Public bug reported:

I have configured 2 ide disks with name starting with hd, but when the
vm boots up, it shows disks whose name starting with sd.

1. ide disks in vm xml:

    <disk type='file' device='disk'>
      <driver name='qemu' type='raw'/>
      <source file='/data3_raw.qcow2'/>
      <target dev='hdc' bus='ide'/>
    </disk>
    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2'/>
      <source file='/data2.qcow2'/>
      <target dev='hdb' bus='ide'/>
    </disk>


2. in VM:

sda            8:0    0    2G  0 disk
sdb            8:16   0    1G  0 disk


3. from vm.log:

le=/data2.qcow2,format=qcow2,if=none,id=drive-ide0-0-1 -device ide-
hd,bus=ide.0,unit=1,drive=drive-ide0-0-1,id=ide0-0-1 -drive
file=/data3_raw.qcow2,format=raw,if=none,id=drive-ide0-1-0 -device ide-
hd,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev t


4. rpm info: (I got the same issue on 2 diff envs)
(1) env1
qemu-kvm-1.5.3-105
libvirt-3.2.0-14.el7
(2) env2
libvirt-5.9.0-1.el8

This looks more like a libvirt question than a qemu one.

The name that libvirt chooses to identify disks from the host 
perspective is independent...

...from what the guest OS chooses to use.  Although there are many 
situations where a Linux guest will pick the same names as libvirt chose 
on the host side based on the transport (such as SCSI or virtio), there 
is no guarantee that this is always the case, nor that your guest is 
always running Linux as its OS.

Thanks a lot for the reply.


But from the cmdline of qemu, we can see as following, libvirt passed "-device" option with "ide-hd, bus=ide.0" to qemu. I am wondering why qemu received this option, but it is still dealing it as scsi bus device instead of ide bus device, since with "lssci" cmd, we can see the ide disk we configured in xml.

Which kernel / linux distro are you using in the guest? Can you spot
something related in the output of "dmesg" in the guest?
