Hi all, I downloaded a pre-compiled Fedora 11 domU image from http://stacklet.com/downloads/images/list/Fedora When I ran the domU (2.6.30) with xen 3.1, 2.6.18 dom0, there was a problem. I can not change the memory configuration of the domU on the fly. I used pygrub to boot the PV guest. In the 2.6.30 guest, I can not find the /proc/xen/balloon driver but in the config file of the kernel, XEN_BALLOON is enabled. Any ideas? Thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

In domU， I tried to compile the newest 2.6.31.6 kernel. It can not boot. I configured the domU to be 4 vcpu, but shortly after creation the domU was shrinked to 1 vcpu and the cpu seemed to be 100% busy from xm top. can not ping or xm console to the domU.
