[Libguestfs] libguest-test-tool error report

Hello,

I am trying to use virt-resize.  It does not work.  I set the debug environment
variables and ran libguestfs-test-tool.  The following is its output.  I am
running RHEL 6.5 desktop with kernel:
Linux hustedm-lnx4 2.6.32-431.5.1.el6.x86_64 #1 SMP Fri Jan 10 14:46:43 EST 2014
x86_64 x86_64 x86_64 GNU/Linux

Please let me know what I have missed.

Thanks,
Mark

This is not good!  Does KVM generally work on this machine?  Do you
have VirtualBox or another hypervisor running at the same time?

If you were running a later version of libguestfs then I would
recommend setting:

  export LIBGUESTFS_BACKEND_SETTINGS=force_tcg

Unfortunately that doesn't work on 1.20 (added in 1.26) and doing the
equivalent in RHEL 6 is rather involved.

If KVM is broken or there's another hypervisor running you could
also try making /dev/kvm unreadable (chmod 0 /dev/kvm <or> rm /dev/kvm).

Re: [Libguestfs] libguest-test-tool error report

Hello Rich,

I am not sure if KVM ever ran.  I put VirtualBox in it because I have never done
virtualization before and found some instructions for VB.  That said, I might
have naively shut something off because I didn't know any better.  No VB was
not running at the time.  I thought of that and turned it off.  Though, I bet
the services are still up.

What is the standard kvm service?  I could check to see if it is running
properly. And we could go from there.

Thanks for the quick response!
-Mark

Thanks,
