I have recently switch to kernel 6.14.0-2-rt from 6.12 LTS. After switching to 6.14.0-2-rt my virtual box stopped starting up the virtual machines.
To fix this I am downgrading my kernel. Is there any other patch available to fix this issue on 6.14.0-2-rt.

Is there any specific reason why you are using a real-time kernel? Real-time kernels are usually used for timing-sensitive tasks such as audio processing.
Also, was there an issue which made you switch from the linux612 LTS kernel? You might be better off sticking with that one, which will be supported until December, 2026.
Otherwise, linux615 is in the repos & can be installed via the manjaro-settings-manager or the command line:
sudo mhwd-kernel -i linux615
I’ve had issues when testing RT kernels and trying to use VirtualBox. Basically down to responsiveness of the host OS and things just hanging.
Honestly if there is no reason to use a HWE kernel, I’d stick with the known-working linux612.
If linux615 works fine for you, that’s good but not a long-term-support one, which means potentially more issues with the frequently “less-well-tested” next version.
The regular linux614 is EOL; who knows when the RT version follows suit (I don’t need RT versions).
In my case, I do check these mainline kernels out, but tend to stick with the best LTS ones for my machines; generally there’s better stability … also in my experience.
I recommend:
If an LTS kernel with a decent future lifespan works for you, keep it, at least as a reserve. Try out the HWE ones (mainline) but always keep a known good one (or two) in reserve. At least one LTS.
Thank you very much
I think you’re right i shouldn’t use RT kernel. Actually I was just testing if there were any additional feature or not and ended up with a VM issue.
Well, Thank you very much.
