My VM takes 2-3 minutes before it gets to the TianoCore screen. I've read a lot about this being an issue with VMs with a lot of cores and RAM. However, I saw in a changelog for a recent version of UnRAID that it was related to Intel processors and that it had been resolved. Unfortunately, I am still having the issue with my Threadripper on the latest version of UnRAID. I couldn't find anything in the BIOS settings to help the issue and other solutions involve recompiling. Any ideas? Here is my VM XML:

I'm starting to think I need to submit a bug report. There doesn't seem to be anything I can do on my end. If anyone has any ideas, I'm all ears. Thanks.

Can you try as a test to lower the amount of ram, let's say to 8 Gb and see if it's faster?

I can but it will be a while. Like all the other cases I've read, it boots fine after the initial slow boot. It has to sit for a good long while before it happens again.

Just getting around to looking into this again. It does seem to boot faster with less RAM. I'm on 6.10.3 now.

I put this off for a while because I had more important things but I am still having this issue. I'm pretty sure it's just taking a long time to allocate all the RAM and other resources but using less RAM isn't really a solution. Anyone have any ideas? What I am currently seeing as the solution is to re-compile qemu with PREEMPT_NONE=y and CONFIG_VOLUNTARY_PREEMPTP=Y

Still an issue 2 years later. I also notice a correlation to amount of RAM, and I wonder if the system is trying to get contiguous blocks before starting the VM, but man, its slow...

While in this state it seems to also cause KVM to hang, and the UI just keeps "waving" it loading animation when trying to view VMs.
