[SOLVED] Unable to boot on installation medium with Hyper-V Gen2

Hello everyone !

I have been running into a problem while trying to install an Arch Hyper-V VM.

My VM config is as follow :
     Secure Boot Disabled
     12Go RAM
     8 virtual processor

While trying to boot on the latest Arch ISO version (archlinux-2022.11.01-x86_64.iso), it loops into a black screen (I tried waiting 15+ mins to no avail)

However, if the number of virtual processors is reduced to 1, we finally see some text, but it is a kernel panic backtrace.
We'll get a console eventually, but it's frozen and the install medium is not even mounted. (screenshot here)
I also tried turning the TPU on/off but this doesn't change anything.

Is anyone able to reproduce this issue, and is there a solution to this ?

Is this your problem?

For Generation 2 machines, booting from a physical CD/DVD drive is not supported.

Hi MsFrips,

I've run into this problem as well and it looks to be an open issue: https://bugs.archlinux.org/task/75178

Disabling indirect branch tracking allows the machine to boot for me.

Re: [SOLVED] Unable to boot on installation medium with Hyper-V Gen2

Hi,

Thank you very much to all of you for your answers.
I was able to boot the installation medium properly by adding "ibt=off" to the kernel parameters (to those wondering, just press e when prompted on where to boot, and then add "ibt=off" at the end of the line starting with "linux")

Since it's an open issue and my problem is solved, I'll mark this as solved.

Thanks again,

MsFrips

This problem seems to have been fixed in the latest kernel 6.7.2-arch1-2 on win11 22H2.
