Title:
  kvm crash when writing on disk

Status in QEMU:
  New

Bug description:
  When running the following command:

  /usr/bin/kvm -S -M pc-1.0 -cpu qemu32 -enable-kvm -m 1024 -smp
  1,sockets=1,cores=1,threads=1 -name winxp -uuid f86ef88f-b90e-699a-

  cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5

  
  running a windows installation (for instance, it has crashed with other OS), 
when the guest OS installer has reached 60% of the copying files process, the 
following errors can be found, and KVM gets Force Closed (i am recollecting 
errors from different times I have tried to references to memory positions may 
vary)

  syslog:

  Nov 26 19:46:59 mikeboxx kernel: [2254718.689953] kvm6983 general

  The linux kernel running is this one:

  x86_64 x86_64 GNU/Linux

  Libvirtd versions are these:
  address@hidden:/home/ebox-remote-support# dpkg -l | grep libvirt
  ii  libvirt-bin                          0.9.8-2ubuntu17.4

      library for interfacing with different virtualization systems

  and KVM - QEMU versions are these ones:

      qemu utilities


  I have checked bug  #1022901 in
  https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1022901  due
  to the similarity of the error "internal error End of file from
  monitor", but the sintoms are not the same as long as the partition
  where the img file resides has plenty of space and so does the img
  itself:

  address@hidden:/home/ebox-remote-support# df -h
  Filesystem      Size  Used Avail Use% Mounted on
  /dev/sda1       226G  3.4G  211G   2% /

  address@hidden:/home/ebox-remote-support# qemu-img info 
/var/lib/zentyal/machines/winxp/winxp.img 
  image: /var/lib/zentyal/machines/winxp/winxp.img
  file format: qcow2
  virtual size: 11G (11559501824 bytes)
  disk size: 384M
  cluster_size: 65536

  
  Can you help us to solve this? Case you needed any information else, please 
do not hesitate to ask for it
