Also you can give it a try by enable "Para Virtualization" option for these 2 linux VMs.<BR />This will improve your system performance.<BR /><BR />Also when you talking about the loads here i guess you are refuring to VMs load. Check the Status of the ESX load also to identify any resource bottle necks.<BR /><BR />Also if this is a trial version that you have upgraded to license dont forget to add all the patches for ESX.<BR /><BR />This is also valid for the Linux OS as well<BR /><BR />Good Luck..!<BR /> <BR /> Wed, 22 Oct 2008 03:17:41 GMT Nuwan Alwis 2008-10-22T03:17:41Z https://community.hpe.com/t5/operating-system-linux/virtualization-of-linux-rh4-on-vmware-3-5/m-p/4291420#M34262 Hi, <BR />I have a problema on vmware 3.5 and linux rh 4. I virtualized two linux servers that have the funtion of OAS (Oracle application server). The enviroment is fine, but i saw more load on the % Use CPU. Before the virtualization (Servers IBM with OAS), the system cpu load was between 5% and 8% and the user cpu load was between 10% and 17%, but now only the system cpu load are between 20% and 34% percent and the user cpu load between 15% and 20%. I am very worried about the system cpu load, because this is very high. I don't know why!.<BR />Somebody have experience with this type of virtualization whit rh-OAS and vmware. Please some recomendation??.<BR /><BR />My hardware is hp blade cx7000.<BR />Thanks, Tue, 21 Oct 2008 16:45:53 GMT https://community.hpe.com/t5/operating-system-linux/virtualization-of-linux-rh4-on-vmware-3-5/m-p/4291420#M34262 David_711 2008-10-21T16:45:53Z https://community.hpe.com/t5/operating-system-linux/virtualization-of-linux-rh4-on-vmware-3-5/m-p/4291421#M34263 I have seen a similar problem with one of our servers. I think that the problem is I/O related.<BR /><BR />I noted also that RHEL 32 bits causes less load than 64 bits on vmware in my tests.<BR /><BR />Ensure that you have vmware tools intalled. Ensure that you have the latest kernel available.<BR /><BR />Suddenly, the current Red Hat kernel does not provides support for vmware paravirtualization. I tested with a linux.org kernel, but I must admit that the results where similar.<BR /><BR />Probably, you will get better performance with XEN virtualization.
