compress raw image
Hi, I need to transfer a local raw image to another datacenter. Is there a way to achieve good compression of this image, I heard of tools overwriting unused space with zeros. Is this a good idea? It's an W2k8 image/NTFS. Thx Rainer

Crypto hw acceleration for openssl
I got roughly the same performance results when I use the openssl speed test with and without a hifn 7956 cryto card Here's what I did: After the card is plugged in, kldload hifn; kldload cryptodev; I got the message: hifn0 mem 0xfc8f0000-0xfc8f7ffff, 0xfc8f0000-0xfc8f7ffff, 0xfc8f0000-0xfc8f7ffff irg 28 at device 3.0 on pci1 hifn0: Hifn 7956, rev 0, 32KB dram, pll=0x800<pci clk, 4x

xen 3.0.0 on CentaurHauls VIA Samuel 2
Was on irc for a bit and I''m looking for confirmation that Xen 3.0.0 will or will not work on a C3-II CPU. Found this thread: http://lists.xensource.com/archives/html/xen-devel/2004-03/msg00088.html Which seems that Sean Atkinson created a fix and patch back in March 2004 http://lists.xensource.com/archives/html/xen-devel/2004-03/msg00119.html But the box below $ cat /proc/cpuinfo

Citrix, Samba PDC experiences.
Hi all, I've dug through the lists and google, but haven't found very much info on using Citrix with a samba PDC. The small number of messages and information I've found, lead me to believe it will work. Does anyone have any first hand knowledge they'd be willing to share? I'm currently involved in rolling out Citrix for proprietary windows apps for remote offices.

HELP: Dose G.729 with IPP only worked on Intel CPU?
Hi, ALL: I install IPP(l_ipp_ia32_itanium_p_4_1_2.tar) and download the speech codeing (l_ipp-sample-speech-coding_p_4.1.008.tgz) then patch it (g729-041103.diff). My CPU is Centaur VIA Nehemiah with 998.715 MHz processor not INTEL CPU. I choose PIII as its CPU type when I modify Makefile under "G729-float". # For PIII OPTIMIZE= -O6 -mcpu=pentium3 -march=pentium3 -ffast-math

Hostname inside lxc container
Hi all, I have installed a CentOS6 lxc guest under a Debian 8.x LXC host. All it is working ok but I can't change the hostname for the centos6 lxc container (it is using the same hostname from Debian host). I have modifyed HOSTNAME under /etc/sysconfig/network and /etc/hosts file, but it doesn't works. Do I need to change anything else?? Thanks.

Any alternatives for the horrible reposync
Hi, I'm currently trying to mirror a couple of yum repositories and the only tool that seems to be available for this is reposync. Unfortunately reposync for some inexplicable reason seems to use the yum config of the local system as a basis for its work which makes no sense and creates all kinds of problems where cache directories and metadata gets mixed up. Are there any alternatives? Some

VIA C3 Nehemiah Locks Up
Hello, I've got an EPIA-M series motherboard in a system that has locked up twice under random conditions. Nothing is logged to the console or logs, the system just hangs. The system is installed with CentOS 4.4 and running the 2.6.9-42.0.8.EL i686 kernel. I am aware that older C3 processors had the CMOV problem, but that is resolved in the later boards (procinfo below). I've seen a

Kickstart and volume group with a dash in the name
Hi, I'm trying to setup the provisioning of new OpenStack hypervisors with cinder volumes on them. The problem is that kickstart doesn't allow dashed in volume group names? I tried this: volgroup cinder-volumes --pesize=4096 pv.02 and this: volgroup cinder--volumes --pesize=4096 pv.02 but in both cases I end up with a volume group named "cindervolumes" on the system.

Only write file if copy on master is present
Hi, I''m trying to find a way to configure the firewall on centos systems using puppet by copying the /etc/sysconfig/iptables file and restarting the iptables service. That part is simple to accomplish. The twist I need to add though is that I only want to do this if a copy of that file for the node exists on the server. If this file doesn''t exists then I want puppet to not

xen 2.0/2.0.1 reboots silently on via C3-cpu
On my lex mainboard with a Via C3 cpu, xen 2.0(.1) reboots (nearly) immediately without any outputs. The same setup/version boots without problems on a via epia M board with a Via C3-2 cpu (Nehemia), having a rather different chipset. Starting with option noreboot, nobiostables doesn''t change anything visible. Is this a known problem? Or just a knowingly unsupported chipset? Have you

[LLVMdev] [PATCH] Do not generate nopl instruction on CPUs that don't support it.
Hi This patch fixes code generation bug - 586-class CPUs don't support the nopl instruction and some 686-class CPUs don't support it too. I created bug 17792 for that. BTW. I think you should also optimize padding on these CPUs - instead of a stream of 0x90 nops, you should generate variants of "lea (%esi), %esi" instruction like gcc. This patch disables generation of

Hostname problem
Hi, I''m trying to get puppetmasterd and puppetd to communicate properly with each other but there seems to be a problem with how puppet determines the hostname of the machine. Both daemons run on the same machine with the hostname "nexus" but when I start puppetmasterd with "puppetmasterd -v -d" I get the following output: ... info: Creating a new SSL key at

Slow RAID Check/high %iowait during check after updgrade from CentOS 6.5 -> CentOS 7.2
The HBA is an HP H220. We haven?t really benchmarked individual drives ? all 12 drives are utilized in one RAID-10 array, I?m unsure how we would test individual drives without breaking the array. Trying ?hdparm -tT /dev/sda? now ? it?s been running for 25 minutes so far? Kelly On 2016-05-25, 2:12 PM, "centos-bounces at centos.org on behalf of Dennis Jacobfeuerborn"
