I am starting the system container without "/"  directory So that it can share the host /bin /sbin /lib and /lib64 and i have sepeartely mounted /var, /etc and /usr directory for the container

Below is xml file

 <domain type='lxc'>

<name>test6</name>

<memory>102400</memory>

<os>

  <type>exe</type>

  <init>/sbin/init</init>

</os>

<vcpu>1</vcpu>

<clock offset='utc'/>

<on_poweroff>destroy</on_poweroff>

<on_reboot>restart</on_reboot>

<on_crash>destroy</on_crash>

<devices>

  <console type='pty'/>

  <emulator>/usr/libexec/libvirt_lxc</emulator>

  <filesystem type='mount' accessmode='passthrough'>

    <source dir='/lxc/test6/etc'/>

    <target dir='/etc'/>

  </filesystem>

  

  <filesystem type='mount' accessmode='passthrough'>

    <source dir='/lxc/test6/var'/>

    <target dir='/var'/>

  </filesystem>

  <filesystem type='mount' accessmode='passthrough'>

    <source dir='/lxc/test6/usr'/>

     <target dir='/usr'/>

  </filesystem>

  <filesystem type='mount' accessmode='passthrough'>

    <source dir='/pg_data/'/>

    <target dir='/pg_data'/>

  </filesystem>

  <filesystem type='ram' accessmode='passthrough'>

    <source usage='0' units='KiB'/>

    <target dir='/dev/shm'/>

   </filesystem>

   <interface type='bridge'>

     <source bridge='br0' />

   </interface>

</devices>

</domain>

when i start the container it get start , but when i try to access console it get stuck

But when i mount the "/" in xml it works, i have also share host /bin,/sbin, /lib and /lib64.

as i am new , can anyone explain me why my test6 container get stuck?

And in system container if we need to share host filesystem y we need to mount them explicitly?

Thanks,
