Libguestfs - Aug 2014 - Re: libguest-test-tool error report

Hello Rich,

Well, I did give that a try.  But it is back to being unable to access kvm (log
attached).  It did make the qemu error go away.

Thanks,
Mark

Maybe I can virtualize my disk image maker.
I should have mentioned that it's possible to create the disk image in a
compatible mode.  You have to use the `compat=0.10' option (see qemu-img man
page for where to put that).  However once you've created the disk image it
is my understanding that you cannot `downgrade' it.

This is the same problem as before.  KVM is broken.  Remove the
/dev/kvm file to make it fall back to software emulation.

Hello Rich,

Well, you were correct.  I removed the /dev/kvm and it did a lot more.  Sadly, I
cannot tell if it was successful.  The output file is the same size as when I
started, so I am hesitant to declare success.

Let me know what you think. 

Thanks,
Mark
