[Xen-users] Xen questions (Be kind)



HI, I'm new here and very new to Xen so please be kind.

I have inherited a CentOS dedicated server with xen, basically running 1 vps and I am trying to optimise it as it seems to me that the 1 VPS is not using anywhere near what is available.

When I look at TOP command on the host machine the load average is very good 0.31, 0.25, 0.16 but when I login to the VPS and look at TOP the load average is : 8.49, 7.61, 8.21.

This is the xen list of vps's

Name                                      ID Mem(MiB) VCPUs State   Time(s)
Domain-0                                   0      405     2 r----- 778902.7
saturn 1 7599 2 r----- 20162599.6

As you can see there is only two vps's the Domain-0 (which as I gather is meant to be there and uses very little resources) and our main VPS..

I want Saturn to basically utilise as much resource as it can.

here is xm top in case that makes a difference.

xentop - 14:44:31   Xen 3.1.2-194.17.1.el5

Thanks for your help in advance.
