ionice and blkback
Hi Everyone,
When you want to use ionice to limit the amount of disk a DomU has, due
to have to run ionice on every blkback process?
Incidently, what is the format of the blkback process? I see the
following in ps aux:
blkback.xx.xvda
blkback.xx.xvda1
blkback.xx.xvd
where xx appears to be the domain ID. I''m curious as to the last few
letters mean?
Thanks

ionice
Hi Everyone,
I''m experimenting with ionice, and I have to say at first impressions
I''m very impressed!
Does anyone have any idea how I could script the ionice config? I''m
using phy for my DomUs so everything appears in ps as blkback.<DOMID>.xvda1
The problem is, is that the process id for the blkback process will
change after every DomU restart,

iSCSI and LVM
Hi Everyone,
I am going to get a storage server which will be connected to my Xen hosts via iSCSI/Ethernet. I wish to use LVM for the DomU disks. The storage server will have a RAID10 array, and 2 Xen hosts will connect to this (Each will have a 50% share of the RAID10 array, space wise).
What is the best way to go about this? Should I:
a) Split the RAID10 array into 2 partition on the

RAM security
Hi Everyone,
In Xen, is a DomU able to access data in RAM which a previous DomU has stored in the past, but didn''t "zero" it?
I understand that this is a problem with physical disks (using phy:/), just wondering if the same stands with RAM
Thanks

HVM Network Interfaces
Hi Everyone,
In my HVM guest''s config file, I have given my guest 3 interface. I have
called them fw1, fw2 and fw3. I have joined each interface to a bridge
on the Dom0. This does appear when I do a "brctl show". However, there
are 3 other interfaces also added called tapx.0,tapx.1 and tapx.2 (Where
x is the domain ID for the guest). Furthermore, I am only able to run

qemu disk cache mode
Hi all,
I can''t find any good talk about this subject and would like some insights
and advices on the cache side in xen.
I discovered that a domO power outage can lead to a severe filesystem
corruption of the domUs. The domO is a dual disk dell server with a PERC
controler in writethrough cache mode, the disk cache is disabled, the
scheduler in the domO/domU is NOOP, the domO is holding

Ubuntu 10.04 DomU Xen 4.0
Hi Everyone,
How does one install Ubuntu 10.04 DomU in PV mode when running Xen 4.0? My Dom0 is also running 10.04.
Can I still use the CD?
Thanks

VT-x not found..
Hi Everyone,
I upgraded my CentOS 5.5 to Xen 3.4.2 using this guide:
http://www.syntaxtechnology.com/2010/01/upgrade-xen-3-0-on-centos-5-4-x86_64-to-xen-3-4-2/
Now, using the new kernel that it gave me, the system doesn''t seem to be
able to detect vt-x..
In virt-manager, Local Install Media and Network Boot are greyed out..
Any ideas?
Thanks

as promised description of my XEN HA setup
Hi all,
In threads posted by I believe Jonathan Tripley I promised to post my new XEN
HA setup. Hope it can be of some use to some people.
In this particular case I''m forced to use SLES 10SP3 with XEN 3.2, which
excludes the possibility of using things like cLVM (which I don''t think I need
anyway).
So:
Storage:
I use two HP ML370 G5 machines with DRBD and heartbeat on

Install ubunto domU
Dear *,
I''m more used to work with RedHat like OSes. Still, I did not denied the
request from a user who wants a domU based on ubunto. I usually use
virt-install to do the job, with a script similar to this one:
#!/bin/sh
BASE=SL-4.7-i386-pv \
virt-install --nographics \
--nonsparse \
--paravirt \

Promiscuous mode
Hi Everyone,
In order to prevent DomU from entering promiscuous mode, is it just a matter of adding these 2 rules when the vif is created?
# Accept packets leaving the bridge going to the domU only if
# the destination IP for that packet matches an authorized IPv4
# address for that domU.
iptables -A FORWARD -m physdev --physdev-out vif1.0 \
--destination 216.146.46.43 -j ACCEPT

If a DomU was compramised, could the Dom0 or other DomUs be compramised?
I guess I''m trying to work out how much isolated Xen gives..

Identifying disk resources in dom0
Hello,
For my xen domUs I''m using a mixture of locah physical partitions (with
LVM) and iSCSI disks. For local partitions, I don''t have any problem,
because LVM volumes are always the same. But for iSCSI disks, devices
are assigned in the order they are connected, so I can''t be sured that
device that now is /dev/sdb (for example) will always be /dev/sdb.
So, is there

Xen License
Hi Everyone,
This is going to sound silly but...
I''m just off the phone with a Microsoft SPLA reseller. They sell licenses to run Microsoft software in a hosted environment. I was asking about obtaining Windows licenses to run on my Xen VPS hosting solution.
Maybe there is a big misunderstanding, but I''m faily sure she said that it was illegial for me to rent out Xen

AoE LVM2 DRBD Xen Setup
Hello everybody,
I am in the process of setting up a really cool xen serverfarm. Backend
storage will be an LVMed AoE-device on top of DRBD.
The goal is to have the backend storage completely redundant.
