[Bug 827590] Re: cloud-init does not mount ephemeral0 on /mnt in nova
I understand that actually mapping a device name from hypervisor to
guest is actually impossible, but hopefully we can come up with a better
guess.
Its unfortunate that libvirt doesn't even seem to be using the dev= as
a suggestion of device ordering along the virtio bus. Instead, I'm
guessing it is using order present in xml. I was hoping at very least
that suggesting 'vda', 'vdb', 'vdc' would render in kvm command line to
addr=0x4, addr=0x5, addr=0x6 respectively.
Since libvirt seems to be relying on order in the xml, is it possible to
specify the correct order and also sane dev= attributes?
Ie, what would happen if you had xml like:
| disk type='file'
| driver type='qcow2'/
| source file='/var/lib/nova/instances/instance-00e4/disk'/
| target dev='vda' bus='virtio'/
| /disk
| disk type='block'
| driver type='qcow2'/
| source dev='/var/lib/nova/instances/instance-00e4/disk.eph0 '/
| target dev='vdb' bus='virtio'/
| /disk
| disk type='block'
| driver type='raw'/
| source dev='/dev/mapper/nova--volumes-volume--0040'/
| target dev='vdc' bus='virtio'/
| /disk
And then specified block device mapping like:
{
'ami': 'vda',
'root': '/dev/vda',
'ephemeral0': '/dev/vdb'
'vol0': '/dev/vdc'
}
Again, I understand, you can't force the guest to name devices in any
way, but hopefully we can at least map vda to first device on virtio
bus, and vdb to second disk on virtio bus.

Yes, you're right. The create kvm command line that libvirt created and the created xml for the guest is as follows. You can see that those target device is specified correctly in the xml, but the mapping information is lost in the command line. libvirt doesn't have any way to force the guest to use the setting in qemu-kvm case because qemu-kvm creates pci devices for each virtio-disk and the guests understands it sequentially from 'a'. In order to fix it, we need to pass those mapping information to guest from nova somehow and teach OS initialization sequence (cloud-init?/udev?) the mapping.
