Hi Dustin, Apologies for the delay (I mostly do stuff at the weekend). I've just tried current Lucid with qemu-kvm 0.12.3-0ubuntu7and kernel 2.6.32-15-generic #22-Ubuntu and the lucid-alpha3 desktop amd64 iso for the guest, and the problem is the same.
The backing disk is a raw lvm2 logical volume (/dev/mapper/main-fiddle2disk), it's in a normal volume group with a single physical volume of /dev/sda3 which is a partition on the SATA disk. The failure seems to be 100% repeatable - the block number it fails at is non-repeatable - I have tried this about 5 times now (once with this latest version, a few more times with previous versions) and have not had a successful installation. I have managed an installation using an emulate SCSI disk rather than virtio. One thing I saw today which I don't believe I had previously seen is in the host dmesg I'm seeing some audit entries: [10772.370241] type=1503 audit(1267889473.222:28): operation="capable" pid=5766 parent=1 profile="libvirt-fd06659e-3354-cb8e-71d9-cfeeff86e60f" name="sys_ptrace" [10772.370528] type=1503 audit(1267889473.222:29): operation="capable" pid=5789 parent=1 profile="libvirt-fd06659e-3354-cb8e-71d9-cfeeff86e60f" name="sys_ptrace" [10772.379636] type=1503 audit(1267889473.232:30): operation="capable" pid=5792 parent=1 profile="libvirt-fd06659e-3354-cb8e-71d9-cfeeff86e60f" name="sys_ptrace" [10788.216465] type=1503 audit(1267889489.092:31): operation="capable" pid=5767 parent=1 profile="libvirt-fd06659e-3354-cb8e-71d9-cfeeff86e60f" name="sys_rawio" [10788.247112] type=1503 audit(1267889489.122:32): operation="capable" pid=5766 parent=1 profile="libvirt-fd06659e-3354-cb8e-71d9-cfeeff86e60f" name="sys_rawio" [10791.174155] type=1503 audit(1267889492.052:33): operation="capable" pid=5766 parent=1 profile="libvirt-fd06659e-3354-cb8e-71d9-cfeeff86e60f" name="sys_rawio" [10791.429616] type=1503 audit(1267889492.312:34): operation="capable" pid=5767 parent=1 profile="libvirt-fd06659e-3354-cb8e-71d9-cfeeff86e60f" name="sys_rawio" [10820.832664] type=1503 audit(1267889521.762:35): operation="capable" pid=5766 parent=1 profile="libvirt-fd06659e-3354-cb8e-71d9-cfeeff86e60f" name="sys_rawio" but it's not clear to me that's related and you would have thought it would have failed earlier if it couldn't do any IO?? Todays failure happened about 5% through the install and the errors in the guest's dmesg were: end_request: I/O error, dev vda, sector 25702959 Buffer I/O error on device vda1, logical block 3212862 SMART on the host disk still looks good ('No Errors logged').
