1. Find the Qemu pid with "ps ax"
2. Collect the FD used by the Qemu with "ls /proc/$pid/fd/ | wc -w" //
$pid is the Qemu pid
3. cat /proc/$pid/limits | grep -E 'open files | processes'
Do you have the configuration file */etc/libvirt/qemu.conf *on the

The issue is still there?
I have met an IO peformance issue recently and
found that the count of
the max fd for the Qemu/KVM was not bigger enough, the fd for Qemu/KVM was
exhausted, the issue was solved after increasing the count of the max fd.
How check and increase max fd for qemu? Can you give-me way?
