I am confused with a problem: I have a blade with 64 physical CPUs and 64G physical RAM, and defined only one VM with 1 CPU and 40G RAM. For the first time I started the VM, it just took 3s, But for the second starting it took 30s. After studied it by printing log, I have located a place in the hypervisor where cost too much time, occupied 98% of the whole starting time. xen/common/page_alloc.c

...bnormal user program calls create_periodic_time to set the rate again and again, how do we avoid the influence upon our time in vm? how do we compensate the elapsed time at the switching point? especially when the switch is so frequent. can some big figures give me some advices on this? thanks! tupeng212 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
