Comment # 2 on bug 1070478 from Walddys Emmanuel Dorrejo C�spedes

Thank you for you fast response and the only correct answer for this problem
over all the internet.

i am too noob on the side of working with the xml, so can you said me where put
this line

device virtio-blk-pci,drive=vda,share-rw=on
# share-rw=on

This is the script to add the shareable device

<disk type='file' device='disk'>
  <driver name='qemu' type='raw'/>
  <source file='/home/wedc/VMs/crs.img'/>
  <target dev='vdb' bus='virtio'/>
  <shareable/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</disk>

Thank you for the help.
