Hi,
Strarting from a VM with two IDE disks, I'm trying to add a third IDE disk.
I get this Duplicate ID error :
VM serv-bd-dev1 is down. Exit message: internal error process exited
while connecting to monitor: qemu-kvm: -drive
file=/rhev/data-center/5849b030-626e-47cb-ad90-3ce782d831b3/1429ffe2-4137-416c-bb38-63fd73f4bcc1/images/f9ca88d8-e29f-4b11-9aae-b9330b5f8cdf/ed91505a-a219-42af-9915-e5ffc79918f9,if=none,id=drive-ide0-1-1,format=qcow2,serial=f9ca88d8-e29f-4b11-9aae-b9330b5f8cdf,cache=none,werror=stop,rerror=stop,aio=native:
Duplicate ID 'drive-ide0-1-1' for drive .
When disabling the second one and starting only with disk 0 et the new
one (so start with 2 disks), it is booting well.
Is it by design?
(oVirt 3.3, no shared disk, thin-provisioned)

No. It sounds like a collision between the address of your third ide
disk and the ide cdrom. Would you post vdsm.log from vmCreate command
until the reported error message? It would let us understand if the bug
is in Vdsm or Engine.

No. It sounds like a collision between the address of your third ide
disk and the ide cdrom. Would you post vdsm.log from vmCreate command
until the reported error message? It would let us understand if the bug
is in Vdsm or Engine.
Dan.
Do you mean the xml that one can see in the vdsm.log?

Actually, I've meant everything: from Engine's parameters to the
vmCreate command, down to the error from libvirt. The domxml blow
suggests that the error might be even further below, since I do not see
an address collision here.
<disk device="cdrom" snapshot="no"
type="file">
<address bus="1" controller="0" target="0"
type="drive" unit="0"/>
<target bus="ide" dev="hdc"/>
</disk>
<disk device="disk" snapshot="no" type="block">
<address bus="0" controller="0" target="0"
type="drive" unit="0"/>
<target bus="ide" dev="hda"/>
</disk>
<disk device="disk" snapshot="no" type="block">
<address bus="1" controller="0" target="0"
type="drive" unit="1"/>
<target bus="ide" dev="hdb"/>
</disk>
<disk device="disk" snapshot="no" type="block">
<address bus="0" controller="0" target="0"
type="drive" unit="1"/>
<target bus="ide" dev="hdd"/>
</disk>
Could you provide the vmCreate line from vdsm.log, and also the part of
libvirtd.log since that domxml gets in until the error is spewed out?

Wow, this is weird!
After some shutdown/reboot (I have other things to do with this VM), I
CAN NOT reproduce the issue.
I swear I have not changed the disk setup, neither added a component or
what else.
What I get now is the VM up and running with 3 IDE disks, a state I
couldn't reach so far. I don't know what to conclude?

shutdown/reboot of what? Vm? Host? Engine?
Maybe you have still access to the old vdsm.logs? Otherwise the
conclusion is that someone else would bump into this bug..
I have a suspicion that Engine is somehow confused by the device
addresses reported by Vdsm. But I'd need to see the logs to stop
guessing.
