Title:
  kvm smb server hogs cpu guest freeze

Status in QEMU:
  Incomplete
Status in qemu-kvm package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: qemu-kvm

  kvm hogs the CPU reproducibly. I installed an Ubuntu using KVM. I run
  the machine with -net nic,model=rtl8139,macaddr=f0:00:BA:12:34:56 -net
  user,hostfwd=tcp::2223-:22,smb=/tmp/share, sshed into the machine and
  typed "telnet 10.0.2.4 139" to try whether the SMB server works. KVM
  then hogs the CPU.
