hardware interrupts continuously 10% to 20% on VM

hardware interrupts continuously 10% to 20% on VM

hardware interrupts continuously 10% to 20% on VM

(OP)
running esx 3.5

have a windows 2003 server on it that is as slow as molasses in wintertime.

used sysinternals process explorer to see that it is showing continuous CPU of 10% to 20% on hardware interrupts on this VM.

what would cause this on a virtual machine?

RE: hardware interrupts continuously 10% to 20% on VM

Have you installed the latest VMtools on the guest?  Which Update build are you running?

RE: hardware interrupts continuously 10% to 20% on VM

(OP)
we are on 3.5.0 build  81946.

it does have the latest version of vmtools.

VMware asked us to apply patch Install patch esx-2007-08-02--15.27.10414.tgz which addresses multimedia timer issues

havent done that yet, probably have to wait until the weekend.
 

RE: hardware interrupts continuously 10% to 20% on VM

You are currently running a pre-Update 1 build.  ESX 3.5 has been updated to Update 4 (plus some post update 4 patches).

You should probably update to at least Update 4 (especially since anything older than Update 4 falls out of support soon).

Update 5 now.

-------------------------------

If it doesn't leak oil it must be empty!!

RE: hardware interrupts continuously 10% to 20% on VM

(OP)
we havent updated before, is it very difficult?
any "gotchas" we need to watch out for?

RE: hardware interrupts continuously 10% to 20% on VM

Oh, didn't know Update 5 was out. Guess it's time to patch our two remaining 3.5 servers.

Chipper, It is a pretty easy process.  Upload the zip file to the ESX server, decompress it an run the update script on the host.  You'll then need to update the VMware Tools on each guest.

The instructions are on the VMware website.
