Remote Desktop feature dont work

[st3rven]

Describe the bug

Hi! I’m just starting to use Exegol and I’m having trouble using the remote desktop option. The port appears to be listening on my host machine, but I can’t access the service.

Environment

• Host OS: MacOS
• Docker Destop: 4.31.0
• Exegol version: 4.3.4
• Image: nightly - v.53b086e1

Evidence:

• Container start

• Curl from host

• Host: port is listening

• Container: Any service is listening

Hello

Can you check if the virtual desktop process are running ? Run ps -faux inside your container to check. If there is none, try to run desktop-start and screenshot the output to see if there is any error

Thank you

Hi @Dramelac,

the process is not running, and when I tried to execute the mentioned command I receive the following error message: assertion failed [rem_idx != -1]: Unable to find existing allocation for shared memory segment to unmap (VMAllocationTracker.cpp:745 remove_shared_mem)

[cdrmx]

Hi all

Same issue with this configuration :

Host OS: Fedora
Exegol version: 4.3.4
Image: full - v.3.1.4
Firefox: 128.0

Test the same command :

Can't access I try to recreate workspace.... Nothing

Thank's for your help

Unable to find existing allocation for shared memory segment to unmap

Hello @st3rven I have found this post with the same kind of error: https://forums.docker.com/t/unable-to-find-existing-allocation-for-shared-memory-segment-to-unmap/139868 You can try to fix it by increasing the virtual disk limit in docker desktop

Hello @cdrmx we've heard of a bug with fedora and the desktop feature, we're investigating.

[st3rven]

Hi @Dramelac The error persists even after updating to 240 GB. My configuration.

Hi @Dramelac The error persists even after updating to 240 GB. My configuration.

We were unfortunately unable to reproduce. I'm not sure where the error is, either from vnc service or from docker desktop. Maybe try to use orbstack instead of docker desktop to see if the bug persist.

[st3rven]

I installed OrbStack and migrated the container (without creating a new one), and I don’t know what kind of black magic it does, but it works! So, the most logical conclusion is that the issue lies with Docker Desktop. I guess it’s just another one of life’s mysteries.

[Dramelac]

Yeah docker desktop have a lot of weird bug ^^' Enjoy your desktop ! I'm closing this issue because it was related to a desktop bug on Docker Desktop but, (@cdrmx) regarding fedora, a patch will be deploy with the next nightly image !
