NetBSD 絹の日記

  CPU core i7 7700  (not for Windows 11)
  Box: ThinkCenter m710s
  Memory 32 GB

Install 10.99.10 (NetBSD/amd64)
set some parameters on BIOS screen
1. Intel(R) Hyper-Threading Technology
2. Intel(R) Virtualization Technology
Probably the latter is necessary
sudo modload nvmm
pkgin install qemu (qemu-8.2.2nb2)

prepare image file

   qemu-img create -f qcow2 /G/rootfs.qcow2 120G
   qemu-img create -f qcow2 /H/rootfs.qcow2 120G

run xterm

(inside xterm)

  sudo -s
  export XAUTHORITY=/home/makoto/.Xauthority

install 9.4 on Guest 9.4

run 9.4 for Guest

I tried Guest as

  10.99.10 (202405031500Z)  -> panic
   9.4                      -> OK
  10.0                      -> OK

The reason of this panic is missing /dev/console probably because of i915drmkms issue.

userconf disable i915drmkms

at booting may be the answer, Michael van Elst helped at irc at #NetBSD

＠ setup bridge for inside/outside guest:

(https://www.netbsd.org/docs/guide/en/chap-virt.html#chap-virt-net-bridge)

/etc/ifconfig.tap0

 create
 descr "NetBSD VM" up
 ! ifconfig bridge0 create
 ! ifconfig bridge0 descr "LAN VM bridge" up
 ! brconfig bridge0 add tap0 add re0

at reboot, I needed

userconf disable i915drmkms

and, once rebooted in /boot.cfg

thinkc03# qemu-system-x86_64 \
  -smp 8 \
  -m 16G  \
  -accel nvmm \
  -drive driver=qcow2,file=/G/rootfs.qcow2,if=virtio \

  -rtc base=localtime,clock=host \

  -drive file=/home/makoto/Downloads/NetBSD-10.99.10-amd64.iso,index=1,media=cdrom -boot c \
  -netdev tap,id=tap0,ifname=tap0,script=no -device virtio-net-pci,netdev=tap0

(not communicating to inside yet)

＠ now bridge if works with this setup:

  -netdev tap,id=tap0,ifname=tap0,script=no -device virtio-net-pci

This enables bridge interface,
