Hi All, I just tried a new installation of Ubuntu 10.04 (64bit) + Xen and am having some trouble starting XEN. I am using the latest mercurial checkout (4.0.2-rc2) and the only change I made was to Config.mk to enable building the OCAML version of xenstored. " CONFIG_OCAML_XENSTORED ?= y". I am using the same kernel I built earlier for a similar Ubuntu 10.04-64bit / Xen 4.0.0

Hi everyone, I''m trying to start up domU on xen for ARM (Cortex-A15 Fast models). I follow the instructions to build xen-tools with this link: http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/CrossCompiling. But there seems to be something wrong when I start up domU. First, I get errors in create domU with xl: root@(none):/home/xiaogw# xl create domU-config xc: error:

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths
