[virt-tools-list] virt-make-fs: Partition 1 has different physical/logical beginnings and endings

[Sebastien Douche]

On Ubuntu 12.04, I'm trying to create a second disk for a VM. The disk
seems work well (and mounted) but I don't like the cfdisk / fdisk
message.


# virt-make-fs --partition --size=+300M --type=ext3 --format=qcow2
srv-2912.tar.gz datadisk-test.qcow2
Formatting 'datadisk-test.qcow2', fmt=qcow2 size=393837568
encryption=off cluster_size=65536

# virt-filesystems -a datadisk-test.qcow2
/dev/sda1

I add the disk on the VM:

    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2' cache='none'/>
      <source file='/srv/kvm/lib/datadisk-test.qcow2'/>
      <target dev='hdb' bus='ide'/>
      <address type='drive' controller='0' bus='1' unit='0'/>
    </disk>


The dmesg seems good :

But fdisk said :

Command (m for help): p

Disk /dev/sdb: 393 MB, 393837568 bytes
223 heads, 46 sectors/track, 74 cylinders

Partition 1 has different physical/logical beginnings (non-Linux?):
     phys=(0, 2, 3) logical=(0, 2, 37)
Partition 1 has different physical/logical endings:
     phys=(47, 222, 46) logical=(74, 217, 13)

And cfdisk:
FATAL ERROR: Bad primary partition 0: Partition ends in the final
partial cylinder


Have I missed something? Any ideas?

Thanks
