[Xen-users] Ubuntu Server 11.04 comes with a ParaVirtOPS dom0 enabled kernel out-of-the-box!
Guys, Check this out! lsb_radministrativo@natty01:~$ *lsb_release -ra* No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu natty (development branch) Release: 11.04 Codename: natty administrativo@natty01:~$ *grep -i xen /boot/config-2.6.37-7-generic-pae * CONFIG_XEN=y CONFIG_XEN_DOM0=y CONFIG_XEN_PRIVILEGED_GUEST=y CONFIG_XEN_PVHVM=y CONFIG_XEN_MAX_DOMAIN_MEMORY=128 CONFIG_XEN_SAVE_RESTORE=y # CONFIG_XEN_DEBUG_FS is not set CONFIG_PCI_XEN=y CONFIG_XEN_PCIDEV_FRONTEND=m CONFIG_XEN_BLKDEV_FRONTEND=m CONFIG_NETXEN_NIC=m CONFIG_XEN_NETDEV_FRONTEND=m CONFIG_XEN_KBDDEV_FRONTEND=m CONFIG_HVC_XEN=y CONFIG_XEN_FBDEV_FRONTEND=m # Xen driver support CONFIG_XEN_BALLOON=y CONFIG_XEN_SCRUB_PAGES=y CONFIG_XEN_DEV_EVTCHN=m CONFIG_XENFS=m CONFIG_XEN_COMPAT_XENFS=y CONFIG_XEN_SYS_HYPERVISOR=y CONFIG_XEN_PLATFORM_PCI=m CONFIG_SWIOTLB_XEN=y I know that the Ubuntu 11.04 will be shipped with the Linux 2.6.38, wich probably will come with the needed backend drivers! Now I''m working to test the Xen 4.0.1 compiled from sources but, used with the default Ubuntu Kernel! I''ll post the results here! BTW, I''m working on a new Xen 4 Ubuntu Packages, that will include all Xen stuff, like blktap2, netchannel2, HVM and stubdomains, etc... Because the Ubuntu does not provide the latest Xen version...

I don''t think one more brain would hurt. And by the way, we have already xen-qemu-dm (eg: HVM support, which I maintain) ready, and Waldi (eg: Bastian Blank) did quite a huge work on packaging Xen for Debian. It would be silly to do the work twice when we are in fact lacking resources.

KVM is in the kernel. The Xenlinux patches were proving too administratively difficult to apply and support, from what I understand. And since it''s going into the kernel, all distros will have the option to enable xen pv_ops in their kernels. Whether they support it with frontend management tools is another issue.... _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

But its a good preview of what to expect going on as Dom0 support just becomes an expected part of the base kernel.
