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,

I/O size distribution?
Hello I have read that under Solaris one can use DTrace to get I/O request size distribution on a global scale (also on a per process/pid basis). See for example http://prefetch.net/articles/observeiodtk.html Can anyone?recommend?an alternative to get similar information under CentOS? I looked into dtrace for linux but it seems still work in progress, even putting aside CDDL issues ...

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

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.

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

Constant disk activity
Hi there, I have an old server (home use now), and i just did a fresh install of 5.8 on it. But the disk is constantly noisy. When running iotop, there is nothing blaring out at me.

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

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

pfSense HVM
Hi Everyone, Does anybody have any experience using pfSense on Xen? I would most probably have to use HVM... My idea would be to use PCI-Passthrough to the pfsense DomU, and only make the Dom0 accessable via the pfsense firewall Thanks Jonathan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

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

logging on client side on NT
Hi, I would like to log whatever happens with rsync on client side when it runs with Cygwin on NT4. First, I just did a redirect of the screen output to a log-file: rsync -rtv --delete --modify-window=2 --stats /cygdrive/g/users/bco/test/ bee2bs01::d/test/ >>c:\rsync\log\%FDATE%.log The problem with this method is that it does not redirect whatever Rsync reports as errors; because they

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

live migration in between different CPU families
Hi, referring to thread: http://www.gossamer-threads.com/lists/xen/users/177385#177385. I have the same thing going on: hypervisors with E5620 Xeon CPUs and hypervisors with E5410 CPUs. Live migrations go wrong when domU''s are not created on the latter and move from the E5410 servers to more recent ones. The rationale being that these CPU''s have less or other capabilities
