Hi, I have the following problem to solve. Let's say guest domain 1(guest1)
is allocated with 30% of the physical CPU by running the command " xm
sched-credit -d guest1 -c 30). Then at some point of the application
processing hosted in guest1, I need to increase its CPU share from 30% to
60%. How can I do this? First, guest1 should notify Xen hypervisor that it
needs a CPU share change. Then Xen hypervisor makes the change
automatically(not running the command manually).
 
I am new to Xen. Any help would be greatly appreciated!
