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

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

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

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

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

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 \

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

/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

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

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

(xm sched-credit) Error: cap is out of range
I have xen 3.2 running on an 8 core server. I tried to set
xm sched-credit -d mydomain --weight=1024 --cap=800 and got:
Error: cap is out of range.
I thought 8 cores are 800% ?! So, do I have du use 100 (for 100%)
instead of 800 (for 100%)?
And what about vcpus in my domu config? Must I set vcpus when cpu_weight
is set? If yes (e.g. vcpus = 2) does this restrict cpu_weight only to 2
cpus??

[PATCH]configuration files(sched-credit)
Currently with the credit scheduler, cpu_weight cannot be assigned to guest
domains at boot time.(it can be set with xm sched-weight after booting)
This patch allows CPU weight, and CAP to be set by the Xen configuration
files.
Specification:
The following can be added to the Xen configuration files.

SSH Console issues with Ubuntu
Hi,
When I login to a Ubuntu 10.04 virtual machine instance running in
Xen through SSH, the console''s lines are clipped at the middle section of
my 15.6" screen. I''ll be glad if somebody can suggest a fix. This is turning
out to be very annoying.
Thanks,

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

CPU cap
Hi Everyone,
What''s the parameter in the DomU config file to cap the CPU on the
domain? I tried using "cap = 20". While the VM booted ok, doing a "xm
sched-credit -d </domain/>" showed the cap as being 0
Any ideas?
Thanks
