[lxc-users] BIND isn't recognizing container CPU limits

[Joshua Schaeffer]

I saw this in my log file when I start BIND9 and was a little concerned, since I limit the container to 2 CPU's and this is an unprivileged container:

    Aug  2 16:04:39 blldns01 named[320]: found 32 CPUs, using 32 worker threads
    Aug  2 16:04:39 blldns01 named[320]: using 16 UDP listeners per interface
    Aug  2 16:04:39 blldns01 named[320]: using up to 4096 sockets

>From the container:

    root at blldns01:~# cat /proc/cpuinfo | grep -c processor
    2

>From the host:

    lxduser at blllxd01:~$ lxc config get blldns01 limits.cpu
    2

Why would BIND be able to see all the cores of the host? I can certainly limit BIND to using less threads, but it shouldn't be able to see that many cores in the first place. I'm using LXD 2.15

Thanks,
Joshua Schaeffer
