LXC container shows host CPU and buggy memory

[encore]

Hi,

htop on my debian 9 LXC CT shows two cores of the hostserver and its physical CPU usage.
Furthermore htop shows 4/2 gb memory usage, free -m shows the true memory usage.
AVG load of the hostserver is also shown.

Is there a workaround for it to really show the used resources by this LXC CT instead of the node usage?

see https://pve.proxmox.com/pve-docs/pve-admin-guide.html#pct_cpu and https://bugzilla.proxmox.com/show_bug.cgi?id=1870

but please be aware that it is usually trivial to get information about the hypervisor host via the kernel (via syscalls, sysfs, ...) - lxcfs is mainly a cosmetic solution.

Hi Fabian,

Means the avg load display will be fixed shortly? Is there an ETA?

And whats about the memory usage and core usage in htop?
- Memory usage is completly random and shows a value higher than maximum
- core usage shows core usage from node view

Hi Fabian,

no, it means that there is an (optional) upstream solution that we will take a look at and MAYBE implement/enable.

And whats about the memory usage and core usage in htop?
- Memory usage is completly random and shows a value higher than maximum
- core usage shows core usage from node view

it's not completely random, there are some scenarios where the display is wrong though, and those are not easily fixable without creating other similar issues.

the core issue is documented (check the first link I posted).
