error trying to add second CD to virt machine

[David Kaplan]

Binary package hint: virt-manager

I am running Hardy with all the update, as well as the proposed update to virt-manager: 0.5.3-0ubuntu10. I have successfully installed and am running a Windows XP virtual machine. The virtual machine currently has a disk image as the only hard drive and an .iso of the windows XP installation CD as the only CD. I now want to use a different CD, but I am having problems. When I try to add another CD device from the "Virtual Machine Details" window, I get the following error:

 Unable to complete install: 'There are no more available virtual disk device nodes'

When I try to "disconnect" the current CD (which presumably allows me to choose a different ISO to attach?), I get the following error:

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/details.py", line 851, in toggle_cdrom
    self.vm.disconnect_cdrom_device(self.window.get_widget("disk-target-device").get_text())
  File "/usr/share/virt-manager/virtManager/domain.py", line 610, in disconnect_cdrom_device
    self._change_cdrom(result, origdisk)
  File "/usr/share/virt-manager/virtManager/domain.py", line 557, in _change_cdrom
    self.vm.attachDevice(newxml)
  File "/usr/lib/python2.5/site-packages/libvirt.py", line 214, in attachDevice
    if ret == -1: raise libvirtError ('virDomainAttachDevice() failed', dom=self)
libvirtError: virDomainAttachDevice() failed only CDROM disk devices can be attached

When I eject the existing Windows XP CD from inside the virtual machine, this works, but there is no way to "insert" a new CD.

The only solution that I have found is to shutoff the virtual machine, delete the existing IDE CD and re-add the IDE CD, but now pointing to the new .iso file. This works, but is not very practical.

I'm experiencing the same issue except that I am unable to install Windows XP at all as a result of this bug. My version of Windows XP is an upgrade which requires the user to insert an older Windows CD (e.g. Windows 2000) during the install process. I cannot figure out a way around this.

Is there any info about this error?
I am having the same problem with a Windows 2003 server guest..

I wouldn't hold your breath waiting for a response on this one....

Thanks for reporting this issue.
Do you still have it?
Are you able to reproduce it with a recent version of Ubuntu, such as Karmic or Lucid?
