How memory has been allocated for ESXi server?

http://serverfault.com – We are server with 48 GB RAM.( We have installed ESXi 4.1 ) For each VM we are allocating 4GB of memory. Since the server is having 13 VM, My manager thinks that i am doing wrong thing. I am going to explain them that it will actually manage by itself. But they asked me how much memory did you allocate for ESXi server? I did not allocate any [I am not even heard of an option about allocating memory for ESXi server]. How main memory has been allocated for ESXi server? How it distirbutes RAM among VM without any issue? (HowTos)

Stories similar to How memory has been allocated for ESXi server?

Yesterday, I had a ESXi server working. Total memory required by the deployed virtual machines is higher than the physical RAM. The disk also has a few Gigabytes of free capacity.

Today my server stopped normal operation!

When running VMs on an ESXi host, you can overcommit the memory.

Example: host == 20GB physical RAM

The amount of RAM allocated to each VM is

VM1 == 10gb VM2 == 10gb VM3 == 10gb VM4 == 10gb

The result is even though there is only 20GB of ram available, We have actually allocated 40GB of it.

There is no problem with this if each machine uses and average of 5GB of "active" memory (inactive me

I am having a problem with on of our ESXi servers and hoping someone can help us resolve it. I just installed ESXi on a server with 2 2TB drives that are in a RAID 1 configuration using an Adaptec 2405 RAID Controller.

I am trying to setup ESXi in a server and I am a bit lost.

I have an 8-core system (two quad-core Xeon processors) with 8 GB of memory running VMware ESXi 5.

I have 3 VMs currently running: 1 Debian VM using 1 vCPU, 1 WinXP VM using 2 vCPUs and my SQL Server VM.

Does anybody here tried installing ESXi 5.0 on a HP MicroServer N36L? I need your expert advice if the said server can run ESXi seamlessly. I have seen some video showing they have installed esxi on that server but not sure if it's real. Thank you all in advance.

Copy VM from ESXi 5 to ESXi 4? 41 weeks 11 hours ago

Searched Serverfault (and Google) for this, haven't been able to find an answer... We copied a VM (folder and files) from an ESXi 5.0 server (5.0.0-623860) to an ESXi 4.0 server (4.0.0-261974).

Often our team members are coming to me with a compliant that their VMs are slow.

Our team members suggested to shutdown some of the VMs temporarily and try to access the VM.

But most cases that would not help.

Assume that i have assigned 4 GB for and 2 CPUs for my VM. So ideally it should not face performance issue.

It seems like this question should be answered easily, but my google-fu may not be up to snuff.

I am a hobbyist ESXi user/ freelance developer/ systems engineer. I don't have my ESXi server on a UPS.

If I am away from home, and my house experiences a power outage, the ESXi server is set to come back on automatically when power is restored. What happens with the guest OS's?
