Is this normal? > cool, thanks for sharing @TadiosAbebe I just checked my kvm host with libvirt 10.0.0 (running 36 hours without touch) - the CPU usage of java process has increased to 30.6% - It took 0.5 seconds to process GetVncPortCommand and return GetVncPortAnswer - There is indeed a java thread which CPU time is 40 hours (41:00:93) On the kvm host with libvirt 10.6.0 (running 24 hours without touch) - the CPU usage of java process is still 0.5% - It took 0.004 seconds to process GetVncPortCommand and return GetVncPortAnswer - The most CPU time of java threads is 1 hour (1:08:12) > If i restart libvirtd and the CPU time of the java process those process with > high CPU time goes away and the max becomes 0:05:26 > > I'll replace the libvirt with 10.6.0 on the all-in-one instance and see what > changes now. I believe libvirt 10.6.0 is a worthwhile version to test, even though its official packages target Ubuntu 24.10 rather than Ubuntu 24.04. cc @poli1025 @shwstppr @marekhorecny @vgarcia-linube @jgotteswinter @bradh352 @SviridoffA @TadiosAbebe GitHub link: https://github.com/apache/cloudstack/discussions/12450#discussioncomment-15515844 ---- This is an automatically sent email for [email protected].
