HI, All. I face problems when try to use libguestfs in new ubuntu 11.10. 1) My current version of libguest (1.12.0, binaries taken from libguestfs site) can't boot vm with new kernel. You can find log of libguest-test-tool in attachment. I try force it to boot 2.6.38-11 kernel instead of 3.0.0-12 (which is default), but get the same result (error) 2) I can't compile libguestfs from sources: make libguestfs-1.12.7 leads to: .........
