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

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?

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: vblade-persist setup 0 0 eth1 /dev/sda3 vblade-persist start all How to create a CVLM VG with /dev/etherd/e0.0 on each of my dom0s? Including the

I wonder if someone can point me in right directions. I have two dell servers I setup iscsi so I have four 2 tb hard drives and i had used lvm to create one big partiton and share it using iscsi. How I go about assigning sections of iscsi for virtual hard drives . should go about assigning Should I export the whole 8TB as one iscsi and then use lvm to create smaller virtual disk. Or should I

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. Picture: |RAID| |RAID| |DRBD1| <----> |DRBD2| \ / |VMAC| | AoE | |global LVM VG| / | \ |Dom0a| |Dom0b| |Dom0c| | |

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

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

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 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?)

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

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.

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.

Hi everyone! I have 2 hosts + 1 ISCSI device. I want to create a shared storage repository and both hosts use together.

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 clusternode3# dd

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

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.

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
