Hi All, I am trying to evaluate whether centos-4.8 system container work on Fedora-19 machine or not. Host machine : Fedora 19 Guest (LXC container) : CentOS4 .8 For creation of of container i followed following steps, 1. Installed libvirt packages on fedora19 2. For installation of rootfs using yum, I have created the LOCAL YUM REPO using CentOS-4.8 ISO files 3. Created rootfs using yum 4. Made changes in container xml file required for system container 5 .Define container using container xml file Whenever I start system container it get started successfully but when I am trying to access it using console then It show errors regarding /etc/fstab files and filesystem corruption. I am not able to access the container. Refer below for container xml file and error message, contents of xml file for Centos container, *Centos4_8.xml:* <domain type='lxc'> <name>BasicCentos</name> <memory unit='KiB'>102400</memory> <currentMemory unit='KiB'>102400</currentMemory> <os> <type>exe</type> <init>/sbin/init</init> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/libexec/libvirt_lxc</emulator> <filesystem type='mount' accessmode='passthrough'> <source dir='/lxc/centos4.8'/> <target dir='/'/> </filesystem> <interface type='bridge'> <source bridge='br0'/> </interface> <console type='pty' port='0'></console> </devices> </domain> ------------- *ERROR LOG* When trying to access container using CONSOLE command, virsh # console BasicCentos Connected to domain BasicCentos Escape character is ^] INIT: version 2.85 booting /etc/rc.d/rc.sysinit: line 36: [: /sys/fs/selinux: binary operator expected Setting default font (): [ OK ] Welcome to CentOS release 4.8 (Final) Press 'I' to enter interactive startup. hwclock: KDGHWCLK ioctl failed, errno=25: Inappropriate ioctl for device.
