Hi folks, As you probably know NetBSD can supports dom0, domU in i386, i386PAE, amd64 modes. I have found one bug which I would like to fix in our implementation, but I need some guidance to be able to identify what's wrong. If I create HVM domain with disk located on hw device or Logical Volume disk = [ 'file:/home/xenstuff/FreeBSD.img,ioemu:hda,w', 'phy:/dev/mapper/rvg00-testlv,ioemu:hdb,w' ] disk hdb(size 20Gb) is detected as this (from xm dmesg) (XEN) HVM27: ata0-0: PCHS=14563/16/63 translation=none LCHS=1024/16/63 (XEN) HVM27: ata0 master: QEMU HARDDISK ATA-7 Hard-Disk (7168 MBytes) (XEN) HVM27: ata0-1: PCHS=81/16/63 translation=none LCHS=81/16/63 (XEN) HVM27: ata0 slave: QEMU HARDDISK ATA-7 Hard-Disk ( 40 MBytes) (XEN) HVM27: (XEN) HVM27: Press F10 to select boot device.

Done register platform. I/O request not ready: 0, ptr: 0, port: 0, data: 0, count: 0, size: 0 I have changed raw_getlength to support NetBSD, so there shouldn't be problem in device size detection. I think that problem is somewhere in NetBSD but I need some guidance where to look in xen source tree to find out what can be wrong. This problem was found on xen-3.3.2 and xen-unstable. Do you have any ideas where I should look to fix this problem ?
