Created attachment 666578 [details]
guest call trace logs.
Seems physical_block_size and logical_block_siz only can be set 512 or 4096. A little aggressive. This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux. Assigning to Stefan, he did the upstream patch. Are these in the whitelist though? Thanks Paolo and sorry for the late response. Here's the error message we get upstream: $ qemu-system-x86_64 -drive file=test.img,if=none,id=drive-data-disk,format=raw,cache=none,aio=native,werror=stop,rerror=stop -device virtio-blk-pci,bus=pci.0,addr=0x6,scsi=off,drive=drive-data-disk,id=data-disk,physical_block_size=1000,logical_block_size=1000 qemu-system-x86_64: -device virtio-blk-pci,bus=pci.0,addr=0x6,scsi=off,drive=drive-data-disk,id=data-disk,physical_block_size=1000,logical_block_size=1000: Property data-disk.physical_block_size doesn't take value '1000', it's not a power of 2 Let's backport the fix for RHEL 6.5. Reproduce this bug as follow version:
Host
# uname -r
2.6.32-393.el6.x86_64
# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.356.el6.x86_64
Guest:win2012-64
Steps:
1.Boot guest with
-drive file=/root/test1.raw,if=none,id=drive-data-disk,format=raw,cache=none,aio=native,werror=stop,rerror=stop -device virtio-scsi-pci,bus=pci.0,addr=0x6,id=scsi0 -device scsi-hd,drive=drive-data-disk,bus=scsi0.0,id=data-disk,physical_block_size=1000,logical_block_size=1000

Verify this bug as follow version:
Host
# uname -r
2.6.32-393.el6.x86_64
# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.377.el6.x86_64
steps as same as reproduce
Results:Error info
qemu-kvm: -device scsi-hd,drive=drive-data-disk,bus=scsi0.0,id=data-disk,physical_block_size=1000,logical_block_size=1000: Property 'scsi-hd.physical_block_size' doesn't take value '1000'
Addtional info:
1)I also tried virtio-blk and ide-drive.Also can give error info:
...
qemu-kvm: -device ide-drive,drive=drive-data-disk,id=data-disk,physical_block_size=3000,logical_block_size=3000: Property 'ide-drive.physical_block_size' doesn't take value '3000'
2)Also test other values ,can give error info.
...physical_block_size=2000,logical_block_size=2000...
...physical_block_size=3000,logical_block_size=3000...
According to above test ,this bug fixed.
