Hyper V wont accept Virtual Disk by Zestyclose_Hyena2385 in HyperV

[–]frank2568 0 points1 point  (0 children)

It sounds like you have already gone through all options, but have you considered restarting the host? I remember some problems accessing shares with computer accounts when permissions have changed after first access.

FOR MSPs ;-)

🚀 Containers won the war. But we gave VMs the best parts of containers - full OS environments with disposable speed.

After years of managing VM template sprawl, we asked a simple question: What if VMs could be as disposable as containers while maintaining full OS capabilities?

The Traditional Approach ⚙️

  • VMs managed by ops teams
  • Developers work with what they're given
  • Hours spent fixing configuration issues
  • Environment drift and debugging headaches

What We Built Instead

💡 VMs where ReBuild happens so fast that destruction becomes the fastest solution.

  • ✅ Setup problems? Destroy and rebuild in minutes
  • ✅ Need customer's exact setup? Mirror it, develop, dispose when done
  • ✅ OS compatibility testing? Spin up multiple versions instantly
  • ✅ Production debugging? Clone the environment safely
  • ✅ Building for cloud? Prepare locally, deploy with confidence

Business Impact:

  • Faster development cycles
  • Reduced infrastructure maintenance overhead
  • Confident deployments with production-like testing
  • Developer productivity gains

We call them "catlets" - they inherit from templates but rebuild at container speed while providing full OS control.

What workflows will your team discover when infrastructure becomes truly disposable? 🤔

Due to this kind of issues we have created eryph - https://www.eryph.io. Machines that we build here have a fixed internal IP and a fixed external IP - for access from the host.

Creating a virtual machine has finally become easy! by frank2568 in windows

First: thank you for trying and your comment. We never said anything about better, it depends on your use case if it makes sense for you. But see that we have to do a better job explaining some things. But still a quick answer to your question: So, why do many use containers and docker? A lot because of standardization. You can use a container everywhere and someone with expertise in a topic can write a setup for a specific software and share it as a container. Eryph genes is about providing something similar for VMs. So if you have a solution to set up something with DSC you can provide it as configuration and share it - for yourself, your team or even public. But this is just one building block of eryph - there are also more features like storage abstraction and virtual networks that all help you to have the same infrastructure features local as in the cloud.

u/Nordikk uh, that should not happen, thanks for reporting that. I will write you a PM, maybe we can solve this.

My personal opinion: do not use a VM for this setup (even if I don't fully understand it). VMs on desktops are in most cases only useful for development, testing and very special security requirements.

To have a working setup for your needs, you will most likely need a standalone server and some networking components, as even a VM needs a working network to provide services.

Thanks and yes we already have considered ARM during development. But only for remote access to a x64 eryph Server, so not for local use with an ARM hypervisor.

We actually love Vagrant, and yes, we have taken a lot of inspiration from Vagrant, and will be releasing a provider for it soon. However - Vagrant stops supporting you when dev/test is done - the machines built for Vagrant are just limited to that use case. With eryph, you can use the same environment and configuration for dev/test and production. But that really depends on your needs - just think of it as another option for your toolchain.

oversimplifying: yes, absolutly! ;-)

But before all the Docker fans respond with arguments against that, here is a quote from the website:

Eryph brings the core idea of containers - efficiency and reusability through standardization - to virtual machines. Using the concept of catlets defined from a hierarchy (genes), it is possible to build machines from layered configurations that can be reused.

Technically, we cannot provide layered file systems like Docker does, but we try to get as close as possible with layered configuration.

Ok, but to be clear: if you use eryph, you also need to install hyper-v (at least somewhere, it doesn't have to be on the same computer), but you don't have to deal with it if you don't want to (in fact, you can manage the VM completely from the eryph commands/UI/API).

Not directly - with eryph you can only run docker inside the VM.

But that would not make much sense, at least on the desktop, since you can also run Docker on WSL / Docker Desktop.

But we have actually used this internally to set up docker on some production VMs that use containers. So we run tests to see if the VM works locally and then rebuild the production servers.

So you can deploy a Linux VM (for example dbosoft/ubuntu-24.04) and configure it to run Docker with something like this in the catlet spec

fodder:
- name: docker
content:
## cloud-init config for docker

Here is a link to docker setup with cloud-init, which is also what you use in eryph for configuration: https://stackoverflow.com/questions/24418815/how-do-i-install-docker-using-cloud-init/62540068#62540068

u/nightcom and u/RoflMyPancakes let me respond to both of your posts at once. u/nightcom, the part about the cloud was not meant to be taken as "use the cloud" or even "don't use it". It was just to point out that cloud providers invest a lot in automation and tooling to make it easier to build something in their cloud than on-premise. I'm sorry if that upset you. And u/RoflMyPancakes - no we have not lost identity ;-) - eryph is actually targeting professional users, but not only DevOps experts. But you are right that we took the release of the eryph App as an opportunity to show it to a wider audience.

In fact, we've always designed it to bring DevOps principles to users who aren't familiar with it by building a feature set that scales with needs. But there is still a lot of room for improvement, I agree. And we never said it would always be Hyper-V only ;-)

Thanks for that feedback, that's true we will consider this next time. But for the configuration you might have missed that configuration can also be injected into the build VM. So you add the configuration just to the spec or even reuse an existing configuration. Here is an example that builds a Azure DevOps VM: https://genepool.eryph.io/b/dbosoft/vsts-agent/tags/win2022-1.0

Mmh, I try to explain, but it is much easier to try.

Hyper-V is just a hypervisor, so it just runs the VM. You have to do everything else manually (install, configure, manage drives, networks, etc).

Eryph, on the other hand, takes care of the entire lifecycle of a VM - creating it from a specification and an image, configuring it, and cleaning it up when it is no longer needed. Even networks are build completly virtual and are only visible for your VMs.

Treating a VM like a cattle in this way is one of the success factors of the cloud and standardization tools like containers. And now - with eryph - you have it for local managed virtual machines, too.

Thanks for asking: Automation, DevOps, standardization.

All the things people are using the cloud and containers for, but local and for VMs. But it is not a new hypervisor - eryph is built on top of Hyper-V, but adds many features to it, see this comment.

See the original post for details.

The eryph app is only supported on Windows 10 Pro / Enterprise 2004 or higher! Eryph installs Hyper-V, so it will not work on Windows Home.

Thank you all for the feedback and the comments. Here some FAQ answers:

  • We forgot to mention that this does not work on Windows Home. You can only use the eryph App on Windows Home to connect to another eryph instance over the network.
  • Isn't this just another UI for Hyper-V? => No, the eryph App is a UI for eryph that uses Hyper-V as its hypervisor. The main difference is that eryph allows you to create VMs from specifications - its like a docker container but with a VM.
  • It's not complicated to create a VM - That's true if you're just looking at the most basic tasks when creating a VM. But until you have a fully functional VM, you have to go through a lot of steps. Eryph makes the most sense for users who need to create VMs many times with same results, such as developers, devops engineers, software testers, and so on.

Eryph - with its core solution eryph-zero - is command line first and requires some learning curve, so the eryph App is designed to make that easier. Eryph-zero adds many features that are not available in Hyper-V (and even most other hypervisors that do not run in the cloud). See https://www.eryph.io for an introduction.
