Hi All, I want to build libguestfs in my RHEL5.3 box which has already KVM installed, what I am using are: libguestfs-1.0.65.tar.gz fakechroot-2.9-23.el5.x86_64.rpm fakechroot-libs-2.9-23.el5.x86_64.rpm fakeroot-1.11-19.el5.x86_64.rpm febootstrap-2.4-1.el5.noarch.rpm squashfs-tools-3.0-4.x86_64.rpm Then I ran "./configure" in libguestfs-1.0.65, everything was OK, but when I ran "make": ... + read pkg + exec + febootstrap -i augeas-libs -i iputils -i kernel -i MAKEDEV -i ntfsprogs -i scrub -i udev -i util-linux-ng -i bash -i binutils -i coreutils -i dosfstools -i file -i grub -i lsof -i lvm2 -i module-init-tools -i net-tools -i ntfs-3g -i procps -i strace -i zerofree -u updates-released-f11 fedora-11 initramfs febootstrap | 3.8 kB 00:00 6a8bfab8ebcbc79f9827f5b16bc1bd1573c068f141bf47c6f216e72dd8b60ff0-primary.sqlite.bz2 | 10 MB 03:21 http://ftp.riken.jp/Linux/fedora/releases/11/Everything/x86_64/os/repodat...: [Errno -3] Error performing checksum Trying other mirror. 6a8bfab8ebcbc79f9827f5b16bc1bd1573c068f141bf47c6f216e72dd8b60ff0-primary.sqlite.bz2 | 10 MB 02:36 http://ftp.jaist.ac.jp/pub/Linux/Fedora/releases/11/Everything/x86_64/os/...: [Errno -3] Error performing checksum Trying other mirror. 6a8bfab8ebcbc79f9827f5b16bc1bd1573c068f141bf47c 82% [=============================== ] 74 kB/s | 8.6 MB 00:25 ETA ...
