I have a quad core server in which I want to run 4 virtual servers. On this server I have a 1/2 terabyte raid 1 I have split between the 4 members that have the OS on it. I have raid 5 10 terabyte internal storage running on a 3ware 9690a card. I want to share this storage between the servers without partitioning it. Is this possible? -------------- next part -------------- An HTML attachment

Is there a current best practice for a shared filesystem backend for mailboxes (in my case, all virtual accounts)?? NFS 3/4, GFS2, GlusterFS, other?? In the case of the latter ones, is the use of Director necessary?? Any specific anti-recommendations?? Also, if it matters, I *think* I want to use BackBlaze racks for storage.? Also, I've seen recommendations for the filesystem underneath like

Hi list. Im Running xen on a brand new dell PE 1950 with 146 GB SAS Disk on raid1. The performance on the I/O on the domU is really poor, but in dom0 the performance is great. Any ideas?

I apologize if this is a newbie question, but I have been unable to work out how to do this. I am adding code to my installation on dom0 (running CentOS 5.3) to monitor for hardware faults. If there is an issue, I want to propagate the status to all of the domUs (running CentOS 4.x or CentOS 5) running on the host. What are my options to do this?? Thanks! David -------------- next part

Hi all, I have two centos 5.4 servers that I use to run several windows kvm guests (10). All works ok (more or less) but I have a problem with backups. These windows guests are configured to use lvm partitions as a virtual disks. My problem is when I need to do guests backups. which is the best form to backup and restore these windows guests? Some examples? I see snapshot's lvm

Hello, I'm currently setting up a virtualization infrastructure based on CentOS 5.4 x86_64 and KVM. I want to use LVM because of its flexibility, especially the ability to add more disk space to a guest if needed. We are considering using an hardware RAID1 with BBU as the lowest layer. My question is: where is it recommended to put the LVM? 1. On the host only In that case, the guests

I'm seeing an issue with xend not running a custom network script automatically, but works when I run it manually.

I have a machine with 8 CPU's (2 quad xeons). (Centos 5.4 currently). Currently, I am running 2 domUs. One with 4 CPUs and another with 2. 2 remain unused. I am using routed networking. On the one machine with 4 CPU's, there is a cronjob at 4am which utilizes the CPU/disk pretty heavily. It is rebuilds a mailing list archive (using MHonarc) and rebuilds a search engine index

Hello all fellow CentOS users! I have a working xen setup with 3 paravirt domUs and one Windblows 2003 fully virt domU. There are to virtual networks. As far as I can tell in the paravirt Linux DomUs I have gigabit networking, but not in the fully virt Windows 2003 domU.... Is there a setting for this, or is it not yet supported? I run xen-3.0.3-64.el5_2.3 Kind regards, Coert

I have had great luck with nvidia fakeraid on RAID1, but I see there are preferences for software raid. I have very little hands on with full Linux software RAID and that was about 14 years ago. I am trying to determine which to use on a rebuild in a "standard" CentOS/Xen enviroment. It seems to me that while FakeRaid is/can be completely taken care of in dom0 dmraid whereas with

Hi all, I have problem reaching 1Gbps network speed with dom0 / domU (paravirtualized) on my centos5 installations. The fastest speed I measured in domU was about 800/600 receive/transmit Mbps, dom0 being a bit slower. I'm using bridging (eeither with default xen/centos network-bridge script or with my own scripts assigning vlans to bridges). Is anyone experiencing same network slowdown? Or

I am running CentOS 5.3 x86_64 as my dom0 and CentOS 5.3 on my domU's. On the dom0, I have two interfaces that are bonded and have tagged VLANs. I can get the networks to the domU's by creating a bridge for each of the VLANS (bond0.3, bond0.4, etc). On the domU, the interfaces show up as eth0, eth1, etc. Is there a way to set up the network on the dom0 so my domU's see a single

Hi All, I'm using xen 3.0 on CentOS 5 with VLAN. #vconfig add eth0 100 #/etc/xen/script/network-bridge start vifnum=1 netdev=eth0 bridge=xenbr0.100 I know that after xen 3.2 the procedure of bridge configuration is changed.
