Here missed "add kernel modules". Did you test 1.15.11-1 here http://libguestfs.org/download/binaries/ubuntu1110-packages/ ? I just tested on ubuntu-11.10 x86_64, but didn't see this error, can you test with the 1.15.11-1 package again and send the result here? Thanks -Wanlong Gao

This is a bug in qemu 0.15, fixed in qemu 1.0 (although 1.0 introduced another bug which prevents libguestfs from working out of the box there too). If you recompile libguestfs from source then it will detect this qemu problem at ./configure time and add some code to work around it. However the binaries on the website weren't compiled this way. In Fedora we patch around many qemu bugs, so it's worth keeping an eye on our qemu packages: http://pkgs.fedoraproject.org/gitweb/?p=qemu.git Here is the patch you need to qemu 0.15 which fixes the above bug: http://pkgs.fedoraproject.org/gitweb/?p=qemu.git;a=blob;f=qemu-Allow-to-leav...

Thanks Rich and Gao. I have solved this issue by update qemu-kvm from 0.15 to 1.0 version. Zhi Yan, Liu
