In attempting to set up virtual machines, there’s still one obstacle that needs to be resolved: When attempting to register the CD-/DVD-ROM of my computer with libvirtd (so I can insert the appropriate installation media for the guest OSes) vm-manager starts complaining and issues the following error message:
Could not start storage pool: Internal error: Subprocess (/usr/lib64/libvirt/libvirt_parthelper /dev/sr0) unexpected termination status 2
(this might not be entirely accurate since I need to translate back from the German version)
Any ideas on how to convince libvirtd to accept the device?
If possible, I would like to circumvent generating an ISO image and put it into /var/lib/libvirt/images or any similar method.
Just circumvented this problem by adding pre-formatted fs storage…
This mounts the optical volume in /var/lib/libvirt/images/<subdir> and should circumvent this problem.
However, I have run into another problem: When attempting to allocate a physical partition as guest OD storage (I managed to add both the entire hd and the partition(s) in question as potential storage) libvirt complains again: Error creating domain: Block device type “qemu” is invalid. - however, according to the error dialog this seems to point to xend instead of libvirtd…
Unfortunately I haven’t found a means to resolve this issue so creating that particular domU fails.
Try storing your ISO files in a different location… AFAIK the location you’ve chosen is typically used for storing the VM disk images, not ISO images. I haven’t tried to store ISO images there just because it doesn’t make sense to me, and I would expect the location you’ve chosen likely has special file permissions as well as the issue you’re describing.
To me, it’s logical to place resources which should be available system-wide in a location that’s not specific to any technology, application, or use.
I typically create a location immediately off the root, eg /ISO/
I’d assume a network share can be suitable as well although of course that could involve severe performance penalties.
