Hi,All
I've solve this problem by doing a
chcon --reference=/var/lib/libvirt/images /vm
this solve selinux block kvm from accessing disk image outside of

[CentOS-virt] KVM guest on a specific disk
I'm deploying my KVM virtualization and I have this question. To get my guest os best performance I would like to install my OS from CD ROM while booting in a saperate disk, say /dev/sda4 then in host os I mount /dev/sda4 as /mnt/vm. So I can install a guest OS by virt-install with synax --import, right? I didn't give it a try yet so I'd like to know if other people have done it successfully. Will this let guest os best performance because it has its own disk rather than just a image file? and will it ocuppy the host running resources less?

[CentOS-virt] KVM network bridge setting on centOS
I have a server that will be hosted in IDC. The Server have 2 network interface card. I would like to set one for host os itself. and the other network interface card as bridge for guest OS. Because I have 3 IP address that will allocate to host os and guest os. The host OS will be centos 5.4. I need ideas about how to set host OS's network. Could anybody post a workable network seting for me? because the Centos Wiki page seems out of date about this part. and also I googling a lot, but most instruction in the internet seems out of date too.

That's exactly the point; maybe it is due to XFS coming from an enterprise-class OS (IRIX) to the open source community. On IRIX, there was a distinctive hardware platform on which IRIX and thusly XFS was run on. When XFS was ported to GNU/Linux, it not only had to deal with different LVM and RAID devices/mechanisms, but also with some hassles when being deployed on 32bit environments, for which it just wasn't designed. So, to sum it up: IMHO it was surely in most cases not XFS's fault when data loss occured, but more due to errors that were made when being deployed (in GNU/Linux environments), be it 32bit issues, (missing) barriering or whatever. It'd be interesting to see some statistics on XFS issues on IRIX vs GNU/Linux. Regards, Timo ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I recently doownloaded and installed the latest RHEL5 rpm from the VirtualBox web site. While it generally works very well, I have been unable to get USB access to work on the guest. This seems to be a very common problem. Many references to it turn up in a web search, but I have not found a solution that works on CentOS 5. I got no response on the vbox-users mailing list either. Can anyone here help? Among the things I tried were various /sys and /proc/bus/usb related fstab and rc.sysinit changes.

Re: [CentOS] CentOS 5.4 x86_64 only detects 32GB RAM while Fedora x86_64 correctly lists 128GB

The 64 bits version of Fedora 12 lists the correct amount of 128GB, CentOS only finds 32GB (and so does Scientific Linux). I would much prefer to use CentOS (most of the software we use is specifically designed for CentOS). Does anyone know what is causing this/how to fix it? Have you checked xm info to see the Xen hypervisor memory info? Maybe it's just the dom0 linux kernel that doesn't have more than 32G, and the Xen hypervisor sees all of it. Anyways, you should always limit dom0 memory to 512 MB or 1 GB to disable Xen memory ballooning. If you boot dom0 with all the (32G of) memory visible to it, and then create VMs, and thus balloon dom0 down to much smaller amount of memory, you'll get all kinds of problems when the dom0 linux memory suddenly is much smaller than it was during boot time. You should always limit and dedicate some amount of memory to dom0.

[CentOS] CentOS DHCP Server
CentOS Community, I need help with a CentOS DHCP server. I have a simple 32bit CentOS 5.3 server running on an Intel chip server in a lab environment with two NIC's. Interfaces: eth0 - Is connected to the Internet using a static public IP address. eth1 - Is connected to a private 10.1.1.0/24 LAN with no other access to the web. Runs DHCP to the internal client systems. Is the default gateway for all LAN traffic to the Internet. Runs iptables as the firewall between the LAN and the Internet. On eth1 DHCP was running with no problems for some time. This lab system sat for months untouched and then we revisited this product/project only to find that DHCP would not start. It gave us this following error: Failed to start dhcpd : Internet Systems Consortium DHCP Server V3.1.3 Copyright 2004-2009 Internet Systems Consortium. All rights reserved. For info, please visit https://www.isc.org/software/dhcp/ Wrote 0 leases to leases file.

Also make sure you are not running HP JetAdmin software, which includes a bootp server. There is no other DHCP server on this LAN or on the public /30 that eth0 connects to (not that eth0 would impact my internal LAN). I saw there were ofcourse many systems updates for CentOS and thought that a might resolve. It did not. I then downloaded many versions of ISC's DHCP and compile and tried each of them from source code. This problems still exists. I have tried even the very simplest of dhcp.conf files and DHCP will still not start. Have I found a bug in the ISC DHCP code? Unlikely. I hope that one of you has run into this before and can help me out. Thanks greatly in advance.

Re: [CentOS] 486 custom kernel
At Tue, 08 Dec 2009 14:02:28 -0500 CentOS mailing list centos@centos.org wrote: Hi all, Is it possible to take the 686 CentOS 5, install that in virtual machine, install a custom kernel that is the 486 flavor, take that image and put it on a 8G CF card - insert that into a small form factor 486 class machine and have that work? Will this small form factor 486 class machine be on the public internet network? If not (and thus not needing any current security patches, etc.), you might consider install RH 7.3 on it. RH 7.3 includes a *stock* i386 2.4 kernel (RedHat never built i486 kernels and I am not sure if anyone else bothered to either). I would also guess that the small form factor 486 class machine probably is NOT going to have modern I/O items, so you *probably* won't need any new kernel modules (eg SATA or fancy video or sound or network cards, etc.). I fould a set of RH 7.3 CDs on-line (*one* of the old mirrors still has it on line: ftp://mirror.atlantic.net/pub/redhat-archive/7.3/ And I snarfed the ISOs to my server: ftp://ftp.deepsoft.com/pub/RH7.3/iso/i386/ (I have an interst in using RH 7.3 on old '486 boxes and use them as model RR control nodes.) I am hoping the extra instructions in a 686 (MMX, SEE etc) are not used by any libraries Only some libraries (glibc for one, but it is available in several 'flavors', I think including a vanila i386 flavor). that I would be using (just standard stuff) and the new 486 compiled kernel would not be using those instructions either. Can this possible work? I am hoping to not use debian i386 basically. Since various packages that would be installed on a 686 machine would be built for the 686 arch, you can't just copy the image of the 686 install onto a 486 system. You'll need to do a re-install to a 486 target. You can rebuild the kernel on the 686 (virtual or otherwise) and I believe all of the *.i686.rpm's are available as *.i386.rpm's. Somehow you will need to hack things at the install level to force a plain i386 install. You might need to hack anaconda and insert the i386 kernel or some such. Or do a careful downgrade of all of the i686 packages to i386 packages (in addition to the kernel itself).

Could possibly check to see if there is indeed another dhcpd daemon running. Something along the lines of 'netstat -patun | grep dhcp' or look for anything listening on UDP:68, iirc.
