Subject: [Qemu-devel] [Bug 1600563] [NEW] min_io_size is currently limited to size uint16_t
Date: Sun, 10 Jul 2016 07:51:25 -0000 [thread overview]
Message-ID: <20160710075125.17855.72473.malonedeb@wampee.canonical.com> (raw)
Public bug reported:
I am using LVM VGs on MD-raid1 for hosting my KVM volumes. On the host,
a VG looks like this:
Disk /dev/vm/vol202a: 60 GiB, 64424509440 bytes, 125829120 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 131072 bytes / 131072 bytes
In order to replicate the block device characteristics in the guest, I
am using the following extra parameters:
-set device.scsi0-0-0-0.logical_block_size=512
-set device.scsi0-0-0-0.physical_block_size=4096
-set device.scsi0-0-0-0.min_io_size=131072
This doesn't work as qemu complains that min_io_size needs to be of type
uint16_t.
