Hi, I am wondering if it is normal that guest created on partition is slower thatn guest created on a file(created using dd). I have created two guest using virt-install.One is on my /dev/hda5 (guest name is partition) while the other on /storage/vmdisk.img (dd if=/dev/zero of=/storage/vmdisk.img bs=1024k count=1024 )guest name is file using hdparm -tT in these two guests shows the throughput of partition is 3-5Mb/s,while the number on guest file is around 30. This discrepancy is quite huge. Is this normal? thanks _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
