Description of problem: Version-Release number of selected component (if applicable): Host: 3.10.0-422.el7.ppc64le qemu-kvm-rhev-2.6.0-5.el7.ppc64le Guest: 3.10.0-422.el7.ppc64le How reproducible: 100% Steps to Reproduce: 1. Create a data image. qemu-img create -f qcow2 /usr/share/avocado/data/avocado-vt/images/stg.qcow2 10G 2. Boot guest: /usr/libexec/qemu-kvm \ -S \ -name 'avocado-vt-vm1' \ -sandbox off \ -machine pseries \ -nodefaults \ -vga std \ -chardev socket,id=qmp_id_qmpmonitor1,path=/var/tmp/avocado_C5WmRT/monitor-qmpmonitor1-20160612-224056-umwCjQbc,server,nowait \ -mon chardev=qmp_id_qmpmonitor1,mode=control \ -chardev socket,id=qmp_id_catch_monitor,path=/var/tmp/avocado_C5WmRT/monitor-catch_monitor-20160612-224056-umwCjQbc,server,nowait \ -mon chardev=qmp_id_catch_monitor,mode=control \ -chardev socket,id=serial_id_serial0,path=/var/tmp/avocado_C5WmRT/serial-serial0-20160612-224056-umwCjQbc,server,nowait \ -device spapr-vty,reg=0x30000000,chardev=serial_id_serial0 \ -device pci-ohci,id=usb1,bus=pci.0,addr=03 \ -device spapr-vscsi,id=spapr_vscsi0 \ -drive id=drive_image1,if=none,cache=none,snapshot=on,aio=threads,format=qcow2,file=/usr/share/avocado/data/avocado-vt/images/RHEL-Server-7.3-ppc64le.qcow2 \ -device scsi-hd,id=image1,bus=spapr_vscsi0.0,drive=drive_image1 \ -drive id=drive_stg,if=none,cache=none,snapshot=off,aio=native,format=qcow2,file=/usr/share/avocado/data/avocado-vt/images/stg.qcow2 \ -device scsi-hd,id=stg,bus=spapr_vscsi0.0,drive=drive_stg,serial=TARGET_DISK0 \ -device spapr-vlan,mac=9a:18:19:1a:1b:1c,id=idYicXEO,netdev=idgVafY3 \ -netdev tap,id=idgVafY3 \ -m 8192 \ -smp 8,maxcpus=8,cores=4,threads=1,sockets=2 \ -device usb-tablet,id=usb-tablet1,bus=usb1.0,port=1 \ -vnc :0 \ -rtc base=utc,clock=host \ -boot order=cdn,once=c,menu=off,strict=off \ -enable-kvm \ -monitor stdio \ 3. Resize the data image. {"QMP": {"version": {"qemu": {"micro": 0, "minor": 6, "major": 2}, "package": " (qemu-kvm-rhev-2.6.0-5.el7)"}, "capabilities": []}} {"execute":"qmp_capabilities"} {"return": {}} {'execute': 'block_resize', 'arguments': {'device': 'drive_stg', 'size': 16106127360}, 'id': 'VBzqQMZY'} {"return": {}, "id": "VBzqQMZY"} 4. Check the size of 'drive_stg' in guest. # fdisk -l Disk /dev/sdb: 10.7 GB, 10737418240 bytes, 20971520 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Actual results: The size of 'drive_stg' in guest not update. Reboot guest, the size will updated. Disk /dev/sdb: 16.1 GB, 16106127360 bytes, 31457280 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Since spapr-vscsi is different from virtio, so not sure if this is a bug. If this is expected, please help close this bug, we will update the test script, thanks! Expected results: Additional info:
