qemu-system-ppc64 crashes if qemu-slof is not installed

[maimi09]

This problem occurred when I clicked the Search button on the "Find Emulators" of "First Start Wizard" dialog.
However, the buttons in the dialog is still operable state.

In addition, I have test drive can be installed in a real machine Edubutnu 14.04 alpha version.

Thanks for reporting this bug. Trivially reproduced by doing

/usr/bin/qemu-system-ppc64 -net nic,model=?
Warning: Disabling some instructions which are not emulated by TCG (0x0, 0x6)
qemu: hardware error: qemu: could not load LPAR rtas '(null)'

[Serge Hallyn (serge-hallyn)]

(could not test with upstream git because it doesn't seem to compile right now)

[Serge Hallyn (serge-hallyn)]

Please install the package qemu-lsof. That should fix the problem.

We will look into moving qemu-lsof into main so that we can have qemu-system-ppc depend on it.

[Serge Hallyn (serge-hallyn)]

Sorry, I mis-typed. the package to install is:

  sudo apt-get install qemu-slof

[Serge Hallyn (serge-hallyn)]

Fixed since qemu-slof is now in main and depended upon by qemu.
