Public bug reported:

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 139" to try whether the SMB server works. KVM
then hogs the CPU.
