Hi, Gao Feng
I've tried what you said, but still exists the problem:
ubuntu@lxc:~$ vir attach-disk instance-0000002c /dev/dm-0 sdb
error: Failed to attach disk
error: Unable to create device /proc/10366/root/dev/sdb: Permission denied
I think finding what it means by saying 'Unable to create device
/proc/10366/root/dev/sdb: Permission denied' is the key.
But anyway, thanks for your help!
Do you have <idmap> configured for your lxc domain?
I just posted a patchset to fix the problem that failed to create device when user
namespace enabled.
BTW, does it work well if you directly write the configuration to the xml of lxc domain?
Thanks
