Best practices to setup XEN running on CentOS 6.4
by PhantomNet 04 Jul '13

04 Jul '13

Hi everyone, I'm looking for advice on the best way to setup the guest disks on a single-server XEN system running on a Centos 6.4 fresh minimal install as the dom0. I currently have a system running a traditional VHD disk image for each guest but I'm having disk I/O difficulties and I am looking to optimize it the best way I can. The host disks are two classic 500GB SATA-III drives running in software RAID. My question is what is the best way to set this type of system up? Using the VHD disks or a dedicated LVM partition? Ideally the host will run a few VM's, development, MySQL/Memcached, and Web Server utilities. My current planned disk layout is to have a host system running a raid'd root 20GB partition, leaving the rest for VM's. Should the remaining block be a complete LVM device and carve that up for VM's, or is there a better "accepted practice" for a setup like this? Thanks

Weird Okular/KDE error - thousand procs spawned
by Kwan Lowe 03 Jul '13

03 Jul '13

Hello all: I'm trying to troubleshoot a strange and repeatable error and not sure where to log the bug report. I subscribe to Linux Journal and download their PDF. The DLJ230.pdf opens in the Okular PDF reader from Konqueror. If I scroll down to the ad for some colo site (www.ovh.com) and click the right side of the page, I immediately start getting hundreds of alerts on the desktop. These all say: www.ovh.com contacted. Waiting for reply... Source: http://www.ovh.com/us/index.html They appear at the rate of about one per second. A "ps -ef" shows hundreds of new processes such as: kwan 27155 24731 0 18:21 ? 00:00:00 kdeinit4: kio_http [kdeinit] http local:/tmp/ksocket-kwan/klauncherT24732.s kwan 27169 24731 1 18:21 ? 00:00:00 kdeinit4: kio_http [kdeinit] http local:/tmp/ksocket-kwan/klauncherT24732.s kwan 27177 24731 1 18:21 ? 00:00:00 kdeinit4: kio_http [kdeinit] http local:/tmp/ksocket-kwan/klauncherT24732.s kwan 27184 24731 1 18:22 ? 00:00:00 kdeinit4: kio_http [kdeinit] http local:/tmp/ksocket-kwan/klauncherT24732. I let it run for a few minutes to see if it would time out but it just keeps growing until I finally kill all the kio_http procs (killall kio_http). It's reproducible on at least two CentOS 6.4 builds. Not sure if it's an Okular bug or something else.

Adding browsers
by Beartooth 03 Jul '13

03 Jul '13

Recently, I put CentOS 6.4 on one of the four PCs I keep behind a KVM switch. I like it a whole lot in most ways, but Fedora has spoiled me : I install almost every browser I can, and generally keep half a dozen or more open, mostly with several tens of tabs open. Iow, I use browsers as I used to use books, back in the Carboniferous when I had a desk in the stacks. Are there ways a subtechnoid can run Arora, Dillo, Epiphany, Konqueror, Midori, Kazehakase, Rekonq, Opera, and Pan on this CentOS -- without falling into the bad old pit of dependency hell? -- Beartooth Staffwright, Neo-Redneck Not Quite Clueless Power User Remember I have precious (very precious!) little idea where up is.

This was our experience as well; changing userids between clam and clamav between updates caused us a lot of avoidable headaches. We switched to epel for clamav because of that one issue. Otherwise we have been very pleased with rpmforge. It will prove a great loss if there is a serious possibility that this resource might fade away. -- *** E-Mail is NOT a SECURE channel *** James B.

Centos 6.4, bnx2 in promiscuous mode does not see packets
by Giles Coochey 03 Jul '13

03 Jul '13

Hi, I hope someone can help me, I cannot seem to get a system's ethernet interface to correctly work in promiscuous mode... I have a Centos 6.4 system with 2 bnx2 interfaces on it. I have set up eth1 in promiscuous mode and am sending traffic to it using the port mirroring configuration on a Nortel 3510-24T switch. The switch reports that it is sending a fair amount of traffic to the mirror port. However, within Centos 6.4, I only see broadcast traffic from the switch: [root@host eth1]# ifconfig eth1 eth1 Link encap:Ethernet HWaddr 00:19:B9:E2:30:AE UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:75 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4800 (4.6 KiB) TX bytes:0 (0.0 b) I have tried various options configuring eth1 via /etc/sysconfig/networking/devices/ifcfg-eth1 Currently it looks like this: DEVICE=eth1 BOOTPROTO=static HWADDR=00:19:B9:E2:30:AE #NM_CONTROLLED=no ONBOOT=yes TYPE=Ethernet #UUID="e753ec9b-fc35-4460-bcd1-87f26f8d1553" IPV6INIT=no USERCTL=no PROMISC=yes I have also tried to manually put the interface in promiscuous mode (as I think PROMISC=yes is deprecated): ifconfig eth1 promisc It shows as being in promiscuous mode via ifconfig...

The HP3000 series of MPE/iX mini computers ran on exactly the same hardware as the HP9000 HP-UX systems, but were priced considerably higher than their HP9000 equivalents. However, one could not simply run MPE/iX on the HP9000 hardware. One had to pay HPQ to come in and run a system utility that reset a flag on the processor to enable that. On the other hand, one could run HP-UX on the HP3000 hardware without requiring any changes. A similar thing applied to processor speeds. HPQ would typically release a family of HP3000/HP9000 processors that differed only in speed. The trick was all the processors in the family were identical other than the firmware settings. The processing speed was throttled by firmware switches that one could pay HPQ to turn off in order to increase usable processor cycles. As far as I could ever discover the clock speed was constant so one paid the same for the electricity and a/c whether one had the lowest or the highest processor speed. Mind you, we no longer deal with HPQ or employ any of their hardware because of these and similar experiences. In fact, HPQ's business practices are what turned our firm over to FOSS and commodity hardware in the first instance (after using HPQ exclusively for 20+ years).

Steam for Linux Fedora 17 -> CentOS 6.x

Can somebody contact "Spot" and ask him if Steam for Linux can be compiled on CentOS 6.x? http://spot.fedorapeople.org/steam/ or will someone try it from src rpm's (same folder)? or is someone willing to take over building the rpm the old fashioned way from https://github.com/xvitaly/steamrpm ?
