Virtual host package, command line, I need help
by Bob Hoffman 15 Oct '11

15 Oct '11

I am at wits end with this KVM. It is hard to get the information needed to do this properly with centos 6 and KVM since it is so new and the googling of 'KVM' brings up everything except kernel based virtual machines. What I have done... 1) my cpus have virtualization 2) centos 6, selected 'virtual host' package 3) it goes to command line 4) I have made virtual guests with virt-install, in LVM folders, not images 5) 'cannot display' is all I get from command line The packages installed seem to have many gnome and vnc rpms. (and x-windows stuff too) Virt-manager was installed but only produces errors when run from command line I am unable to get anything past getting the guest running since I cannot open any kind of display. I have been able to easily do this in a gnome desktop, but figure command line is going to be less overhead for the server. I have added --vnc and tried some other things, but for the life of me I cannot figure out how to get a graphic or text install to come up on the local machine to save my life. With all the gnome packages (and there are quite a few) that were installed with the 'virtual host' package I figured something would come up, but all attempts have failed miserably. I am stuck in command line with no way out. I do plan on putting up a step by step video when I finally get one working, but after a few days of this (and seeing hundreds of websites with others having the same issue) I am wondering if anyone has ever got it working and what they did? This is just a pure install of centos 6, 'virtual host' package, command line, yum updated, able to make guests, no video options working for me. what is the magic command to bring up some of that gnome stuff for virt-manager or to just see the install window for a guest?? any help appreciated and most welcomed. Thanks.

PAM unable to dlopen(/lib64/security/pam_fprintd.so)
by Alexander Farber 14 Oct '11

14 Oct '11

Hello the logwatch from my CentOS 6 / 64 bit machine (minimal install, with permissive SELinux) keeps reporting me: **Unmatched Entries** PAM adding faulty module: /lib64/security/pam_fprintd.so: 9 Time(s) PAM unable to dlopen(/lib64/security/pam_fprintd.so): /lib64/security/pam_fprintd.so: cannot open shared object file: No such file or directory: 9 Time(s) I've found this bug report - https://bugzilla.redhat.com/show_bug.cgi?id=656434 But I'm not sure what's the best workaround for me - if I'm just running an Apache (Drupal) + PostgreSQL website? Should I install fprintd-pam (got that from "yum whatprovides") Thank you Alex

c6 xen guest install, golf, and geany
by Mark Pryor 14 Oct '11

14 Oct '11

List, Is it possible to do a text install (<512RAM) of C6 server, with support for X11 forwarding over ssh, and get geany (editor) to work over ssh? I got X11 forwarding to work when I have a full Xfce desktop, but not with a server setup. I would like to golf this... IOW find the minimum number of packages. Any hints or kickstart configs for the needy? -- Mark

pvresize on a cLVM
by Antonio da Silva Martins Junior 13 Oct '11

13 Oct '11

Hi, I'm needing to expand a LUN on my EMC CX4-120 SAN. (Well I already had done it). On this LUN I had a PV of a cLVM VG. Know I need to run pvresize on it. Has anybody done this on a cLVM PV ? I'm trying to rescan the devices, but I can't "see" the new size. And, googling on it I can only find RHEL5.2 responses.

Using SD-card reader? (Lenovo T61/Richo R5C822 controller/sdhci driver)
by Toralf Lund 13 Oct '11

13 Oct '11

Hi I'm trying to access an SD-card using the built-in reader on a Lenovo T61 Laptop running CentOS 5.7. The unit is recognised by lspci: # lspci [ ... ] 15:00.2 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 21) 15:00.3 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev 11) 15:00.4 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host Adapter (rev 11) 15:00.5 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev 11) and a driver is loaded and appears to find the device - from /var/log/messages: Oct 13 09:30:48 i58524 kernel: sdhci: Secure Digital Host Controller Interface driver, 0.12 Oct 13 09:30:48 i58524 kernel: sdhci: Copyright(c) Pierre Ossman Oct 13 09:30:48 i58524 kernel: sdhci: SDHCI controller found at 0000:15:00.2 [1180:0822] (rev 21) Oct 13 09:30:48 i58524 kernel: ACPI: PCI Interrupt 0000:15:00.2[C] -> GSI 18 (level, low) -> IRQ 225 Oct 13 09:30:48 i58524 kernel: mmc0: SDHCI at 0xf8101800 irq 225 DMA But then what?? If I insert a card in the drive, nothing particular happens. I mean, I the status LED on the unit lights up briefly, but there is no automount or anything, and I get no messages in the system log. And I can't find any appropriate devices under /dev. The card is accessible when using WinXP on the same machine...

Centos 5.7 - bridging firewall crash (only since the update) - dmesg output included - Trying to vfree() nonexistent vm area (ffffffff885d9000) ....
by Morgan Cox 13 Oct '11

13 Oct '11

Hi. We have several Centos 5 firewalls in our company - they are all in bridging mode. We updated them to the latest Centos 5.x last night. 4 hours later there was a crash.. (previously it had never crashed - and had been running for at least 1.5 yrs) The crash occurred when someone added a rule, after rebooting it was fine - the thing is it can't have been a bad rule as the first thing the server does is load the firewall (same) rules.. In /var/log/messages I can see:- -------------------------------------------------------------------------------------------- Oct 13 09:27:46 new kernel: Trying to vfree() nonexistent vm area (ffffffff885d9000) Oct 13 09:27:46 new kernel: WARNING: at mm/vmalloc.c:329 __vunmap() Oct 13 09:27:46 new kernel: Oct 13 09:27:46 new kernel: Call Trace: Oct 13 09:27:46 new kernel: [<ffffffff800a8b6b>] sys_delete_module+0x1b3/0x1d4 Oct 13 09:27:46 new kernel: [<ffffffff8005d28d>] tracesys+0xd5/0xe0 Oct 13 09:27:46 new kernel: -------------------------------------------------------------------------------------------- Followed by (a few times) -------------------------------------------------------------------------------------------- Oct 13 09:27:46 new kernel: WARNING: at mm/vmalloc.c:97 vmap_pte_range() Oct 13 09:27:46 new kernel: Oct 13 09:27:46 new kernel: Call Trace: Oct 13 09:27:46 new kernel: [<ffffffff884e7000>] :iw_cm:iw_cm_init_qp_attr+0x0/0xb1 Oct 13 09:27:46 new kernel: [<ffffffff800d3e04>] map_vm_area+0x216/0x306 Oct 13 09:27:46 new kernel: [<ffffffff80001ff8>] _stext+0xff8/0x1000 Oct 13 09:27:46 new kernel: [<ffffffff800d4219>] __vmalloc_area_node+0x134/0x15c Oct 13 09:27:46 new kernel: [<ffffffff800403a4>] load_module+0x961/0x19f5 Oct 13 09:27:46 new kernel: [<ffffffff800a2dfd>] autoremove_wake_function+0x0/0x2e Oct 13 09:27:46 new kernel: [<ffffffff8000e0aa>] do_mmap_pgoff+0x3d7/0x780 Oct 13 09:27:46 new kernel: [<ffffffff8000e2e8>] do_mmap_pgoff+0x615/0x780 Oct 13 09:27:46 new kernel: [<ffffffff800b9c60>] audit_syscall_entry+0x1a8/0x1d3 Oct 13 09:27:46 new kernel: [<ffffffff800a92f0>] sys_init_module+0x5b/0x206 Oct 13 09:27:46 new kernel: [<ffffffff8005d28d>] tracesys+0xd5/0xe0 Oct 13 09:27:46 new kernel: Oct 13 09:27:46 new kernel: WARNING: at mm/vmalloc.c:97 vmap_pte_range() Oct 13 09:27:46 new kernel: Oct 13 09:27:46 new kernel: Call Trace: Oct 13 09:27:46 new kernel: [<ffffffff800d3e04>] map_vm_area+0x216/0x306 Oct 13 09:27:46 new kernel: [<ffffffff80001ff8>] _stext+0xff8/0x1000 Oct 13 09:27:46 new kernel: [<ffffffff800d4219>] __vmalloc_area_node+0x134/0x15c Oct 13 09:27:46 new kernel: [<ffffffff800403a4>] load_module+0x961/0x19f5 Oct 13 09:27:46 new kernel: [<ffffffff800a2dfd>] autoremove_wake_function+0x0/0x2e Oct 13 09:27:46 new kernel: [<ffffffff8000e0aa>] do_mmap_pgoff+0x3d7/0x780 Oct 13 09:27:46 new kernel: [<ffffffff8000e2e8>] do_mmap_pgoff+0x615/0x780 Oct 13 09:27:46 new kernel: [<ffffffff800b9c60>] audit_syscall_entry+0x1a8/0x1d3 Oct 13 09:27:46 new kernel: [<ffffffff800a92f0>] sys_init_module+0x5b/0x206 Oct 13 09:27:46 new kernel: [<ffffffff8005d28d>] tracesys+0xd5/0xe0 Oct 13 09:27:46 new kernel: -------------------------------------------------------------------------------------------- Any ideas what caused this ?

CentOS 5.7 PHP upgrade
by dev＠nkmo.com 12 Oct '11

12 Oct '11

I have 3 servers 2 of which run CentOS 5.5, and one with 5.7. I was able to easily upgrade the PHP version to PHP 5.3.8 on the CentOS 5.5 boxes but was thwarted on the 5.7. Does anyone have any tips for how to get PHP 5.3.x installed on CentOS 5.7?

A SATA backplane likely will have a signal bus connector (Suoermicro server backplanes do) but onboard controllers probably won't supply the other end Built servers definitely will as john points out. Better hardware RAID HBAs probably shoild have the complimentary signal bus connector. Make sure your system builder or supplier gets you the right cable bits - i'm pretty sure they're not universal. - csawyer
