[one-users] CDROM doesn't mount for KVM virts?

[Tino Vazquez]

Dear Rich,

You can try changing line 390 of src/vmm/LibVirtDriverKVM.cc

               file << "\t\t<disk type='file' device='cdrom'>" << endl;

you will need to compile, install and run OpenNebula again.

If this works, please come back and we will evaluate the possibility
of having type of cdrom as a variable in the VM template.

Regards,

-Tino
