Hi

I'm trying to run libguestfs-test-tool which in turn is using kvm utility
on powerpc ubuntu.Below are the logs when I'm trying to run the
libguesfs-test-tool utility..

What machine are you running on?  What kernel version?

Hi Paolo

I'm running this on ubuntu with powerpc arch with kernel
3.8.13-rt9-QorIQ-SDK-V1.4.


Thanks

I'll note that this is a fairly old kernel for PowerPC KVM.  However, 
the problem looks like libguestfs supporting only "server" PowerPC (also 
known as "book3s"), not "embedded" ("booke").

Please don't top post.

You're running on QorIQ which is a Freescale chip. The pseries target only works on IBM PPC chips.

The target you're looking for is ppce500:

  $ qemu-system-ppc64 -M ppce500 -nographic -kernel uImage ...

I don't know about the status of libvirt in your sdk version, but I'm sure Stuart does, so let's ask him ;).

libvirt is supported in Freescale SDK 1.4 in the Yocto-built rootfs, so I
would expect anything that uses libvirt interfaces to work there.  But, we
haven't specifically tested libguestfs.

However, it looks like you may not be using the SDK Yocto rootfs, but a
ubuntu rootfs.  In that case there may be a issue with the ubuntu libvirt.
There are some patches that we apply to libvirt that you will find only in the
Freescale SDK...you can find them if you look at the libvirt Yocto
recipe.

Hi Stuart.

Thanks for the information.I need to run libguestfs on powerpc ubuntu.How
can i do that?

Are there any patches for the same.

I think you will have to build/install libvirt yourself on ubuntu with the
Freescale patches.

For SDK 1.4, you can see the Yocto recipe used here:
http://git.freescale.com/git/cgit.cgi/ppc/sdk/meta-fsl-networking.git/tree/recipes-append/libvirt

...we use the stock Yocto libvirt recipe and and apply 2 patches.

The 2 patches are here:
http://git.freescale.com/git/cgit.cgi/ppc/sdk/meta-fsl-networking.git/tree/recipes-append/libvirt/files

I have not built libvirt from scratch myself, so can't help you there.

Thanks,
Stuart

Hi Stuart

Thanks for the information.I'm able to run libvirt on my system.I need to
run libguestfs on the same powerpc ubuntu.
Can you help me regarding that?

Based on your original description of the problem, I thought the error was that libvirt was starting a PAPR machine instead of an e500 machine.   So my take is that libvirt needed to be rebuilt with the patches to support e500 machines (that I mentioned in my last email).

If you are actually able to start e500 machines successfully with libvirt, then the problem must lie with how libguestfs interfaces to libvirt or something.   I have never used libguestfs, and don’t think I can help you with that.

Thanks stuart  for the help  you have provided me.

The libguestfs is directly related with qemu.
Could you help me regarding qemu with latest version having freescale
patches.

I think that will solve my problem.

Thanks
