Subject:Â[Xen-users] Compiling Xen from source on a machine without Internet access
Hi,
I am trying to compile Xen 4.0 on a machine without access to the Internet. However it does not work directly since the make process does a "hg" and gets some files from an svn. Is there a way I can compile Xen from source on a machine which cannot access the Internet? I am looking for something other the obvious answer of "compile it on another Internet-connected machine and copy the result to that machine which is not connected to the Internet" (both these machines can talk to each other).
Thanks,
Virajith

ÂYou can make your kernel externally (fetch the source per git from the pv_ops repository or xen) and just create the xen tools with make xen and make tools, then you can install it per ./install.sh in the xen src dir, as far as I remember. Check the xen-wiki for futher details.

Subject:Â[Xen-users] CentOS 5.5, XEN-4.0 (gitco), Kernel 2.6.34-xenified and Fedora11-PV
Hello,
im struggling with getting a Fedora 11 Domu up and running.
My Host is a HP DL380 g6 with CentOS 5.5 and XEN 4 from gitco installed.
The System runs several Linux-PV-DomUs like Debian Lenny, Ubuntu Lucid
and CentOS-55 without any problems.
But if i try to get stock F11 up and running.
Using Virt-install, xm create with KS-Install and Converting a working
HVM-Install did not suceed. The DomU is making IO, comsumes CPU-Time,
but Console and Network are not reachable/working?!
XENinified 2.6.34 uses xvc0 as console while pvops-enabled Kernels like
the Stock (2.6.30.11) Fedora-Kernel use hvc0.
It triple-checked the existence of /dev/hvc0, inittab, securetty but
still no Console available
Tried following Kernel-Params:
extra = 'console=hvc0 earlyprintk=xen'
extra = 'console=hvc0 xencons=tty earlyprintk=xen'
extra = 'console=hvc0 xencons=hvc0 earlyprintk=xen'
extra = 'console=hvc0 xencons=xvc0 earlyprintk=xen'
but still no Luck :-(
Has Somebody a running stock-F11-PV-DomU up and running?
Any Ideas?!
tia,
thomas
PS: my pygrub does not work with timeout=0, maybe pygrub is broken?

As far as I know, Xen hypervisor needs direct access to the real
hardware, so you won't be able to run it inside a virtual machine.

Subject:Â[Xen-users] Installation of Windows 2008 failure in hvm mode
Dear all,
Â
I have installed xen3.4.3 in CentOS5.5 and successful to install CentOS guest OS in para-virtualized mode.
When I use virt-manager and virt-install to install Windows 2008 or Windows 7 under X-Window, the VM in fully-virtualized mode can startup and go into the Installation manual. However, the Windows installation can not find the hard disk that I have assigned during installation. I have typed xm list -l "domain" and found that device have attached to the domain. I also checked the device is attached to the VM under virt-manager.
Â
Any area that I need to check?
Any suggestions?

Yes, I'm using a lot of of freebsd 8.X as domU. In configs I have something like this

Subject:Â[Xen-users] Hi: Newbie intro.
Hi,
I'm grass-green new to Xen. ÂThe only virtualization I've used is VMware
(most recently server) on Linux, Windows and Mac, and Parallels on Mac.
I've used VMware for years as a testing mechanism. ÂI'm not a VMware
expert, but have used it in all the ways I intend to use Xen.
I've been reading through the Xen documentation and have some questions
that don't seem to be clear. ÂI'm not afraid of the documentation. ÂI
haven't waded through it all, but I have not yet found the answers to
some burning questions and can't concentrate on the topic at hand
because of it. ÂSome things just seem to be missing, and I don't know if
it's because I just haven't read that far or if that entire issue is
handled by Dom0. ÂIf something I'm asking about is best described by the
docs, I would love to see a link to that section rather than make you
guys type in a description.
First, my hardware:
I have an Intel i7 920 on an Asus P6T with 12G RAM. ÂThe processor
supports VT-x but not the vpro version. ÂI'm still not clear on the
differences between these.
The drives are SATA, 4xWD750gx10000rpm (WD7500AADS) configured as Linux
kernel-based RAID with LVM2 on top. ÂMostly RAID 1 in 2 volume groups,
two drives per group. ÂThe /boot drive is 4 drives RAID 1, grub boot
loader. ÂI also have a removable SATA drive with 1.5 Tb as a backup
drive. ÂCurrently all this space is mostly empty, but by the time I get
done that probably won't be the case.
I have an nVidia GT200 video card with dual monitors, if that matters.
I also have some other hardware (mostly sound and video hardware) but
that's not pertinent at this point I think. ÂA full hardware profile is
included at the end of my message in case it's pertinent to one of the
questions.
My intent:
This is my home workstation. ÂI currently run Gentoo on it. ÂI also want
to work from it, and I'm a software developer. ÂHere are the VMs I want:
Â1 Gentoo stable. ÂThis is probably going to be where I live most. ÂIt
will have video and sound and will probably use the most CPU of
everything.
Â2 Gentoo ~arch. ÂThis may be a chroot of stable, or maybe a full
image. ÂThis is primarily for testing and experimentation with
unreleased software.
Â3 Windows 2003 converted from a VMware disk. ÂThis has Microsoft SQL
Server on it, and everything is using legitimate developer licenses.
This is used as a database and as a web browser for testing, and has a
couple other end-user tools on it, but very little human interaction.
Â4 Some random flavor of operating system. ÂI sometimes try out a
distro just to see what's going on.
Â5 Possibly one or two other stand-alone server images, usually a
minimal Linux.
Â6 I may also have Ubuntu on it. ÂFor some reason I'm fixated by this
distro.
Stable and Windows 2003 will probably start at boot. ÂEverything else
will probably be a manual start-as-needed arrangement.
My questions:
1. ÂBoard issues.
http://wiki.xensource.com/xenwiki/VTdHowTo shows a line which causes me
concern:
ASUS P6T Deluxe (Intel X58 chipset) requires (currently non-public) BIOS
update to correct DMAR-table issue
My board is P6T, not deluxe. ÂIt has the X58 chip set, the BIOS is set
to allow VT-d, but I'm not sure if this board has the broken BIOS like
the Deluxe, or if it has a good BIOS, or if it is missing the feature
which requires the fix altogether. ÂCan this board run VT-d in a proper
way? ÂDo I need to get a different board in order to make this work
well?
2. ÂDom0 strategy:
I'm a bit confused as to the entire role of dom0. ÂIs this supposed to
be just a minimal command-line distro for drivers and Xen admin, or is
it a full-blown distro which also has Xen admin? ÂDo I want flexibility
or stability? ÂRolling release or conservative non-rolling release?
Admin-only or do I live here?
3. ÂPartitioning:
I'm currently using RAID per linux-only schemes. ÂDoes Xen have its own
requirements and abilities for that, or is that entirely handled by
Dom0?
Do I assign logical volumes directly to the DomUs with the proper
partitioning scheme or do I store everything on XFS in a big file and
let the DomU partition that file?
Does it make sense still to segment the system out to different
partition types for performance, or what? ÂWhat's the strategy?
Thanks.

Admin-only or do I live here?
Dom0 is to Xen a bit like user root is to Unix style systems. Xen loads first and sits on top of the hardware, but Xen itself doesn't really have any way to interact with it. It loads Dom0 as the first guest OS (and yes, even Dom0 is a virtual machine I believe) - and gives it special privileges, such as being able to communicate with the hypervisor and control it. Dom0 also gets direct access to all hardware by default.
It is customary that Dom0 is a "light" install - just containing what you need to run the machine. It doesn't have to be, you can load up all your GUI shells, user apps etc - but it's custom to keep Dom0 light because of it's privileged role and the fact that if you compromise Dom0 then all the guests are compromised.
So if you have a machine that is your desktop, then it's quite OK to run Xen on it, use Dom0 as your "desktop machine" and fire up some other guests as required. You just have to accept that if you compromise your desktop machine, then the others are compromised too. it would be a good way to get started and experiment - just not good for running production services.
3. ÂPartitioning:
I'm currently using RAID per linux-only schemes. ÂDoes Xen have its own
requirements and abilities for that, or is that entirely handled by
Dom0?
Do I assign logical volumes directly to the DomUs with the proper
partitioning scheme or do I store everything on XFS in a big file and
let the DomU partition that file?
Does it make sense still to segment the system out to different
partition types for performance, or what? ÂWhat's the strategy?
Again, this is largely a matter of personal preference. In terms of performance, then unless you take steps to segregate stuff (eg keeping different bits of data on different drives), then the I/O from all your guests shares the same disk I/O bottlenecks. In some ways it could be said to be worse since you will typically have the virtual disks for different machines spread across the disks and thus ensure lots of head seeks.
Xen does not handle any file systems on it's own, whatever containers you use are transparent to the hypervisor. What type of container is again a matter of preference.
At one extreme, you can build a big filesystem for Dom0, and use file to store the virtual disks for the guests. Personally I use block devices and LVM - I create on logical volume per filesystem in each DomU, and I don't partition them in the DomUs. This has the advantage that each filesystem can be mounted in Dom0 without any hassles (ie you can just "mount /dev/vg0/guest1root /mnt") and have access to the file on the guests disks (but you must shut down the guest first).
If you create a virtual disk and partition it inside the guest then filesystems can still be mounted elsewhere, but there's an extra step or two involved.
One LV per filesystem also makes resizing filesystems a doddle - shutdown guest, shrink filesystem if reducing size, resize LV, expand filesystem. There is talk of it being possible to resize (expand) the LV and trigger some signal to make the increased size visible to a running Dom0, and then live-expand the filesystem.
As mentioned above, many of the same performance issues arise, but with some added complications because you are no longer considering one "machine". If you do have a heavy I/O application, then you may still want to take the usual steps of keeping that data on it's own set of spindles and so on - Xen will let you do that, it really doesn't care what you do.
Dunno about the other questions.

Subject:ÂRe: [Xen-users] Hi: Newbie intro.
Simon,
That helps a lot. ÂMuch of what you said matches what my impression was,
especially about Dom0. ÂI think in that case I will make a minimal
distro for that, and keep it simple. ÂAt least until I decide a DomU
might not be adequate in some way, if ever.
With regards to partitioning, I think then what you're saying is that
Dom0 decides what partitions are visible to the DomU, and whether those
partitions are files on a Dom0 partition or if they're partitions on the
same "layer" so to speak.
So just guessing, I'm thinking that Dom0 would be the only thing that
needs to understand RAID/LVM and the DomUs could get by thinking it was
a plain file system.
Another thing: ÂI have this existing Gentoo, that I'm typing on. ÂIs
there some way to preserve it, or should I just figure on starting over?
Is there some way to wedge the hypervisor under it, in place? ÂIs that a
bad idea even if possible, or is it no big deal?
Thanks a lot, you've really helped.

Not really. That's why I said IF it works.
Reading the documentation, it supposed to work some versions back, but
I never got it to work (similar setup as yours). In the end I simply
use phy:/dev/drbd/by-res/ (which works without having to hack any
script), and setup both nodes to be primary if I need live migration.

In general, all you need to do is install a kernel package with Xen Dom0 support, install Xen, and configure Xen+Compatible kernel as a boot option. You should then have the option of booting :
+ Your existing kernel
+ The new kernel
+ Xen plus the new kernel
Another option, but slightly harder as you need to re-arrange partitions a bit ...
Install a kernel with Xen DomU support, put the whole disk/partitions to one side, build a new boot setup with a fresh Xen+Dom0, boot your existing Gentoo as a DomU. A convenient way of doing this is to install a new disk as the primary disk, and then you just configure the DomU to use the real partitions (rather than LVs).
As long as you don't mess up the disk, you then have the option of putting things back and booting up as you are now. I like options with a safety net ;)

Subject:Â[Xen-users] Clone Xen Guest (LVM)
Hi all,
i would liáe to clone a virtual machine from a Sles 10 SP 2 server to
a Sles 11 server.
My Xen-guest runs on Sles 10 SP2 in a Logical Volume.
If i copy all files on a other lvm on the sles 11 server, it starts
only in the console.
On first tests i got some errors on boot. But after i add the old
kernel it starts normal in the console but not with kde and right
network connection.
What did i do?
I tested it also with a not running VM.
I created a snapshot from the running vm.
I mounted it read only.
I copied all files via rsync on a empty (ext3) lv on the sles 11 server.
I unmount the snapshot and the new lv.
I changed harddisk, MAC-adress, IP-adress and boot-kernel (same as the
old server) on the config and start with xm create vm.
If i start the console on virtual machine Manager it boot the system
normal. I can only log in with a non root user. Then i log in as root
from a user and everything is ok.
I can start YaST and change the network settings and can also change
the /etc/hosts manual.
On the sles 10 server i had a xenbr0 network device. On Sles 11 i have
a eth0 bridge as network device.
If i start YaST i see the old device and old ip. I don't see the new
network device.
If i change the ip-adress i see it on YaST but if i start ifconfig in
the console i only get a loop back 127.0.0.1 network device.
If i install a new Guest in a lv on SLES 11 it works perfect but i
did't find a solution to clone an existing virtual machine.
How can i clone a VM on another server where xen is installed?
Best regards
Benjamin Knoth

Good day.
Just few days ago I was solve this problem with outdates e1000 drivers.
My solution:
1) Download source ISO:
http://www.xen.org/files/XenCloud/Software/0.5/sources/source-1.iso
2) Unpack kernel source (src.rpm) for needed kernel.
3) Copy it to /usr/src/linux to target XCP host
4) remove citrix broken repo and enable centos repos.
5) install gcc, make, binutils, etc.
6) compile kernel sources (modprep usually enough), configuration for
compilation avaible from /proc/config.gz.
6) use ./configure option to specify path (most of scripts will search
