Start a new virtual machine failed by virtual flash read cache?

[joestho]

- I got this error when trying start a new virtual machine in a cluster:

     "the available virtual flash resource ('0' bytes) is not sufficient for the requested operation ('10737418240' byte"

- I have started 20 virtual machines with flash read cache normally a few day ago and free 92GB capacity for virtual flash read cache per host. Now I create a new virtual machine and can not start by above error.

- I had google search for this error but don't have any answer.

Help me,pls

As a test, power off another VM and try to power on this VM, the cache will be removed when virtual machine is powered off.

Then if the VM power on successfully, check your swap configuration.
