Subject Oversubscription xenservers
Date Mon, 23 Mar 2015 10:18:21 GMT

I'm Working on a large cloudstack4.4 platforme with multiple Xenservers
6.2. I'm working with an overprovisionning ratio of 1.5 and a dom0=4Go.

When inspecting the cloudstack-management log file while a start a VM
deploiement i' get the error mentionned in the end  wich i need to restart
my server to fix it and the VM is started on another server.

Can any one tell me what should i do to fix this issue.

My log output :
