[Xen-users] xen not freeing up memory once a VM is removed

["Inception Hosting" <inbox@xxxxxxxxxxxxxxxxxxxx>]

Hi Folks,

 

Wonder is anyone can help shed any light or give me a few troubleshooting steps for this problem.

 

I have just noticed that pretty much all my RAM is taken up and this is not right so as a test I looked at xm info which showed:

 

free_memory            : 122

 

I then deleted test 5 VM’s I have had no use of for quite some time all with between 128 and 256MB of RAM allocated to them and ran xm info again which still shows:

 

free_memory            : 122

 

The XEN version is 4.0.1

I have set the dom0 memory flag to 1024mb

 

If I run xm list and calculate the total memory used by VM’s (All booted up) there is a discrepancy of just over 1GB of RAM that is unaccounted for.

 

Has anyone got any tips for this?

 

OS is CentOS 5.7

Kernel is 2.6.18-238.19.1.el5xen

 

Thanks.
