hi all,
The domain config file:
# cat b.xml
<domain type='lxc'>
<name>b</name>
<memory>32768</memory>
<os>
<type>exe</type>
<init>/bin/sh</init>
</os>
<vcpu>1</vcpu>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash&!
gt;
<devices>
<emulator>/usr/libexec/libvirt_lxc</emulator>
<filesystem type='mount'>
<source dir='/data/lxc/centos6'/>
<target dir='/'/>
</filesystem>
<interface type='network'>
<source network='default'/>
</interface>
<console type='pty' />
</devices>
</domain>
then define it:
# virsh --connect lxc:/// define b.xml
Domain b defined from b.xml
then start:
# virsh --connect lxc:/// start b
error: Failed to start domain b
error: internal error guest failed to start: 2012-10-10 09:56:17.369!

It's the filesystem mount section that cause this problem. The tutorial says the path '/data/lxc/centos6' should be "
private root filesystem (perhaps hand-crafted using busybox, or installed from media, debootstrap, whatever)", but I am not quite clear about what this path should be. In my case, the "/data/lxc/centos6" is the root of template downloaded from
http://wiki.openvz.org/Download/template/precreated.
# ls

in boot dev etc fastboot home lib media mnt opt proc root sbin selinux srv sys tmp usr var
Can someone elaborate what should <source dir='/data/lxc/centos6'/> be?
many thanks
