Description

The original description of the problem is from Florian in the mailing list:

Hi,

Is it normal that when you create a virtual machine and you configure one of its disk as a cdrom :

#########Open nebula VM Template #########
...
OS = [ BOOT = \"cdrom\" ]
...
DISK = [ TYPE = "cdrom" ,
SOURCE = "/srv/cloud/one/IM_template/debian-504-i386-netinst.iso" ,
TARGET = "hdc" ,
CLONE = "no" ,
SAVE = "no" ,
READONLY = "no" ]
DISK = [ TYPE = "disk" ,
SOURCE = "/srv/cloud/one/IM_template/test.qcow2" ,
TARGET = "hda" ,
CLONE = "no" ,
SAVE = "no" ,
READONLY = "no" ]
...
################################

the libvirt driver translate it like this :

#########LibVirt VM Template #########
...
<os>
                <type>hvm</type>
                <boot dev='"cdrom"'/>
        </os>
        <devices>
                <emulator>/usr/bin/kvm</emulator>
                <disk type='file' device='disk'>
                        <source file='/srv/cloud/one/var/94/images/disk.0'/>
                        <target dev='hdc'/>
                </disk>
                <disk type='file' device='disk'>
                        <source file='/srv/cloud/one/var/94/images/disk.1'/>
                        <target dev='hda'/>
                </disk>
...

That is to say the translation doesn't care about my cdrom type . And the vm failed. but if I put cdrom in the device attirbute it works ...

I searched in the code and I realized that if the type is block in the ON template the device attirbute will be set as disk and if not it will be set at disk again : root / src / vmm / LibVirtDriver.cc line 687 to 697 ...
