[one-users] Stuck with LCM_INIT when launchnig a VM !

[Carlos Martín Sánchez]

Hi,

The scheduler log is referring to the CPU and MEMORY requirements.
The available Host CPU is the ACPU column of 'onehost list'. If you do a
'onehost show', you'll see this value corresponds to
TOTAL CPU - USED CPU (ALLOCATED). The available memory follows the same
idea.

Now, here's the catch: the Host CPU is measured as percentages, so 800
means 8 whole cpu cores [1]. but the CPU attribute of the VM definition is
measured as cores, so a new VM with CPU=8 will require a Host with ACPU=800.

In the output of your first email I can see a CPU=100... which means that
the scheduler will only deploy to a Host with 100 free cores (ACPU>=10000)
