Subject: [Xen-users] Disable "Steal Time" in domu?
I was looking at an issue with steal time affecting several instances. Is it
possible to pass a kernel parameter on a Linux vm so that the xen host
cannot "steal time" from it? I would like to isolate some vms from being
part of the pool where resources can be borrowed, or reduce the aggression.
all the best,

If you dedicate whole physical cpu to that VM vcpu on the hypervisor level
(vcpu-pin), there should be no "Steal Time".
Or might try tuning weights&caps in CreditScheduler.
