[Bug 1271479] [NEW] ide disk type is not set when starting vm from dashboard
Public bug reported:
Hello
we have a openstack havana controller installation with 2 compute nodes
centos 6.4 /KVM
i get 3 ide disk images from i need to build a vm by booting on the
first one and attach the 2 others as volumes
when i play the nova command line below the vm start well and volumes
are attached
nova boot --flavor vcdn_mn --key_name KEY_NAME --availability-zone nova:vcdn_kvm5 --image c5813703-2bfb-4f58-b0f1-9cd08fb8e596 --nic net-id=a2b8e7e4-cceb-4e5a-881b-8d872f6384db --nic net-id=d2292ebe-a431-4bd9-a5e4-570e2f98f169 --nic net-id=7368ec5a-3f9d-49af-a254-87a754f9b952 --block-device source=volume,dest=volume,id=8d8a2e6d-9c7e-4905-b194-8a74b6ae6c42,bus=ide,shutdown=preserve --block-device source=volume,dest=volume,id=7379756e-e435-40ad-8f0c-de43b0adcac4,bus=ide,shutdown=preserve mn1.vxn1s1.cdn
the libvirt.xml disk device section looks like :
<disk type="file" device="disk">
<driver name="qemu" type="qcow2" cache="none"/>
<source file="/var/lib/nova/instances/a8a255cd-0b60-436d-ae71-e00f28e725bd/disk"/>

<target bus="ide" dev="hdc"/>
<serial>7379756e-e435-40ad-8f0c-de43b0adcac4</serial>
</disk>
but if i restart the vm from the dashboard the libvirt.xml is modified
and looks like, the target bus is changed from "ide" to virtio" so the
vm cant boot anymore because of partition table ... :
<disk type="file" device="disk">
<driver name="qemu" type="qcow2" cache="none"/>
<source file="/var/lib/nova/instances/a8a255cd-0b60-436d-ae71-e00f28e725bd/disk"/>
<target bus="virtio" dev="hda"/>
</disk>
<disk type="block" device="disk">

<target bus="ide" dev="hdc"/>
<serial>7379756e-e435-40ad-8f0c-de43b0adcac4</serial>
</disk>
i ve tried to set libvirt_disk_prefix=hd (even if it not seems possible value..) into /etc/nova/nova.conf
i ve set some metadata on boot disk image => disk_bus, disk_dev,
hw_disk_bus without success
