[Xen-users] Experiencing memory leak of xend/qemu-dm

[dongkyu lee <dongq.lee@xxxxxxxxx>]

We have created more 200 VMs and run them for almost one year. 
There have been no xend memory problems with the servers which contain only linux vms.
Recently, we decided to use Windows VMs. After that, we have experienced lack of dom0 memory serveral times
because dom0 memory usage (because of xend) has increased linearly and dom0 became out of memory.
(Eventually OOM killer make the server reboot)

We created six windows VMs to watch memory usage of xend for a week. Now xend is using 4.6GB memory (out of 32GB)
It is 22% usage of total memory size. Monitoring system shows its memroy usage has increased gradually (perfectly increasing linear line)

Any comments would be greatly appreciated. 

Thank you in advance.
