[Xen-users] Xen & free_memory

[Evgeniy Sudyr <eject.in.ua@xxxxxxxxx>]

Hello,

I noticed that on my server xm info reports that only 125 MB are available.

There is it:

But free shows me that I have 606 MB available.

I killed some processes and again xm info shows me that only 125 MB
available, but free shows additional memory space which was freed.

Question: what it mean? I dig documentation, but found nothing :(.
There is memory limits somewhere in configs ?

Thanks,
Evgeniy
