[Qemu-devel] Adding New Disk Drive

[Volkan YAZICI]

Hi,

We have been using qemu for one of our Windows Server 2003 systems
successfully since previous month. Below is the script I use to start
qemu:

  $ cat /usr/local/sbin/start-windows
  #!/bin/sh
  
  # Install KVM kernel modules.
  modprobe kvm
  modprobe kvm-intel
  
  # Start qemu.
  SDL_VIDEO_X11_DGAMOUSE=0 \
  /usr/local/bin/qemu-system-x86_64 \
          -cdrom /dev/cdrom \
          -hda /home/windows/disk-qcow2-20g.img \
          -hdb /home/windows/disk-qcow2-40g.img \
          -localtime -m 1536 -smp 2 -k tr \
          -usb -usbdevice tablet \
          -net nic -net tap

Last week we started to suffer from low disk space and to solve this
problem we purchased a Philips SPE3000 External SATA disk with USB
connectivity. And connected it to the related machine with below
configuration:

  $ ls -l /home/windows/
  total 60068704
  lrwxrwxrwx 1 windows windows          28 2008-07-30 16:18 disk-qcow2-200g.img 
-> /bak/img/disk-qcow2-200g.img
  -rw-r--r-- 1 windows windows 20957474816 2008-07-30 16:44 disk-qcow2-20g.img
  -rw-r--r-- 1 windows windows 40492793856 2008-07-30 16:44 disk-qcow2-40g.img

  # mount | grep /bak
  /dev/sdb1 on /bak type ext3 (rw,nosuid,nodev,noatime)

And I appended a "-hdc /home/windows/disk-qcow2-200g.img" line to
/usr/local/sbin/start-windows script and restarted qemu. But I saw that
drive doesn't appear in the windows side. (I can see it neither in "My
Computer", nor in "My Computer > Manage > Disk Management" window.) I
also tried using "-drive file=/home/windows/disk-qcow2-200g.img,if=scsi"
but nothing changed.

Any ideas what I might be missing? Any kind of help will be really
appreciated.


Regards.
