VM does not assign all available memory to Server 1.5Gig missing

user4862131Jan 21 2010 — edited Feb 26 2010
We have a number of different servers all with 5gig memory. However I can only assign 3046m to the VM

I am running on Oracle VMs with Oracle Enterprise Linux 64bit on these machines. However there is a large discrepency with the Memory on the VM and the actual memory in the machines, here is some information I have:

On the server itself if I do free -m gives me:
Total: 563 used: 205 free: 357

xm info|grep mem gives:
total_memory : 5046
free_memory : 1343

dmesg |grep mem gives
vmalloc area: e4800000-feffe000, maxmem 377fe000
Memory: 495616k/584704k available (2051k kernel code, 80632k reserved, 818k data, 176k init, 0k highmem)

My understanding of the above is that the Machine is allocated 0.5gig and the Current VM is assigned 3gig leaving almost 1.5gig unassigned and free. However, if I log into the VM Manager and try and assign the extra free memory to the VM, I get an error saying the maximum I can assgin is 3046.

In VM Manager I check the sever tab for the machine the VM is assgined to I can see:
Memory Size(MB): 3046.

xm list gives the following information, which I think sort of confirms my assumptions:
Name ID Mem VCPUs State Time(s)
70_ebstestapps 1 3046 2 -b---- 303.6
Domain-0 0 563 4 r----- 83.4

I am guessing this is my problem. Although the memory is available on the machine, when creating the server with VM Manager it is only picking up 3046!! I am unable to edit this value and have tried rebooting the server but the same value appears.

How can I fix this problem? any help in this would be greatly appreciated.
