Hi Samu,

virt-viewer is part of the virt-manager project.

Any way, searching the oVirt users list I didn’t find any virt-viewer issues or broken report.

You can report virt-viewer issues by accessing the upstream Gitlab virt-viewer repository at https://gitlab.com/virt-viewer/virt-viewer.

Remember to include your virt-viewer version, OS type and version, guest VM type you are trying to access, and step-by-step instructions on how to reproduce the issue.

Subject: [External] : [ovirt-users]Re: Fwd: React-based WebAdmin modernization for oVirt Engine

Hello 정하늘

This work looks amazing. I have a couple of questions:

Are you planning to address the VNC issue that we have going on? What I mean by that is the broken virt-viewer on Windows

Are you planning on sharing the work you have done with the developers of the upstream projects? If yes, are you also planning on sharing some of your builds with the public?

Br,

Samu

Hello oVirt maintainers,

My name is Jeong Haneul, and I'm an infrastructure engineer from South Korea.

First, I'd like to thank everyone who has contributed to oVirt over the years. I still provides virtualization solutions based on oVirt Engine, and we've relied on the project for a long time.

As upstream development has slowed, I started a personal modernization project to address some of the platform's technical debt.

So far, I've completed the following work:

Replaced the legacy GWT WebAdmin with a React-based frontend.
Completely removed the GWT frontend and the GWT-RPC communication layer.
Migrated client-server communication to REST APIs.
Upgraded the platform to Jakarta EE 11, WildFly 40, Java 21, and PostgreSQL 16.
Applied numerous security and dependency updates.

The project is still being validated, but most of the functionality is already working.

I would like to know whether there is still active interest in modernizing oVirt Engine. If so, I'd be happy to discuss the project, share my experience, and explore whether any part of this work could be useful for the community.

Please note that I'm not a professional software developer—I'm an infrastructure engineer—and I'm communicating in English using a translator. I appreciate your understanding.

Thank you for your time, and I look forward to hearing from you.

Best regards,

Jeong Haneul
