Run boot-able ISO with QEMU
ISO mime types:
application/x-iso9660-image; charset=binary application/octet-stream; charset=binary
Check if ISO is bootable and run QEMU if it is.
iso-run.sh
#!/bin/bash if [ 'XX'"$1" != 'XX' ]; then if [ -f "$1" ];then IfExec=$(isoinfo -d -i "$1" | grep '(bootable)') if [ 'XX'"$IfExec" != 'XX' ]; then qemu-system-x86_64 -soundhw ac97 -k sv -vga std -machine accel=kvm,kernel_irqchip=on -cpu host -m 1G -cdrom "$1" else echo The '"' "$1" '"' is NOT boot-able. fi else echo The '"' "$1" '"' is not valid. fi else Use path to the bootable ISO file fi
In the examples are used KVM modules that need to be loaded depends on your system architecture.
#kvm #kvm-amd # For AMD CPUs #kvm-intel # For Intel CPUs
