Hi,
I have updated to CS 4.2 (not sure that my problem has to do anything with
that...)
I have RAM overprovisioning level of 2 on Cluster level.
And after I start VM with compute ofering of 2GHZ (1x2gHz) and 2GB of ram,
it does invoke qemu-kvm with good parameters (2048M), but inside my VM when
doing top, or free -m, it reports rougly 50% of that amount:
Here is the ps axu | grep vname #from host on which VM is running:

Same for top.
Not sure what is happening, has to do something with RAM overprovisioning
factor ?
How is this possible, when qemu-kvm parameteres seems fine (-m 2048)
Thanks,
