Re: [Lxc-users] Regarding lxc tools and libvirt (virsh).
Thanks for the reply Daniel. I have another issue. I am creating a Domain using libvirt XML. In order to mount the host's '/home/srikanth' directory to the new container's '/' directory, my XML format is shown below: domain type='lxc' id='1' namecontainer1_vm/name memory50/memory os typeexe/type init/bin/sh/init /os vcpu1/vcpu clock offset='utc'/ on_poweroffdestroy/on_poweroff on_rebootrestart/on_reboot on_crashdestroy/on_crash devices emulator/usr/libexec/libvirt_lxc/emulator filesystem type='mount' source dir='/home/srikanth'/ target dir='/'/ /filesystem console type='pty' / /devices /domain With the above libvirt XML, Domain is defining, but not starting. When I issue the start command it's saying Domain started, but showing shut off status. If I changed the target directory(traget dir='/'/) from '/' to '/home/container1'(traget dir='/home/container1'/), the domain is starting normally and I am able to see the contents in the target directory. Can you please let me know, how can I set the target directory to '/'? By the way, I am using libvirt version o.7.6.
