Libguestfs - Jan 2014 - Re: libguestfs hanging on CentOS 6.2

Hi,

libguestfs is hanging on my CentOS 6.2.
Here is the output of the libguestfs-test-tool:
http://pastebin.com/Kh5H1Wyj

Any hint?

Thanks

Just in case, here is also the output after exiting the 
libguestfs-test-tool:

...

The next line here should be:

  febootstrap: picked /sys/block/vdb/dev as root device

So for whatever reason febootstrap cannot find the appliance disk.  It
is added correctly on the qemu command line.

Versions installed (from IRC chat) were:

  libguestfs-1.20.11-2.el6.x86_64
  libguestfs-winsupport-1.0-7.el6.x86_64 

(ie. from RHEL 6.5)

My suggestion is that you're going to have to upgrade the kernel and
qemu (at least) to the same as from RHEL 6.5, since we don't test
mixed old/new packages.  Given that 18 months passed between 6.2 & 6.5
it could be a bug in just about anything.

Note that libguestfs will use the newest kernel in /boot, so you can
install the newer kernel even if there's some (eg hardware) problem
keeping you on the old host kernel.
