/dev/hvc0: No such file or directory
Hi Everyone,
In the guest image I download from stacklet, a Ubuntu 10.04 x86_64 DomU,
in /var/log/auth.log, I see:
/dev/hvc0: No such file or directory
listed a lot of times. I''m not experiencing any problems, however it
makes looking through logs for auditing purposes a bit annoying.
Any ideas what this is? I think it has something to do with the

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

high "init" load on ubuntu domu with centos dom0
I have an odd problem. I am running an ubuntu 10.04 domu that I got from
stacklet on my centos 5.5/xen4.0.1 dom0. The problem is that even
sitting idle the domu has a 1.05 load with init taking up 99% of that. I
have searched around but have not found what is causing the issue. I
thought I remembered this being mentioned on the list before but could
not find it either.
My domu.cfg is as

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

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 \
--noreboot \

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

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

My future plan
My future plan currently looks like this for my VPS hosting solution, so any feedback would be appreciated:
Each Node:
Dell R210 Intel X3430 Quad Core 8GB RAM
Intel PT 1Gbps Server Dual Port NIC using linux "bonding"
Small pair of HDDs for OS (Probably in RAID1)
Each node will run about 10 - 15 customer guests
Storage Server:
Some Intel Quad Core Chip
2GB RAM (Maybe more?)

Convert HVM to PV
Hi Everyone,
To convert an HVM install to PV, is it just as simple as creating a new config file, and use the "kernel" and "initrd" parameters to boot from a XEN kernel stored in the Dom0, and use the (ex) HVM''s disk image in the "disk" parameter?
Or is there something else I am missing?
Thanks

Dell OpenManage
Hi Everyone,
I have a Xen host (Xen 3.4.2) which is running CentOS 5.5 Dom0. I wish to install Dell OpenManage to get a nice web interface with hardware status.
Do I need to do anything special to get this working on a Xen host? Or does it work out of the box? The reason why I''m asking, instead of trying, is that my server is currently on its way to a colo, and I won''t have

Creating a paravirtualized guest with Xen 3.4.1 and Centos 5.3 (64bit)
Hi,
I have a set of 32bit HVM images running fine under Xen 3.2.1 and Xen 3.4.1. Due to performance issues with the fully virtualized setup, I would like to migrate one of those images to a paravirtualized image to compare the network performance. As I do not have a Xen-aware kernel for that VM, I thought the best would be to provide one from outside.
Sounds like an easy task, doesn''t

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 \

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

scalability
Hi Folks,
How scalable is dovecot. Do you think a machine with a dual core 2.8Ghz
processor and 2GB of RAM would do a business with 600 users? This server
will have a 100Mbps link to the net, however it will be access by the
business using a couple of ADSL lines (Roughly 7Mbps each).
This machine will also be running Postfix
Your help is appreciated
Cheers

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

Xen on ALIX 2D3
Has anybody tried running Xen on an ALIX 2D3 board?
http://www.pcengines.ch/alix2d3.htm
If not, has anybody ran Xen on a seriously underpowered PC? The reason
why I love these boards so much is that they run at 5W!
Of course, I would only run Xen on these for testing purposes. It would
just be nice to have a very low powered system that I can just "blow
away" VMs when I

trouble launching vm''s
Hello,
I must be missing something very very basic. Because I am having
trouble launching some vm''s that I recently built whereas I don''t have
any problem at all launching some older images I made in very much the
same way!
First there is vm01 which works just fine:

Using config file "./vm01".
