Hi folks!
i created a server with this XML file:

I would expect it to have 2 cpu cores and 1 GB RAM.
The RAM config works.
The CPU config does not:
[root@lxctest1 ~]# lscpu
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 24
On-line CPU(s) list: 0-23
Thread(s) per core: 2
Core(s) per socket: 6
Socket(s): 2
NUMA node(s): 2
Vendor ID: GenuineIntel
CPU family: 6
Model: 62
Model name: Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz
Stepping: 4
CPU MHz: 2399.950
BogoMIPS: 4205.88
Virtualization: VT-x
L1d cache: 32K
L1i cache: 32K
L2 cache: 256K
L3 cache: 15360K
NUMA node0 CPU(s): 0,2,4,6,8,10,12,14,16,18,20,22
NUMA node1 CPU(s): 1,3,5,7,9,11,13,15,17,19,21,23
It gives me all CPU's from the host.
I also tried it with
<cpu>
<topology sockets='1' cores='2' threads='1'/>
</cpu>
That didnt help too.
I tried to modify the vcpus through virsh:
#virsh -c lxc:/// setvcpus lxctest1 2
error: this function is not supported by the connection driver:
virDomainSetVcpus
Which didnt work too.
This happens on:
Centos 7
Kernel: 5.1.15-1.el7.elrepo.x86_64
#virsh -V
Virsh command line tool of libvirt 4.5.0

and also on
Fedora 30

Can anyone please tell me what i am doing wrong here ?
Thank you !
