LPFC support in Xen ?
Hi,
Afraid I dont have a very new system to try out Xen.. It''s an ia32 PIII
machine with 1GB memory (that''s gud i believe).
When I try to build the initrd image for my xen kernel, i get error
messages complaining about missing modules, so am trying to compile them on
my own.
Could find support for the remaining three, but am left with lpfcdd.ko.
Couldnt find an appropriate

migration considerations
Hi,
I've got a 3ware 9550SX-4LP on a dual xeon 3.6GHz machine (no HVM
possible). 4 SATA-HDs in RAID 5 installed.
xen 3.0.3 with centos-4.4 as xen0. centos-4.4 is also installed on the
numerous xenUs. The xenUs are installed in LVs which are formatted as xfs.
Now I'd like to move over to centos 5.0
This is what I thought to be good as an upgrade procedure:
1) install a xen0 to a

xen, lvm, drbd, bad kernel messages
Regardless of the filesystem (i''ve used reiserfs, xfs, ext3),
whenever I mount a fresh DRBD partition I get some nasty kernel
messages.
This is under Debian Sarge, Xen kernel 2.6.11.12-xen0 (dom0) using
DRBD v0.7.11 (pulled from Debian "testing").
This is what I did to create the partition.
On both nodes I created a new LVM storage device and started DRBD:

Unable to compile drivers...
Hi,
I have installed Xen from the binaries (2.3.4 in "Users'' manual") and I

xen failover
Hi,
I''ve got a question regarding failover.
I''ve set up Xen and DRBD with the versions packaged for CentOS 5.4. Live migration of the domU''s is working between the two xen nodes quite happliy.
Each domU has two LVM LVs associated with it, partitioned as swp and root. DRBD is configured to just sync the LV containing the root partition, not swp.

simple load balancing/failover for OWA
We are building an exchange cluster with two front end Outlook Web
Access servers. We would like to at least have some sort of failover,
and prefereably load balancing for them.
The MS recommended way is to use NLB, but for various reasons that's not
working with our set up.
We are looking to set up a single linux server and use something like

Not able to get eth0 up on domU.
I am using ttylinux-xen file system image a a loopback device for the
domain. I am mostly using the default configuration. I am not able to
get networking on the domU. Are kernel "vmlinuz-2.6-xenU" as well as
"2.6.11.12-xen0" both compiled w/o loadable module support? I guess it
fails when it tries to initialize the iptables on the domU when it tries
to do "modprobe".

All domU are in LVM partitions on dom0.
Each domU have 1 /, 1 swap and 1 /home in reiserfs.
I must migrate all domU to another server, but how can a migrate all the
data and all processes without errors ?
I can stop each domU, it''s not a problem ...
Where can i find docs about migrating a domU to another dom0 ?

How to manage images/partitions for xen DomUs?
Hello,
I am trying to figure out the best way, how to configure a small cluster
with xen and High Availability (Heartbeat). I have two servers and a few
virtual machines. What I need is to ensure, that images or partitions of
the machines will be mirrored between the two nodes (maybe with drbd?).
But that is not all - I also need to enlarge the disks (because of
growing databases) of virtual

Very slow domU network performance
I set up a domU as a backup server, but it has very, very poor

iperf client and the right column is the iperf server):
