I mean, disk I/O bandwidth and bandwidth to the disk controller has to be shared, but if only one domain is using it, I'd expect it to be disk bound: disk I/O is expensive in a virtualized environment, but it shouldn't cost *too* much if hte guest domains are not churning the disk.Hi, Can anyone point me to some information about the behaviour of Xen concerning Disk I/O. What happens on my computer is that whenever I activate Xen, the I/O capability of my hard drives is divided by the number of Xen virtual machines. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
