High Number of VMs
Hi, I''m curious about how you guys deal with big virtualization
installations. To this date we only dealt with a small number of VM''s
(~10)on not too big hardware (2xquad xeons+16GB ram). As I''m the
"storage guy" I find it quite convenient to present to the dom0s one
LUN per VM that makes live migration possible but without the cluster
file system or cLVM

lenny amd64 and xen.
I''ve installed debian lenny amd64, it is frozen now.
I''ve install kernel for xen support but it doesn''t start.
It says "you need to load kernel first" but I''ve installed all the packages
concerning xen, also packages related to the kernel.
Perhaps lenny doesn''t support xen anymore?
Any solution?

1/2 OFF-TOPIC: How to use CLVM (on top AoE vblades) instead just plain LVM for Xen based VMs on Debian 5.0?
Guys,
I have setup my hard disc with 3 partitions:
1- 256MB on /boot;
2- 2GB on / for my dom0 (Debian 5.0) (eth0 default bridge for guests LAN);
3- 498GB exported with vblade-persist to my network (eth1 for the AoE
protocol).
On dom0 hypervisor01:

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.

Samba4 stability: Just because I'm curious
Hi people:
I know that Samba4 isn't ready for production yet, i understand that
is in alpha phase. But I'd like to know what "isn't ready for
production" means? What minimal features are stable and what aren't?
Does this mean that the basic funcionality could just make Samba4
hang?
I would appreciate some comments about the features or reasons that
makes Samba4 unstable

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:

LVM over Xen + Network
Hi,
We are planning to have LVM being used over a network of 3 h/w machines(500
GB Disk each)
Each hardware machine will have 2-3 domUs.
Can we store these domUs as a Logical Volumes stored across Network of these
3 machines?
Can one DomU exceed the 500 GB (physical drive size) and store say 1 TB of
data across the networked Physical Volumes?
Has anyone done this before?
Thanks and regards,

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?)

Can SAMBA work with 2008 R2 Read Only Domain controller
Hello,
?
We are planing to utilize Microsoft 2008 R2 Read Only Domain controller, and deploy RODC's in branches.
?
If I would like to have SAMBA servers in those branches, will I be able to add them to the domain (using "net ads join") and work with them, when using the RODC's as domain controllers configured in my smb.conf & krb5.conf?
?
I have looked around and did not

How many guests
Hi Everyone,
I have a Dell R210 server which has a Xeon X3430 Quad Core CPU (2.4Ghz x
4) with 8GB of RAM. I intend to use the H200 controller in a RAID1 setup
How many VMs do you think I''d be able to run on this machine? Is 20
pushing it?
I''d say most (if not all) guests would be in PV mode.
Thanks

Opinion on best way to use network storage
I need the community''s opinion on the best way to use my storage SAN to host
xen images. The SAN itself is running iSCSI and NFS. My goal is to keep
all my xen images on the SAN device, and to be able to easily move images
from one host to another as needed while minimizing storage requirements and
maximizing performance.
What I see are my options:
1) Export a directory through NFS.

XEN and clustering?
Hi.
I''m using Xen on RHEL cluster, and I have strange problems. I gave raw
volumes from storage to Xen virtual machines. With windows, I have a
problem that nodes don''t see the volume as same one.... for example:
clusternode1# clusvcadm -d vm:winxp
clusternode1# dd if=/dev/mapper/winxp of=/node1winxp
clusternode2# dd if=/dev/mapper/winxp of=/node2winxp

Xen on two node DRBD cluster with Pacemaker
Hi all,
could somebody point me to what is considered a sound way to offer Xen guests
on a two node DRBD cluster in combination with Pacemaker? I prefer block
devices over images for the DomU''s. I understand that for live migration DRBD
8.3 is needed, but I''m not sure as to what kind of resource
agents/technologies are advised (LVM,cLVM, ...) and what kind of DRBD config

lvm over nbd?
I have a system with a large LVM VG partition.
I was wondering if there is a way i could share the partition
using nbd and have the nbd-client have access the LVM
as if it was local.
SYSTEM A: /dev/sda3 is a LVM partition and is assigned to
VG volgroup1. I want to share /dev/sda3 via nbd-server
SYSTEM B: receives A''s /dev/sda3 as /dev/nbd0. I want to
access it as VG volgroup1.

best practices in using shared storage for XEN Virtual Machines and auto-failover?
Hi all,
Can anyone pleas tell me what would be best practice to use shared
storage with virtual machines, especially when it involved high
availability / automated failover between 2 XEN servers?
i.e. if I setup 2x identical XEN servers, each with say 16GB RAM, 4x
1GB NIC''s, etc. Then I need the xen domU''s to auto failover between
the 2 servers if either goes down (hardware
