Could you please file a Vdsm bug? Bests, ________________________________ From: "Pavel Gashev" <p...@acronis.com<mailto:p...@acronis.com>> To: users@ovirt.org<mailto:users@ovirt.org> Sent: Wednesday, March 30, 2016 4:39:14 PM Subject: [ovirt-users] payload device serial Hello, I hit a bug, and just want to share a solution. VM with a payload (Initial run) do not start with libvirt >= 1.3.2. VDSM log says: "libvirtError: unsupported configuration: Disks 'hdc' and 'hdd' have identical serial". Yes, both cdrom devices have the same serial. Empty serial: <disk device="cdrom" snapshot="no" type="file"> <source file="/var/run/vdsm/payload/2eaf9c8e-2123-4b48-9b62-f96168ac7a36.41f22cb1676858ad4e22e8440519032d.img" startupPolicy="optional"/> <target bus="ide" dev="hdd"/> <readonly/> <serial/> </disk> <disk device="cdrom" snapshot="no" type="file"> <source file="" startupPolicy="optional"/> <target bus="ide" dev="hdc"/> <readonly/> <serial/> </disk> I don't know where is the issue. Either libvirt should work with empty serials, or VDSM should generate serial at least for payload device. Related bug - https://bugzilla.redhat.com/show_bug.cgi?id=1245013 Quick fix is to install a VDSM hook to /usr/libexec/vdsm/hooks/before_vm_start: ---------- cut here ---------- #!/usr/bin/python import hooking import uuid domxml = hooking.read_domxml() for disk in domxml.getElementsByTagName('disk'): if disk.getAttribute('device') == 'cdrom': for source in disk.getElementsByTagName('source'): if source.getAttribute('file').find('/payload/') > 0: for serial in disk.getElementsByTagName('serial'): if not serial.hasChildNodes(): serial.appendChild(domxml.createTextNode(str(uuid.uuid4()))) hooking.write_domxml(domxml) ---------- cut here ---------- _______________________________________________ Users mailing list Users@ovirt.org<mailto:Users@ovirt.org> http://lists.ovirt.org/mailman/listinfo/users -- Francesco Romani RedHat Engineering Virtualization R & D Phone: 8261328 IRC: fromani
