Re: [Xen-users] Xen not viewing all memory available on host



Thanks for the explanation  ...
I was getting worried about it!

Other memory is allocated to DomU, so Dom0 only has 39G, you can use ‘xl info’ to see total memory:

 

# xl info

total_memory           : 65506

free_memory            : 6667

 

free_memory is for DomU.

主题: [Xen-users] Xen not viewing all memory available on host

 

Hello Guys, 

 

Despite having 96GB of memory available on my hardware the system only shows  39GB available? 

Does anyone have seen this behavior before?

 

Running Xen 4.4.1 (must be this version!)
