And, there's a particular reason to use LXC? </div> I'm not an expert, but if you just want to start using KVM and install a VM I can help you through a simpler method.

I compiled libvirt by doing: $ ./configure --with-selinux=no --with-gnutls $ make $ sudo make install Everything works fine and are installed under /usr/local Then I started the libvirtd manually and try to start a linux container that has the following configuration: $ virsh -c lxc:/// dumpxml lxcvm1 <domain type='lxc'> <name>lxcvm1</name> <uuid>168edaae-e3b5-2d06-7c65-9aa444a6f234</uuid> <memory unit='KiB'>2097152</memory> <currentMemory unit='KiB'>2097152</currentMemory> <vcpu placement='static'>1</vcpu> <os> <type arch='x86_64'>exe</type> <init>/bin/sh</init> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/local/libexec/libvirt_lxc</emulator> <filesystem type='mount' accessmode='passthrough'> <source dir='/home/thouveng/lxc_dir/lxcvm1/rootfs'/> <target dir='/'/> </filesystem> <console type='pty'> <target type='lxc' port='0'/> </console> </devices> </domain> When I start the container I have the following error: $ virsh -c lxc:/// start lxcvm1 error: Failed to start domain lxcvm1 error: internal error guest failed to start: PATH=/bin:/sbin TERM=linux container=lxc-libvirt container_uuid=168edaae-e3b5-2d06-7c65-9aa444a6f234 LIBVIRT_LXC_UUID=168edaae-e3b5-2d06-7c65-9aa444a6f234 LIBVIRT_LXC_NAME=lxcvm1 /bin/sh error receiving signal from container: Input/output error The libvirtd is started with info option so I can see: 2013-04-03 08:49:20.167+0000: 17046: error : virNetSocketReadWire:1362 : Cannot recv data: Connection reset by peer 2013-04-03 08:49:20.267+0000: 17051: error : virLXCProcessStart:1248 : internal error guest failed to start: PATH=/bin:/sbin TERM=linux container=lxc-libvirt container_uuid=168edaae-e3b5-2d06-7c65-9aa444a6f234 LIBVIRT_LXC_UUID=168edaae-e3b5-2d06-7c65-9aa444a6f234 LIBVIRT_LXC_NAME=lxcvm1 /bin/sh error receiving signal from container: Input/output error In libvirtd.conf I have: auth_unix_ro = "none" auth_unix_rw = "none" auth_tcp = "none" auth_tls = "none" And in libvirt.conf everything is commented.
