<DIV>Yes, AFAIK, resize is only possible on XenSever.</DIV>

<DIV>> Hi,</DIV>
<DIV>></DIV>
<DIV>> instance's resize is something you can do on xenserver only.</DIV>
<DIV>> I did test it succesfully on XenServer 5.6.</DIV>
<DIV>> Live migration and block migration are KVM features:</DIV>
<DIV>> http://wiki.openstack.org/ReleaseNotes/Diablo#Feature_Disparity_KVM_vs_XenServer</DIV>
<DIV>></DIV>
<DIV>> To properly setup XenServer you should follow this page:</DIV>
<DIV>> http://wiki.openstack.org/XenServerDevelopment</DIV>
<DIV>></DIV>
<DIV>></DIV>
<DIV>> Hope it helps</DIV>
