similar to: XEN HVMs on LVM over iSCSI - test results, (crashes) and questions

We are running a 2-node cluster with Debian Squeeze (2.6.32-5-xen-amd64) and Xen 4.0.1 on the dom0 and Ubuntu lucid domUs. We are now using fully virtualized (HVM) vms. In our configuration the dom0 administers to domUs created and run on a SAN box accessed via private network (192.168...). A sample configuration file is pasted below. We have had little or no IO problem with HVMs created and

Hi, we would like to establish a small Lustre instance and for the OST planning to use standard Dell PE1950 servers (2x QuadCore + 16 GB Ram) and for the disk a JBOD (MD1000) steered by the PE1950 internal Raid controller (Raid-6). Any experience (good or bad) with such a config ? thanxs, Martin

Is it recommended to use logical volume management INSIDE a hardware virtual machine domU guest? I was trying to think through the ramifications, and I did not think that the LVM in the master dom0 would be able to handle the partition resizing INSIDE the domU guest should such a necessity ever occur. As a background, the physical machine is running hardware RAID. The dom0 is running LVM.

Hi, I've installed CentOS 5 on a Dell pe1950 with 2 dual port NICS. One of the NIC is an Intel and use the e1000 module. The problem is when the server is rebooted it does no asign the ethx name to the NICs, instead the so assign something like _dev377362... so i dont have networking on the server. Any ideas what is happening and how to solve it? Thanks. -------------- next part

Yeah, I thought about that, and while it's not specifically

Hey guys, I am trying to diagnose a hum in my FXO lines I am using an Adtran 750 with 8 FXO ports. I am getting a pretty bad hum on the line during a call. I have checked the Telco side of the 66 block and there is no hum there so it's my problem to fix. I have tried to lower the gain but that reduces the call volume to much. Where else should I be looking? Setup as follows Dell

We have a 3TB external USB drive that I am trying to attach to some CentOS5 servers. I have tried an older Dell PE1950 and a newer R310 but neither one seems to be able to read the drive. It works no problem on windows servers/workstations and I was able to format with NTFS. I know there are different methods for formatting large disks but this one doesn't even seem to show up as a /dev/

Hello everyone. I'm wondering what other people's experiences are WRT systems becoming unresponsive (unable to ssh in, etc) for brief periods of time when a large amount of IO is being performed. It's really starting to cause a problem for us. We're on Dell PowerEdge 1955 blades - but this same issue has caused us problems on PE1950, PE1850, PE1750 servers. We're running

Syslinux 3.85 is a bug fix and minor new feature release. The biggest change is undoubtedly that gPXELINUX is now considered feature complete, and should be able to be a drop-in for PXELINUX for all uses. Special thanks to Intel Corporation, my current employer, for their support for my Syslinux work. Changes in 3.85: * gPXELINUX: updated to gPXE 1.0.0. gPXELINUX can now do NBP

I''m having some trouble working out how to make the SDL interface for HVM domUs appear. The documentation simply says "it will appear" when you start the domU, but doesn''t state what packages or libraries are needed in order for this magic to happen, or explain how to debug it if it doesn''t happen. All that I''m getting at the moment is a domU (running

Hello gentlemen! I just experienced this weird thing: I have 2 machines (one is a Dell Pe1950 with 2 Xeon 5130, the other is a Fujitsu RX200S6 with 2 Xeon E5645), both run CentoOS 5.6, the DELL has the 2.6.18-238.9.1.el5 while the Fujitsu runs the 2.6.18-238.12.1.el5 kernel. But when I try to do a virsh create with this script <domain type='kvm'>

Dear all, I will setup soon an Infortrend iSCSI SAN device with a raid6 volume and a DELL PE1950 (8 VMs) with a Qlogic iSCSI HBA (server to be duplicated at later time for redundancy). My priorities are: 1) VMs on the iSCSI SAN in order to boot them also by another server if the first one fails 2) performances 3) live migration is a non mandatory option (i.e. I can suffer to shutdown

Thanks to debugging information from Thomas Mieslinger, I have root-caused the failure of chain.c32 in Syslinux 3.85. I have put out Syslinux 3.86-pre1 and Syslinux 4.00-pre33 which fix the problem. I expect to release a Syslinux 3.86 relatively shortly (ideally in the next two weeks), with bug fixes only. I would like to figure out if there are other bug fixes we can get in in reasonable time,
