Hi, thanks for the report; do you have a QEMU command line that we can use to help reproduce the problem? It's easiest if we can cut libvirt out of the loop. What is the architecture and version of the guest? Lastly, it looks like this worked in our 2.7 release if I'm reading you correctly, so this is a change for the 2.8 release as far as you can tell, right? --js > ===================================================================== > > XML-Declration: > > . > . > . > > <!-- SCSI 2 --> > <controller type='scsi' model='virtio-scsi' index='1'> > <alias name='scsi1'/> > </controller> > > <!-- 2 x LTO5 --> > <hostdev mode='subsystem' type='scsi' managed='no' rawio='yes'> > <source protocol='iscsi' > name='iqn.2008-09.net.fsc:server.LT260_61003/4'> > <host name='etcsvms2.abg.fsc.net' port='3260'/> > </source> > <address type='drive' controller='1' bus='0' target='2' unit='1'/> > </hostdev> > > <hostdev mode='subsystem' type='scsi' managed='no' rawio='yes'> > <source protocol='iscsi' > name='iqn.2008-09.net.fsc:server.LT260_61003/5'> > <host name='etcsvms2.abg.fsc.net' port='3260'/> > </source> > <address type='drive' controller='1' bus='0' target='2' unit='2'/> > </hostdev> > > <!-- Virtual media changer Fujitsu LT260 --> > <hostdev mode='subsystem' type='scsi' managed='no' rawio='yes'> > <source protocol='iscsi' > name='iqn.2008-09.net.fsc:server.LT260_61003/6'> > <host name='etcsvms2.abg.fsc.net' port='3260'/> > </source> > <address type='drive' controller='1' bus='0' target='2' unit='3'/> > </hostdev> > > <!-- 2 x LTO6 (via PLP(LAN-attached library)) --> > <hostdev mode='subsystem' type='scsi' managed='no' rawio='yes'> > <source protocol='iscsi' > name='iqn.2008-09.net.fsc:server.LT60_61005/3'> > <host name='etcsvms2.abg.fsc.net' port='3260'/> > </source> > <address type='drive' controller='1' bus='0' target='2' unit='4'/> > </hostdev> > > <hostdev mode='subsystem' type='scsi' managed='no' rawio='yes'> > <source protocol='iscsi' > name='iqn.2008-09.net.fsc:server.LT60_61005/4'> > <host name='etcsvms2.abg.fsc.net' port='3260'/> > </source> > <address type='drive' controller='1' bus='0' target='2' unit='5'/> > </hostdev> > . > . > . > > =============================================================================== > > > correct behavior/Result inside the VM-Quest together with QEMU/KVM 2.6.2 > / 2.7.0 > -- > (VCSTCS82:A)IUP1:~ # lsscsi -g > [0:2:0:0] disk FTS PRAID EP420i 4.25 /dev/sda /dev/sg0 > [3:0:0:0] cd/dvd QEMU QEMU DVD-ROM 2.5+ /dev/sr0 /dev/sg1 > [8:0:2:1] tape HP Ultrium 5-SCSI 0001 /dev/st3 /dev/sg6 > [8:0:2:2] tape HP Ultrium 5-SCSI 0001 /dev/st2 /dev/sg5 > [8:0:2:3] mediumx FUJITSU ETERNUS LT260 6.20 - /dev/sg4 > [8:0:2:4] tape HP Ultrium 6-SCSI 23AB /dev/st1 /dev/sg3 > [8:0:2:5] tape HP Ultrium 6-SCSI 23AB /dev/st0 /dev/sg2 > [11:0:0:0] disk FUJITSU ETERNUS_DXL 0000 /dev/sdb /dev/sg7 > [11:0:0:2] disk FUJITSU ETERNUS_DXL 0000 /dev/sdh /dev/sg13 > [11:0:0:3] disk FUJITSU ETERNUS_DXL 0000 /dev/sdg /dev/sg12 > [11:0:0:4] disk FUJITSU ETERNUS_DXL 0000 /dev/sdf /dev/sg11 > [11:0:0:5] disk FUJITSU ETERNUS_DXL 0000 /dev/sde /dev/sg10 > [11:0:0:6] disk FUJITSU ETERNUS_DXL 0000 /dev/sdd /dev/sg9 > [11:0:0:7] disk FUJITSU ETERNUS_DXL 0000 /dev/sdc /dev/sg8 > [11:0:0:15] disk FUJITSU ETERNUS_DXL 0000 /dev/sdi /dev/sg14 > (VCSTCS82:A)IUP1:~ # > > > > Wrong behavior/Result inside the VM-Quest together with QEMU/KVM 2.8.0-RC4 > -- > (VCSTCS82:A)IUP1:~ # lsscsi -g > [0:2:0:0] disk FTS PRAID EP420i 4.25 /dev/sda /dev/sg0 > [3:0:0:0] cd/dvd QEMU QEMU DVD-ROM 2.5+ /dev/sr0 /dev/sg1 > [11:0:1:0] disk FUJITSU ETERNUS_DXL 0000 /dev/sdj /dev/sg10 > [11:0:1:2] disk FUJITSU ETERNUS_DXL 0000 /dev/sdp /dev/sg16 > [11:0:1:3] disk FUJITSU ETERNUS_DXL 0000 /dev/sdo /dev/sg15 > [11:0:1:4] disk FUJITSU ETERNUS_DXL 0000 /dev/sdn /dev/sg14 > [11:0:1:5] disk FUJITSU ETERNUS_DXL 0000 /dev/sdm /dev/sg13 > [11:0:1:6] disk FUJITSU ETERNUS_DXL 0000 /dev/sdl /dev/sg12 > [11:0:1:7] disk FUJITSU ETERNUS_DXL 0000 /dev/sdk /dev/sg11 > [11:0:1:15] disk FUJITSU ETERNUS_DXL 0000 /dev/sdq /dev/sg17 > (VCSTCS82:A)IUP1:~ # >
