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''ve been using lvm under centos to create the backing store for domUs and although the performance seems acceptable it has some shortcomings. The biggest of which is the LVM bug which prevents me from removing an lv (it says it is still mounted and it definitely isnt). I thought this was just a centos bug but it appears to be evident in debian and ubuntu too and I really can''t

Hi Everyone, My Xen host has 2 X 1TB hard drives in a RAID1 setup. If one DomU starts to dd a 5GB file (A ran it in a loop as a test), access ssh on the other DomU becomes very slow. Is this normal?

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

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

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

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

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 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

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 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

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

Hello, we are using 3.4.3 from Gitco.de on 64bit Centos 5.8 and we have PV guests 64bit. According to described security bug we are in danger. What do you suggest? Wait for gitco update or build xen own with patch? Br Peter

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

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 "Hypervisor Console",

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

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 \

Hi all, I am running Xen 3.2-1 / 2.6.18 on Debian Etch (Dom0). I setup a Dom0 with several DomUs (Linux). Each DomU disk is a LV partition. I have been seeing a few mails about backups and LVM and just wanted to make sure that what I am doing is correct. Each DomU with a database has a cron that dumps the db with mysqldump. Later on, Dom0 will do an LVM Snapshot of all DomUs and then do a

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.

Hi Everyone, As some of you are aware, I''m a very security paranoid person. I guess this is a good way to be :) Anyway, is the 3.4.x branch of Xen still "supported"? By supported, I mean are security and bug fixes still being developed? Or is everything moving to 4.0? I''ve set up some Xen infrastructure using Xen 3.4.2 (due to upgrade to 3.4.3 in a couple of
