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. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
