...pdated XML file.
When I execute "id" command to know if root user inside the container has

# id -u root

Re: User Namespace in LXC
...espace
[*] PID Namespaces
[*] Network namespace
There is no User Namespace support. So do I need to patch the kernel for
user namespace support? What should I do in order to get user namespace
working?
Following are my system details:
OS: Fedora 19
Kernel: 3.9.5
Thanks and Regards,

I tried creating a file inside the container with root user. When I checked
uid of the file on the host,

pinVcpu not working
Hi all,
I am working with libvirt and I am trying to set cpu affinity. Now I can always use
virsh vcpupin <domain_name> <vcpu> <pcpu>
to pin vcpus to pcpus. I want to do it using Python API. Now, there is function pinVcpu which is supposed to do that. But this is not working. For example I gave
dom.pinVcpu(0,1)
but still my vcpu affinity is for all the pcpus. The

Check memory inside a container
...emory" and "current memory" as 256
MB.
Now I want to check the memory inside the container, but whenever I run top
command or try to cat /proc/meminfo, it shows host machine's memory which
is 3GB.
So is there any command by which I can check containers memory?

Re: pinVcpu not working
Hi Peeyush,
If we want to pin vcpu1 of a domain to CPUs 3 and 4, we need to pass:
dom.pinVcpu(1, (False, False, False, True, True, False....[and so on, til
number of logical CPUs of host]))
Can you please check this?

If your configure file is right and the libvirt_lxc doesn't throw out error message,
it's a bug we should fix.
