# Qemu
|
||
|
|
Optimized options that seem to work on MacOS:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
-m 4G -smp 6 # Resources: Use 4GB memory and 6 cpus
|
||
|
|
-machine type=q35,accel=hvf # Machine: Default is `pc`. `q35` should be better. Haven't noticed any perfomance gains
|
||
|
|
# Hypervisor: Uses HyperVisorFramework to speed up qemu a LOT, ~6x
|
||
|
|
-drive file=archlinux.qcow2,media=disk,if=virtio # Boot: Points to the image
|
||
|
|
-nic user,hostfwd=tcp::10022-:22 # Network: Forward host port 10022 to guest 22, so `ssh -p10022 user@localhost` should work
|
||
|
|
|
||
|
|
# Display options on MacOS:
|
||
|
|
# If you launch this script in the background, the same terminal can be
|
||
|
|
# used to ssh into qemu. After exiting, tmux's scrollback breaks. Opening
|
||
|
|
# and closing [n]vim fixes this...
|
||
|
|
-nographic
|
||
|
|
# Doesn't do anything noticably different from just -nographic
|
||
|
|
-monitor none -curses -nographic
|
||
|
|
# Support a 4k instance on MacOS. A spice server would be better. It's
|
||
|
|
# really laggy with KDE, to the point of unusable
|
||
|
|
-vga virtio -full-screen -display cocoa
|
||
|
|
# Only supports 1080p. MacOS must use a cocoa display. Compared to above
|
||
|
|
# the display scales by 2x which makes text bigger tho more blurry
|
||
|
|
-vga std -display cocoa
|
||
|
|
```
|
||
|
|
|

# Qemu fully nongraphic

MacOS can't use `-display ncurses` properly with qemu. Ncurses requires a linux
|
||
|
|
kernel to work properly. Instead use `-nographic` and launch the process in the
|
||
|
|
background. Bash uses `&` for backgrounding. You can now SSH into the qemu
|
||
|
|
instance.
|
||
|
|
|
||
|
|
Bonus:
|
||
|
|
For shared file systems, there are two options on Macs:
|
||
|
|
- MacFUSE - Manually setup and mount with sshfs. It's much easier to use
|
||
|
|
- lima - Tries to do reverse sshfs for you and forwards ports too. This one is
|
||
|
|
pretty new and questionably useful compared to manually using sshfs
