Hi,
The issue is still there?
Yes, yet.
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?
Regards,
Gesiel

Appearly
the problem is that normally the application load
many short files
(ex:
DLLs) and these files take a long time to load,
generating a slowness.
Did you check/test your network connection?
Do you have a fast network setup? _______________________________________________

Hi,
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
computer?
Find the line with *max_files = *which defines how many FD qemu can have.
