Description of problem:
Hit error when shutdown 100 VMs and run `virsh domstats` concurrently,
"error: internal error: End of file from qemu monitor
error: Unable to read from monitor: Connection reset by peer".

Version-Release number of selected component (if applicable):
libvirt-6.6.0-6.module+el8.3.0+8125+aefcf088.x86_64
qemu-kvm-5.1.0-9.module+el8.3.0+8182+ac9ced32.x86_64
kernel: 4.18.0-234.el8.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Start 100 VMs
2. Run domstats.sh to get all domain stats on one terminal

1. cat domstats.sh
   #!/bin/sh
   for i in {1..50}

   do
   virsh domstats 2>&1 >>stats.log
   sleep 2
   done

#sh domstats.sh

3. On another terminal, shutdown 100 VMs concurrently

1. for i in $(virsh list --name); do virsh shutdown $i & done

4. Get error in libvirtd.log and on the terminal which is running domstats.sh
-------------------------------------------------------------------

1. sh domstats.sh
   error: internal error: End of file from qemu monitor
   error: Unable to read from monitor: Connection reset by peer
   error: Unable to read from monitor: Connection reset by peer
   error: Unable to read from monitor: Connection reset by peer
   --------------------------------------------------------------------

Actual results:
In Step4, Get error in libvirtd.log

Expected results:
In Step4, No error.

Additional info:

• libvirtd.log
• qemu guest log

• In step2 run `python3 domstats.py`, hit same error.

1. cat domstats.py
   import libvirt
   import time
   conn = libvirt.open("qemu:///system")
   for x in range(1,100):
   print(conn.getAllDomainStats())
   time.sleep(2)
