[Qemu-devel] IO : Disk Sector Reads not aligned

[Saptarshi Sen]

Hi,

   I am trying to monitor the disk access pattern from the guest.

   and i am using an IDE as my virtual hard drive. My observation is that

   the sector reads are not 512 bytes aligned.

   I am gathering the stats from hw/ide/core.c in the function

   ide_dma_cb. variable :sector_num

   Should not these disk reads be 512 bytes aligned.

   Please help.

Regards
