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.
