@weizhouapache, very interesting. I checked the resource utilization of the
Java process on one of the hosts currently exhibiting the issue, and this was
the output:
```
root@host3:/home/zgadmin# pid=$(pgrep -f /usr/bin/java)
echo "CPU: $(ps -p $pid -o %cpu --no-headers)%"
echo "MEM: $(ps -p $pid -o %mem --no-headers)%"
echo "FD: $(ls /proc/$pid/fd 2>/dev/null | wc -l)"
echo "Threads: $(ps -L -p $pid -o tid --no-headers 2>/dev/null | wc -l)"
echo "Conn: $(ss -tanp | grep "pid=$pid" | grep ESTAB | wc -l)"
CPU: 73.9%
MEM: 0.1%
FD: 253
Threads: 134
Conn: 1
```
But I had a test all-in-one ACS on ubuntu 24.04 with libvirt 10.0.0, but I
couldn’t reproduce the issue I’m seeing in the production environment. I
repeatedly ran your test script:
```
for i in `seq 1 20`;do
cmk deploy virtualmachine name=L2-wei-test-$i serviceofferingid=xxx
zoneid=xxx templateid=xxx networkids=xxx & >/dev/null;
sleep 2;
done
```
to generate load, and the results were consistently fast:
```
mysql> select id,name,created,update_time,(update_time-created) from
vm_instance where removed is null and name like "L2-wei%";

```
I'll try to create a full environment consisting ceph and multiple kvm host
on a test environment to see if i can replicate the issue there and see if
libvirt 10.6.0 fix it, later this week.
