Hi, I am sucesfully running 2.6.30 xenified kernel: Machine DELL Optiplex 960 CPU intel E8400 8GB RAM Debian lenny 5.0 x64 Xen 3.4.1 rc11 + kernel 2.6.30.2 xenified thanks to howto from bderzhavets: http://bderzhavets.wordpress.com/2009/07/07/building-xenified-2-6-30-1-kernel-via-xen-patches-2-6-30-2-tar-bz2/ So far running ok. 1) I am not able to resolve issue while booting xenified

Andy, OSOL 2009.06 been installed in stub domain (hvm domain) at mentioned Dom0 with 2.6.30 xenified kernel via xen-patches-2.6.30-2.tar.bz2 refuse to activate PV drivers. When same Dom0 starts with 2.6.29.4 xenified kernel (xen-patches-2.6.29-6.tar.bz2) kernel OSOL 2009.06 in stub (hvm) domain does activate PV drivers for xdf, xnf . Boris

Hello,   I can say that I have searched the entire ''world wide web'' and still haven''t found ''complete  and clear answers'' to the often asked question of: Given a Xen (release) build (say 3.2.0), which by default tries to get and build and assume Linux kernel-xen 2.6.18 from the mercurial repository, HOW TO override the build and make it work with a

Hello all, I compiled the kernel with the xen patch and I seam to have trouble with some kernel modules, like ATI''s proprietary driver. The system seams considerably slower than before, this might be because of the video drivers, or maybe the RAM alocated to dom0 (512Mb instead of it''s usual 1Gb). When I try to run xend, it dies with a SIG 15. I attached the log file. Anyone

I have installed Ubuntu Intrepid Server on bare metal and successfully ran:- # apt-get install ubuntu-xen-server.     It installed several packages on system . Now i can see files /boot/xen-3.3.gz, /etc/init.d/xend, /etc/init.d/xendomains, but no xenified kernel gets in. Attempt  to use vmlinuz-2.6.27-7-server, obviously , fails with system panic.    I do remember recompiling  procedure for Xen

  Tne answer is NO. Any vanilla kernel (> 2.6.27) itself allows only to enable PV Guest (paravirtual) mode, but not Xen Dom0 Support. Mainline Linux doesn''t  contain Xen Dom0 Support merged. You have to work on it on your own.   I''ve sent you two links in the very first message. View second one - patching 2.6.30.1 via Andrew''s Lyon rebase patch set :-  

First let me say that I'm not a sysadmin, but am simply wearing that hat this week so please excuse my ignorance. I need to temporarily move some virtual servers from a CentOS-KVM platform to a CentOS-XEN platform while I do some upgrades to the CentOS box. I've created a local LV, and used DD and SCP to transfer the block device from the VKM machine to the XEN machine. For quite a

Odd question I know. I am looking for source for as recent a kernel as possible running the old style xenlinux/xenified kernel (i.e. capable of running the xen3.3.x hypervisor). Any ideas where I can get this - preferably in git form? I think Stefano Stabellini had something that worked up to 2.6.36 (from memory). And yes, we would all prefer all our customers moved to xen4 but this is difficult

Hi Folks, I need some large chunk of physical memory, so I allocate it early using alloc_bootmem_low_pages and use it later (akin to bigphysarea patch). The trouble I am having is the following. Suppose the virtual address for the memory area is 0xc14d6000. After xen_create_contiguous_region call, I do a virt_to_bus and the bus address comes out to be 0x18000000. So far so good. However,

Hi there, I am starting a new thread to try and solve a problem I am having will slow network throughput to the XEN host (not to a domU). I have confirmed my problem occurs with PVOPS ''xen/master'' kernel as well using http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.31.6-pvops-dom0-xen-master-x86_64 as the .config. It also occurs with a forward ported xenified kernel

Jup, 64 Bit Kernel build is done now and works, but 32 Bit kernel config is different, as I use 64 Bit in Dom0 and DomU, 32 Bit only in DomU incl. DomU with DVB etc. XEN options are the same, it''s only the selection of drivers... Andrew, any idea? Boris, do you know a safe way to create a 64 Bit config out of a 32 Bit one? Sorry, I am not so used to kernel building... BR, Carsten.

Hi Daniel, i''ve tested your kernel with slight modifications to your .config (-> domU only) on 64bit 3.2.1 and 3.3 as guest kernel. Compared to the classic 2.6.18.8 the guests are consuming about 25% more CPU, network IO increased by about 15%, disk IO also. Memory footprint is about 10% less. Maybe there are better caching strategies built into this 2.6.29. I''d like to try

Hello Everyone, We have noticed that one of our servers xen Dom0 is restarting idiopathically. Atleast, we are not able to analyze the cause. I have checked the logs but couldn''t find anything relating to it. Are there any tools such as kdump (which doesn''t seem to work on xenified kernels) for catching the kernel crash snapshot. Regards, Sree Harsha Totakura Member, Open

Hey guys, I''m trying to get a gentoo dom0 running on some new Nehalem boxes. Our dozen or so existing servers run a xenified 2.6.21, but we can''t get the new Intel network chipset working with it. So, I''m giving a pv_ops dom0 from xen-tip/master a go, and Xen 3.4.1 to go with it. rebase/master is a bit too bleeding edge for me. So far, it''s working great.

Greetings list, I've compiled and installed dahdi countless times on standalone machines, but recently I've been trying to compile Dahdi in a Xen DomU without much success. The errors I'm seeing are as follows: /var/tmp/portage/net-misc/dahdi-2.3.0.1/work/dahdi-linux-2.3.0.1/drivers/dahdi/zaphfc/base.c:1689: error: 'modes' undeclared (first use in this function)

Hello list, when using Xen on our Bladecenter with the advanced management module everything works fine, but as soon as I switch the KVM to another blade and then switch back to xen machine, vga output is unavailable (due to wrong resolution or hz frequency? But it works if I don''t switch away). The machine itself works, only vga output is gone after switching kvm away from the box.
