Hi, all,
I used lxc-tools to create a linux container. I am trying to transfrom LXC container configuration into a domain XML fragment using the following command:

$ virsh -c lxc:/// domxml-from-native lxc /var/lib/lxc/my_conatiner/config

However, I get the error message,
error: this function is not supported by the connection driver: virConnectDomainXMLFromNative

It seems that virConnectDomainXMLFromNative is not supported in libvrit LXC driver. However, I find the command in the official documentation of libvirt. Besides, my libvirt's version is 1.2.2(the latest version).

I wonder whether I can convert LXC container configuration into a domain XML fragment using domxml-from-native? If I can't, how cant I translate it? 

I care about the rules in my LXC container configuration file, such as:
lxc.aa_profile = unconfined

lxc.cgroup.devices.deny = a
# Allow any mknod (but not using the node)
lxc.cgroup.devices.allow = c *:* m
lxc.cgroup.devices.allow = b *:* m
lxc.cgroup.devices.allow = b 7:* rwm

I just don't know how to express the rules above using xml format. Please help! Thanks!

Best Regards,
Du Jun
