This patch allows vcpus_params cpu_weight and cpu_cap to be saved and restored. Most the code to support this already existed, but the save path needed to be updated to explicitly save these params, and the restore path needed to be updated to resend the params down to the kernel. diff --git a/tools/python/xen/xend/XendConfig.py b/tools/python/xen/xend/XendConfig.py --- a/tools/python/xen/xend/XendConfig.py +++ b/tools/python/xen/xend/XendConfig.py @@ -1088,6 +1088,10 @@ if self.has_key(legacy) and self[legacy] not in (None, []): sxpr.append([legacy, self[legacy]]) + if self.has_key('vcpus_params'): + sxpr.append(['cpu_weight', int(self['vcpus_params'].get('weight', 256))]) + sxpr.append(['cpu_cap', int(self['vcpus_params'].get('cap', 0))]) + if self.has_key('security_label'): sxpr.append(['security_label', self['security_label']]) diff --git a/tools/python/xen/xend/XendDomainInfo.py b/tools/python/xen/xend/XendDomainInfo.py --- a/tools/python/xen/xend/XendDomainInfo.py +++ b/tools/python/xen/xend/XendDomainInfo.py @@ -2448,6 +2448,8 @@ raise VmError("Cpu cap out of range, valid range is from 0 to %s for specified number of vcpus" % (self.getVCpuCount() * 100)) + xc.sched_credit_domain_set(self.domid, weight, cap) + # Test whether the devices can be assigned with VT-d self.info.update_platform_pci() pci = self.info["platform"].get("pci") _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
