QEmu emulates a computer, so you can use it to run several operating system images on one physical computer. Regarding the user experience, emulation is the same as virtualization, just slower.
Contents
Install it
SUSE
yast -i qemu
Use it
Create a virtual harddisk
With 2GB:
qemu-img create -f raw harddisk.img 2G
start with networking
modprobe tun qemu -k de-ch -m 256 -hda harddisk.img -cdrom cdromimage -boot d -net tap
exchange CD
- change to qemu konsole by pressing CTRL_2
- enter the command
eject cdrom
- insert next CD and enter
change cdrom /dev/cdrom
- Zugriff auf die virtuelle Platte
access the virtual harddisk
Use mtools to access the virtual hard disk. Enter into ~/.mtoolsrc:
mtools_skip_check=1 drive c: file="/home/user/qemu/harddisk.img" partition=1
Now you can show the virtual disk's content using the command
mdir c:
And copy files like
mcopy file c:
