Hello to everyone,
I've encountered a strange situation: VMware ESXi 4.0.0 is installed on host with 1 Core2 Quad CPU and 16 GB of RAM. The installation is fresh and there are no VMs in inventory yet.
The problem: out of these 16 GB, only about 7.2 are actually allocated for virtual machines. When I open the Memory section in the Configuration tab of VI client, I see the following:
Total: | 16279.1 MB
|
System: | --- |
Virtual Machines:
| 7286.0 |
If I go to Configuration --> System Resource Allocation --> Advanced --> host, I see that 7286 MB is exactly the quantity reserved for "host" (to VMs, as I understand). This reservation cannot be modified.
The Summary tab shows "Memory usage" equal to 8989.0 MB (out of 16279.05 MB) - contrary to the fact that nothing runs on the ESXi hostm except itself. In the same way, Performance also shows that 9205048 KB are Consumed by the host.
Why does it bother me - because I would like to use as much RAM as possible for VMs memory reservations. Currently, if I try to define a new Resource Pool, I see that maximal RAM that can be reserved is 5939 MB - and that's all!
What can be reason for this? Does ESXi host really allocates all this RAM for itself, or it just does not utilize it?
I would very appreciate any help.
Thanks in advance,
Vladimir.
