Hello, one of my VM is running CentOS-5.8. Most of the time, it's load avg.
is high. It has 4 gigs memory and Xeon 3.48 GHz single processor.
I am not sure, why this "exact" VM is showing high load all the time. Same
softwares with same configuration ( 4 gigs memory + even 2.66 GHz single
processor ) are not throwing such high load averages.
I searched processes which are running, those are necessary so I can't kill
them actually ( and moreover, these processes are running in other VMs too
).
Load Average is most of the time > 1.5
Any suggestion?

Hi,
Pl clarify the below points.
1. Pl mention the ESX version.
2. CentOS is 64bit?
Pl check the following options are enabled in the ESX where your Centos VM
resides.
1. Hyperthreading option is enabled in the ESX server. Check in the BIOS or
in the Vcenter select that particular esx and go to summary page. The HT
option should be active. If not enable the HT option in BIOS.
2. Pl check any reservation for cpu is allocated to some other VM, which in
turn cause the slow to other vm.
3. Select the CentOS VM, go to edit settings & go to resources. In Adv.cpu
HT core sharing mode should be "Any"
Thanks,
