Hi:
I'm trying to connect with libvirtd with virsh from a remote PC,but only
can establish 1000 connections.
If try more connections,prompt:
"error: failed to connect to the hypervisor
error: Failed to open file '/etc/libvirt/libvirt.conf': Too many open
files"
I tried in another PC,also get the same prompt.
Anybody know why?
There's a limit of 1024 open file handles by default on Linux. You would
have to raise that limit in /etc/security/limits.d/ for your user.

In /etc/security/limits.d/,there is only 20-nproc.conf.
I modified /etc/security/limits.conf,what I added is:
"* soft nofile 81920
* hard nofile 81920"
I also modified /etc/pam.d/login,that I added is:
"session required pam_limits.so"
The output of "ulimit -a" is:
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 385898
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 81920
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 385898
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
What I did is right?
