but chose not to. The era of Windows being in the backburner continues, and this 26H2 release feels like an afterthought. Shame, Nadella, shame.
