We are running a bunch of OVM in the office for our demo systems, it’s very cool. I’m quite new to all of this, so apologies for the numpties view.
Above is the console that you do all your VM management from. It’s pretty basic, but you can get the job done. We have 10 virtual machines listed.
You can see the actual IRON that you’re using under the servers tab:
So I want to see what is going on on my host in terms of disk and CPU. One of the guest machines is going bonkers and I want to see what the host is doing… What do I do?
ssh (via putty [best software in the world{except for vi}]) to the server listed under the servers tab and execute:
xm top
This will give you a view of what the various machines are doing behind the scenes:
Note that top gives you nothing, you need to use the xm top function.
xm – xen management
from man:
DESCRIPTION
The xm program is the main interface for managing Xen guest domains. The program can be used to create, pause, and shutdown domains. It can also be
used to list current domains, enable or pin VCPUs, and attach or detach virtual block devices.
