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?
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? <domain type="kvm"> <name>serv-bd-dev1</name> <uuid>0e3ffc7c-4e54-405c-9af1-55bc4f25fe13</uuid> <memory>4194304</memory> <currentMemory>4194304</currentMemory> <vcpu>4</vcpu> <memtune> <min_guarantee>349184</min_guarantee> </memtune> <devices> <channel type="unix"> <target name="com.redhat.rhevm.vdsm" type="virtio"/> <source mode="bind" path="/var/lib/libvirt/qemu/channels/0e3ffc7c-4e54-405c-9af1-55bc4f25fe13.com.redhat.rhevm.vdsm"/> </channel> <channel type="unix"> <target name="org.qemu.guest_agent.0" type="virtio"/> <source mode="bind" path="/var/lib/libvirt/qemu/channels/0e3ffc7c-4e54-405c-9af1-55bc4f25fe13.org.qemu.guest_agent.0"/> </channel> <input bus="usb" type="tablet"/> <graphics autoport="yes" keymap="fr" passwd="*****" passwdValidTo="1970-01-01T00:00:01" port="-1" type="vnc"> <listen network="vdsm-ovirtmgmt" type="network"/> </graphics> <controller model="virtio-scsi" type="scsi"/> <video> <address bus="0x00" domain="0x0000" function="0x0" slot="0x02" type="pci"/> <model heads="1" type="qxl" vram="65536"/> </video> <interface type="bridge"> <address bus="0x00" domain="0x0000" function="0x0" slot="0x03" type="pci"/> <mac address="00:1a:4a:a8:27:0c"/> <model type="e1000"/> <source bridge="ovirtmgmt"/> <filterref filter="vdsm-no-mac-spoofing"/> <link state="up"/> </interface> <disk device="cdrom" snapshot="no" type="file"> <address bus="1" controller="0" target="0" type="drive" unit="0"/> <source file="" startupPolicy="optional"/> <target bus="ide" dev="hdc"/> <readonly/> <serial/> </disk> <disk device="disk" snapshot="no" type="block"> <address bus="0" controller="0" target="0" type="drive" unit="0"/> <source dev="/rhev/data-center/5849b030-626e-47cb-ad90-3ce782d831b3/1429ffe2-4137-416c-bb38-63fd73f4bcc1/images/c38a73f0-da9e-4e52-ad63-78e64fce957c/7a74ba80-9207-4f21-90a0-f28fc9925fee"/> <target bus="ide" dev="hda"/> <serial>c38a73f0-da9e-4e52-ad63-78e64fce957c</serial> <boot order="1"/> <driver cache="none" error_policy="stop" io="native" name="qemu" type="qcow2"/> </disk> <disk device="disk" snapshot="no" type="block"> <address bus="1" controller="0" target="0" type="drive" unit="1"/> <source dev="/rhev/data-center/5849b030-626e-47cb-ad90-3ce782d831b3/11a077c7-658b-49bb-8596-a785109c24c9/images/36553e2f-64f2-4d4e-b8a1-d9cd7d1cdf49/e610a133-1f96-4c6a-8be5-efd1fdc413b6"/> <target bus="ide" dev="hdb"/> <serial>36553e2f-64f2-4d4e-b8a1-d9cd7d1cdf49</serial> <driver cache="none" error_policy="stop" io="native" name="qemu" type="qcow2"/> </disk> <disk device="disk" snapshot="no" type="block"> <address bus="0" controller="0" target="0" type="drive" unit="1"/> <source dev="/rhev/data-center/5849b030-626e-47cb-ad90-3ce782d831b3/1429ffe2-4137-416c-bb38-63fd73f4bcc1/images/f9ca88d8-e29f-4b11-9aae-b9330b5f8cdf/ed91505a-a219-42af-9915-e5ffc79918f9"/> <target bus="ide" dev="hdd"/> <serial>f9ca88d8-e29f-4b11-9aae-b9330b5f8cdf</serial> <driver cache="none" error_policy="stop" io="native" name="qemu" type="qcow2"/> </disk> <memballoon model="virtio"/> </devices> <os> <type arch="x86_64" machine="rhel6.4.0">hvm</type> <smbios mode="sysinfo"/> </os> <sysinfo type="smbios"> <system> <entry name="manufacturer">oVirt</entry> <entry name="product">oVirt Node</entry> <entry name="version">6-4.el6.centos.10</entry> <entry name="serial">4C4C4544-0036-3310-805A-B1C04F585831</entry> <entry name="uuid">0e3ffc7c-4e54-405c-9af1-55bc4f25fe13</entry> </system> </sysinfo> <clock adjustment="-2" offset="variable"> <timer name="rtc" tickpolicy="catchup"/> </clock> <features> <acpi/> </features> <cpu match="exact"> <model>SandyBridge</model> <topology cores="4" sockets="1" threads="1"/> </cpu> </domain> -- Nicolas Ecarnot
