C5 XEN domain not startable
by Dave Stevens 31 Mar '10

31 Mar '10

Hi, I have a Centos 5 box with dom0 and several domUs and one of them is not runnable. I ran updates several days ago and the update included a kernel update so I used virt-manager to reboot. But it won't book. It shows as not running and when I try to run it I get a dialog box with this: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 498, in run_domain vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 573, in startup self.vm.create() File "/usr/lib64/python2.4/site-packages/libvirt.py", line 287, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: Unknown failure I don't know what to do about this. Anyone have ideas? Dave -- "It is no measure of health to be well adjusted to a profoundly sick society." Krishnamurti

IBM Touchscreen
by Janez Kosmrlj 31 Mar '10

31 Mar '10

Hi, i have some old IBM USB touchscreens, that insist on not working correctly under CentOS. I tried to use the 3m driver and the elousb driver, but none of them work. The touch part works out of the box witohut any drivers, but i can't find a way to calibrate them The y axis is inverted and the X axis is a bit off. Here is the output form lsusb: Bus 003 Device 002: ID 0596:0001 MicroTouch Systems, Inc. Touchscreen We also have some new models from IBM and they work with elousb driver. We also have some 3m monitors which work with the 3m drivers. Regards, Janez

selinux on xen virtual machines
by lhecking＠users.sourceforge.net 31 Mar '10

31 Mar '10

I rebuilt my xen host with the 64-bit OS and am in the process of recreating the guests, both 32 and 64 bit. I use a kickstart installation with virt-install, and so far none of the installation attempts has completed. Anaconda indicates installation should take about 2-3 minutes, but when it comes to installation of selinux policies, it just sits there, and I have no idea what it's doing. No progress 15 minutes later, and it doesn't make a difference whether I disable or not selinux in the kickstart configuration. What's the best thing to do in this situation? CentOS 5.4 with all current updates. --------------------------------------------------------------- This message and any attachments may contain Cypress (or its subsidiaries) confidential information.

Disable specific LUN on a SCSI bus
by Lorenzo Quatrini 31 Mar '10

31 Mar '10

Hi all, do you know if there is a way at boot time do disable specific LUN's on a SCSI bus of a particular controller? I'm trying to write an udev rule, but it seems that the system ignores the "vendor" model/name of the controller... For example: I want to disable /dev/sdb; so I gather some information with udevinfo -a -p /sys/block/sdb and I try to use them to write /etc/udev/rules.d/10-custom.rules ID=="?:0:1:0", BUS=="scsi", DRIVER=="sd", SYSFS{model}=="DDYS-T36950N ", SYSFS{vendor}=="IBM ", OPTIONS="ignore_device", OPTIONS+="last_rule" I put the "?" on the ID field because I know that the order of the controller can change (a kernel update could trigger the switch); also I tried with and without the spaces at the end of vendor and model: no change Where am I wrong? It is a different way of doing this? TIA Ciao Lorenzo

very strange
by cahit Eyigünlü 31 Mar '10

31 Mar '10

i have 2 servers in a datacenter and each of them has 2 virtual machines one is linux the other is windows of wirtual machines. when i want to transfer my ip addresses between theese servers , for ex: let me say main server 1' guest windows : A main server 1' guest CentOs: B main server 2' guest windows : C main server 1' guest CentOs: D when i handle an ip of any computers ip in network from A or C it directly handles, no matter where the ip routed from cisco router :D but when i want to handle any computers ip in network from B or D it never get the ip from other source :D how this could happen :)

Define HTTP proxy system-wide (Squid and Squidguard) ?
by Niki Kovacs 31 Mar '10

31 Mar '10

Hi, I'm currently configuring Squid and Squidguard for filtering web access in a public computer room. So far, everything works fine. I know how to configure Firefox to use a proxy, but there's no way to protect that configuration, e. g. a more knowledgeable user might circumvent this configuration. Is there some way to configure an HTTP proxy system-wide? Cheers from the sunny South of France, Niki

Re: [CentOS] mounting gfs partition hangs
by sandra-llistes 31 Mar '10

31 Mar '10

Hi, I'm not a GFS expert either :-) In fact, I erased all the configuration of the cluster and try to do it again from scratch with luci/ricci configuration tools (perhaps I did something wrong last time) mount -vv gives the following information: [root@node1 gfs]# mount -t gfs -vv /dev/home2/home2 /home2 /sbin/mount.gfs: mount /dev/mapper/home2-home2 /home2 /sbin/mount.gfs: parse_opts: opts = "rw" /sbin/mount.gfs: clear flag 1 for "rw", flags = 0 /sbin/mount.gfs: parse_opts: flags = 0 /sbin/mount.gfs: parse_opts: extra = "" /sbin/mount.gfs: parse_opts: hostdata = "" /sbin/mount.gfs: parse_opts: lockproto = "" /sbin/mount.gfs: parse_opts: locktable = "" /sbin/mount.gfs: message to gfs_controld: asking to join mountgroup: /sbin/mount.gfs: write "join /home2 gfs lock_dlm gfs-test:gfs-data rw /dev/mapper/home2-home2" ... And hangs at that point (On the other node it happens the same) I tried it turning off the local firewalls on the nodes and they reached each other without problem with pings. Also, there are no more firewalls between them. The new configuration is more simple: [root@node1 gfs]# more /etc/cluster/cluster.conf <?xml version="1.0"?> <cluster alias="gfs-test" config_version="6" name="gfs-test"> <fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/> <clusternodes> <clusternode name="node1.fib.upc.es" nodeid="1" votes="1"> <fence> <method name="1"> <device name="test" nodename="node1.fib.upc.es"/> </method> </fence> </clusternode> <clusternode name="node2.fib.upc.es" nodeid="2" votes="1"> <fence> <method name="1"> <device name="test" nodename="node2.fib.upc.es"/> <device name="test" nodename="node2.fib.upc.es"/> </method> </fence> </clusternode> </clusternodes> <cman expected_votes="1" two_node="1"/> <fencedevices> <fencedevice agent="fence_manual" name="test"/> </fencedevices> <rm> <failoverdomains/> <resources> <clusterfs device="/dev/home2/home2" force_unmount="0" fsid="3280" fstype="gfs" mountpoint="/home2" name="home" self_fence="0"/> </resources> </rm> </cluster> Finally, I reformatted /dev/home2/home2 with the following command that gave no errors but it doesn't affect the final result: gfs_mkfs -O -j 3 -p lock_dlm -t gfs-test:gfs-data /dev/home2/home2 Thanks, Sandra PD: I append an strace but I can't see anything useful.

Keyboard problems on Centos 5.4
by Darmath 31 Mar '10

31 Mar '10

I installed CentOS 5.4on a WMWare Server virtual machine that's running on win7. Everything seems to work fine except I get a shit load of error messages from the console along the lines of when I type on the keyboard: atkbd.c Unknown key released (translated set 2, code 0x81 on isa0060/serio0). atkbd.c Unknown key pressed (translated set 2, code 0x81 on isa0060/serio0). *atkbd*.*c*: Use '*setkeycodes* e059 <*keycode*>' to make it known. NB: the code's change and there doesn't seem to be any particular codes Is this because i'm running centos on the VM? Any ideas how i go about actually fixing this? I've had Centos dual booted with winxp on this same hardware previously without any problems. Being unfamilar (having not used Centos much) I don't really have any idea where to start to resolve this.
