Although the LXC is tech preview in rhel6.y, we should make sure the basic application and OS container are available for users in rhel6.y. In addition, whether we will provide virt-bootstrap tool to install OS container instead of febootstrap in rhel6.5?

Full OS containers based on RHEL-6 are explicitly unsupported in RHEL-6. With the sysvinit style init scripts we have in RHEL-6, it is not practical to make the changes required to get standard RHEL6 packages booting in a container. Any full OS container must be systemd based. Thus you can run F19 on a RHEL-6 host, but you'll never be able to do RHEL-6 on any host. In addition do not use febootstrap for creating the install.

Opps, the 'virt-install' command above, should have been the very last thing in that command list.
Please let me know if you wish to retest with the steps from comment #2, otherwise I'll close this NOTABUG.

Hi Daniel, I've tried the steps you mentioned to install a fedora based container and i meet the following issue. 1. cat /etc/yum.repos.d/yum-fedora.conf [main] cachedir=/var/cache/yum/$basearch/$releasever keepcache=0 debuglevel=2 logfile=/var/log/yum.log exactarch=1 obsoletes=1 gpgcheck=1 plugins=1 installonly_limit=3 [fedora] name=Fedora $releasever - $basearch failovermethod=priority #baseurl=http://download.fedoraproject.org/pub/fedora/linux/releases/$releasever/Everything/$basearch/os/ mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=$basearch enabled=1 metadata_expire=7d gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$releasever-$basearch [updates] name=Fedora $releasever - $basearch - Updates failovermethod=priority #baseurl=http://download.fedoraproject.org/pub/fedora/linux/updates/$releasever/$basearch/ mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=updates-released-f$releasever&arch=$basearch enabled=1 gpgcheck=1 2. yum -y --nogpg --releasever=19 --config=/etc/yum.repos.d/yum-fedora.conf --installroot=/var/lib/libvirt/filesystems/f19x86_64 --disablerepo='*' --enablerepo=fedora install systemd passwd yum redhat-release vim-minimal openssh-server procps 3. echo "pts/0" >> /var/lib/libvirt/filesystems/f19x86_64/etc/securetty 4. vi /var/lib/libvirt/filesystems/f19x86_64/etc/pam.d/login I can't find the loginuid line. Could you please add the line here. 5. chroot /var/lib/libvirt/filesystems/f19x86_64 /bin/passwd root 6. virt-install --connect lxc:/// --name f19x86_64 --ram 800 --filesystem /var/lib/libvirt/filesystems/f19x86_64,/ Starting install... ERROR internal error guest failed to start: internal error Child process (ip link set veth1 netns 25121) unexpected exit status 2: RTNETLINK answers: No such process Can't install fedora based container. And I'd like confirm if fedora based container are fully supported on RHEL6.5 host. Thank you very much.

I've retested the with latest tree and kernel-2.6.32-422.el6. I could install a fedora based container and login with root and passwd. So close the bug as not a bug.
