ESXi System Resource Reservations
Posted on 2011-05-02
As my first step away from ESX toward the new and exciting world of ESXi I apparenlty missed somethign somewhere.
It was my undestanding that in ESXi there was no reason for Resource reservations. Furethermore when I look a the default configuration I see 0MB reserved.
However, I have a 3 host cluster with with 50 VM's. When I tried to remediate my servers with the 2 patches released on 4/28, I received the following error:
Migration to host <<unknown>> failed with error Out of memory (195887124).
vMotion migration [220855820:1304344934423656] generator failed to allocate publicData memory
Can someone please point me in the right direction here. My initial reaction was that I needed to increase the ESX memory reservation, but I wanted to bounce the idea off of some experts....
And FYI, when I run all of my VM's on 2 hosts they both sit at 60% memory Usage.
