Prepare MSD Partition

Create MSD Partition

Before applying the patch, you would need to resize your installation partition on the SD card using GParted and create an additional partition for the msd. Finally, you need to add a mount entry for the new partition to /etc/fstab where /dev/mmcblk0p3 matches the name of the new partition you created.

/dev/mmcblk0p3 /var/lib/kvmd/msd  ext4  nodev,nosuid,noexec,ro,errors=remount-ro,data=journal,X-kvmd.otgmsd-root=/var/lib/kvmd/msd,X-kvmd.otgmsd-user=kvmd  0 0

Apply kvmd MSD Patch

  1. Download the msd patch and apply it.
cd /usr/lib/python3/dist-packages/kvmd
sudo wget -q https://github.com/RainCat1998/Bli-PiKVM/raw/main/3.291msd.patch -O 3.291msd.patch
sudo patch -p1 < 3.291msd.patch
  1. Remove the following entries from /etc/kvmd/override.yaml.
    msd:
        type: disabled
  1. Reboot & Enjoy

NOTE: This patch is only for kvmd 3.291.

The patch code is ported from fruity-pikvm by @jacobbar.
