[one-users] Opennebula and Xen 4.1.0

[Ruben S. Montero]

Hi,

It seems that it is complaining about not having sched-cred, that it is used
to implement the capacity distribution set in OpenNebula (a VM with CPU=0.5,
will be assigned a proportional amount of credits so it gets half of the
credits of a VM with CPU=1.0)

Just edit $ONE_LOCATION/var/lib/remotes/vmm/xen/deploy.sh and comment the
line that refers to sched-cred. Use onehost sync (and wait for a monitoring
action on the hosts....)


Cheers

Ruben
