HI CArlos
> You should take a look at the default oned.conf file [1] and look for any
other changes that might break things then.
The differences between the default and oned.conf used in my installation
are as follows:
DATASTORE_MAD = [
executable = "one_datastore",
arguments = "-t 15 -d fs,vmware,vmfs,iscsi,lvm,ceph"
]
MANAGER_TIMER = 10
Do These differences imply in an error?
The only reference to virtualization on the host BIOS is: intel
virtualization tech [enabled]
I think my problem is due the fact that the CentOS server is installed on a
XCP VM . According to the tutorial [1], the information of the CPU must
contain the 'vmx'parameter , which does not happen on centOS. The XCP
hypervisor CPU contains this parameter.
I will consult the libvit mailing list to try to find a solution.
thanks a lot
André
