The problem is now solved
It seems to be caused by a bug on the file: "src/vmm/XenDriver.cc", line
134.
This line contents:
file << "vcpu = '" << vcpu << "'" << endl;
And it should be:
file << "vcpus = '" << vcpu << "'" << endl;
In this way, the launched VM has the specified numbers of cores...

Hi:
we are attempt to up a VM with 4 cores in a physical host with 8 cores
(2 processors of 4 cores each).
We are using OpenNebula 1.4 with xen (CENTOS 5.5 as OS)
The OpenNebula template machine include the variables:
CPU = 4
VCPU = 4
MEMORY = 8192
But the file "deployment.0" generated only have these line relevant to
the CPU stuff:
#O CPU_CREDITS = 1024
memory = '8192'
vcpu = '4'
And the problem is that the generated VM have only a core....
Where is the missing "cpu=4" parameter in the "deployment.0" file???
How can we do in order to select the numbers of cores that a VM can
see???
Regards.
