No eth0 on centos 6.2
Just installed centos 6.2. I run and ifconfig -a I see and em1 em2 and lo interface. If I go to /etc/sysconfig/network-scripts, I don't see an ifcfg-eth0. If I run ifup eth0 it comes back with "Device eth0 does not seem to be present, delaying initialization". Anybody have a clue? Thanks in advance.

Advice sought: Virtual Win7 on Centos 6.2
Folks I have a new laptop running Centos 6.2 64-bit. I'd like to put a virtual machine running Windows 7 (licensed), with full audio/video functions, and good response. Which virtual system would you recommend? I can think of KVM, or VirtualBox, or ...? The "good response" requirement pretty much excludes a web-style video presentation. Opinions solicited.

Can't find qemu-kvm
I just installed CentOS 6.2 32 bit today. When I try to start the Virtual Machine Manager I get a error: Packages required for KVM usage The following packages are not installed: qemu-kvm These are required to create KVM guests locally. Would you like to install them now? If I click on the [YES] button I'm told that the packages could not be found in any software source. [root at

high availability ideas
Hi, I'm looking for some recommendations. I need to have some sort of high availability for a set of php & mysql web sites, they must be hosted on 2 servers, in separate data centres and obviously on differrent IPs. I can't use a load balancer because that will introduce a single point of failure making the "distributed setup" useless. I was thinking some sort of

KVM and DHCP
CentOS-6.5 We have a KVM guest running MS-WinV7pro. This guest is joined to an Active Directory Domain. That domain provides DHCP to the members. The KVM guest does not obtain its IP from the domain but from the local host's qemu hypervisor instead. Is there anyway to get around this and have the guest MS-Win OS get its DHCP from the same place as the rest of the domain members? -- ***

Clustering solutions - mail, www, storage.
Hi all. I am currently working for a hosting provider in a 100+ linux hosts' environment. We have www, mail HA solutions, as storage we mainly use NFS at the moment. We are also using DRBD, Heartbeat, Corosync. I am now gathering info to make a cluster with: - two virtualization nodes (active master and passive slave); - two storage nodes (for vm files) used by mentioned virtualization nodes

clustering
Hey folks, I just went through the archives trying to find some info on this but did not come up with much other than it seems there are a few experts here on the list. I have no experience with clustering and have just taken over a Stem Cell Research Lab that has a Grid Engine cluster. I have not yet dug into the details of Grid Engine (only been here a week now) but am just trying to get up

OT: Why VM?
I have been working off and on with Xen and KVM on a couple of test hosts for that past year or so and while now everything seems to function as expected, more or less, I find myself asking the question: Why? We run our own servers at our own sites for our own purposes. We do not, with a few small exceptions, host alien domains. So, while rapidly provisioning or dynamically expanding a

redhat vs centos
I have been reading the threads on here with great ernest about redhat making a move to throw off centos compilations. I read some stories about microsoft wanting to work closer with centos http://www.theregister.co.uk/2011/05/17/microsoft_and_centos/ I have to update to centos 6 due to some needs of clients who need newer mysql and php (and installing them on centos5 was too hard for me).

Q. LUKS or ecryptfs-utils ?
I am now investigating encrypting our IMAP user spool files. Does anyone have experience with handling encrypted data stores using either or both of the subject methods and would care tio share their observations? Which is the preferred method (I know: it depends, but on what?)? What administrative pain does each cause? Our IMAP host is a KVM guest so spinning up a duplicate and simply

a cloud VM under CentOS
Hello everyone, Does anyone know if it is possible to construct a cloud of sorts out of several CentOS machines so as to enable a VM (or several VM's) that would run on top of that cloud and have failover capability? Boris.

iSCSI best practices
Hey folks, I had some general questions and when reading through the list archives I came across an iSCSI discussion back in February where a couple of individuals were going back and forth about drafting up a "best practices" doc and putting it into a wiki. Did that ever happen? And if so, where is it? Now my questions : We are not using iSCIS yet at work but I see a few places

LSI MegaRAID experience...
Hey, anyone using an LSI MegaRAID experienced "disappearing drives"...? We installed 6 new C6 servers, each with a Supermicro SMC2108 (LSI MegaRAID) controllers and 3 PX-128M5Pro SSDs ( RAID1 + hostswap). 2 weeks (and almost no activity on it, since not in production, apart from installation) later, megacli sees (based on the slot numbers): - on one server: only the 2nd disk of the RAID

Patches to enable MTUs >1500 in el5.6 ready for testing.
Hi all, With help from others, I''ve been able to get Olaf''s patch for enabling MTUs >1500 for vifX.y and tapZ devices working. I''ve been able to boot dom0, launch domU and live-migrate without having the bridge''s MTU degrade at any time. Would the Xen RPM maintainers (and others) mind taking a look at the following patches? Kernel part:
