由於沒有 kqemu 的 qemu 實在太慢了

所以小弟效棄使用了(因不想花時間 compile kqemu),

以下筆記仍未完成, 敬請原諒 = , =

 

====================================

安裝:

apt-get install qemu

====================================

建立影像檔:

qemu-img create -f qcow2 vm-linux-base.img 1G

cow 是指 Copy On Write

 

====================================

插入 CD 到虛擬機:

主要指令 "-cdrom"

載入實體CD方法:
qemu -cdrom /dev/cdrom -hda vm-linux-base.img -m 256 -boot d

載入影像檔方法:
qemu -cdrom debian-40r4a-i386-netinst.iso -hda vm-linux-base.img -m 256 -boot d

====================================

QEMU Monitor

(在 putty 內係用唔到的)

Ctrl+Alt+1
主晝面

Ctrl+Alt+2
進入指令介面

指令:

commit
將以 -snapshot 的檔案寫回 img

info XXXX

eject

-----------------
stop
暫停
cont
繼續
system_reset
重開
-----------------

====================================

保存即時狀態

這裡指的狀態是指 CPU state, RAM, device state, writable disks

info snapshots
查看現有什麼影像檔

savevm TAG
保存

loadvm TAG
還原

delvm TAG
刪除

====================================

VNC

qemu ... -vnc :1 -usbdevice tablet -monitor stdio

-vnc :X (X = display number, e. g. "1").
-usbdevice tablet is used to avoid annoying mouse effects.
-monitor stdio redirects QEMU monitor to the console

vncviewer -FullColor 192.168.123.254:1

 

====================================

Overlay images

qemu-img create -b os.img -f qcow os.ovl

qemu ... -hda os.ovl ...

`commit [-f fmt] filename'
Commit the changes recorded in filename in its base image.

`info [-f fmt] filename'

====================================

Snapshot mode

temporary file created in `/tmp'

Ctrl-a s
Save disk data back to file (if -snapshot)

====================================

VM snapshots

 

info snapshots

loadvm

savevm

delvm

====================================

debian-root

qemu-make-debian-root [-k] size-in-MiB distrib deburl image [files-to-copy-in-/root]

* The generated image is not bootable by itself

qemu disk.img -kernel /boot/vmlinuz

 

====================================

 

 

====================================

usage: qemu [options] [disk_image]

 

 

-hda/-hdb/-hdc/-hdd

-cdrom file
use 'file' as IDE cdrom image (cdrom is ide1 master)

-boot [a|c|d]
boot on floppy (a), hard disk (c) or CD-ROM (d)

-m megs
set virtual RAM size to megs MB [default=128]

-localtime
set the real time clock to local time [default=utc]

 

====================================

qemu ... -vnc :1 -usbdevice devname

devname:

host:bus.addr

host:vendor_id:product_id

mouse
keyboard

 

====================================

User-mode

qemu-i386 -L / /bin/ls

-L path set the directory for the BIOS and VGA BIOS

(default=/usr/gnemul/qemu-arm).

====================================

QEMU Accelerator Module

 

(qemu) info kqemu

qemu -hda c.img -m 256 -kernel-kqemu

====================================
