Booting CentOS 5.5 (KVM) from a second disk
by Daniel Bareiro 24 Aug '10

24 Aug '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all! Doing some tests with CentOS 5.5 on a KVM virtual machine, after doing the installation, I added a second disk. But when trying to boot from it, I get the following error: - --------------------------------------------------------------------- root (hd1,0) Error 21: Selected disk does not exist - --------------------------------------------------------------------- The two disks are Virtio devices that are recognized when booting from the first disk: - --------------------------------------------------------------------- [root@localhost ~]# fdisk -l /dev/vda Disco /dev/vda: 10.7 GB, 10737418240 bytes 255 heads, 63 sectors/track, 1305 cylinders Unidades = cilindros de 16065 * 512 = 8225280 bytes Disposit.

I made sure to modify /boot/grub/device.map with the entry for the new disk: - --------------------------------------------------------------------- [root@localhost grub]# cat /boot/grub/device.map # this device map was generated by anaconda (hd0) /dev/vda (hd1) /dev/vdb - --------------------------------------------------------------------- And the reconfiguration of GRUB on both disks did not give problems: - --------------------------------------------------------------------- [root@localhost grub]# grub --device-map=/boot/grub/device.map GNU GRUB version 0.97 (640K lower / 3072K upper memory) [ Minimal BASH-like line editing is supported.

Need tip on an inexpensive printer for college student using CentOS 5.5
by David McGuffey 24 Aug '10

24 Aug '10

Sending my son back to college with a dual-boot laptop with Win 7 and CentOS 5.5. He uses Win7 to manage his iPod and SW that sometimes issued by a professor for a specific course...otherwise he uses CentOS for everything else. That setup worked well last year, except for printing. He has a low-end Cannon printer that is not supported in the Linux realm. Most of his coursework was uploaded to "Blackboard" and rarely did he have to print anything. On the rare occasion when he had to print a paper/briefing, his work-around was to build the paper/briefing in OO, save in Office 2003 format on a USB drive, boot to Win7, load in MS Office and print to the Cannon printer. I'm looking to clean that mess up for him before sending him back to school. Looking to buy an inexpensive printer he can use on both sides of this laptop. Any suggestions? Dave M

Cannot set MTU != 1500 on Intel NIC

CentOS 5.5 flex == Fedora 6 flex ?
by Julio E. Gonzalez P. 24 Aug '10

24 Aug '10

Is CentOS 5.5 Flex the same as Fedora 6 flex ? Have you seen the package name ? Find this because I need to update my CentOS 5.5 flex for compiling new wine 1.2....but that is another problem.... For example: http://mirrors.hpcf.upr.edu/ftp/pub/Mirrors/CentOS/5.5/os/x86_64/CentOS/fle… http://mirrors.cat.pdx.edu/centos/5.5/os/x86_64/CentOS/flex-2.5.4a-41._*fc6… or just maybe a little bug.... Just reporting.

I have a question about the 389 ds
by sync 24 Aug '10

24 Aug '10

Hi ,all : I am a newbie to here and I also install the 389 ds in our company for managering all users account and passwd . Today , The boss asked me if the ds could set the users vnc screen geometry in the config file . Because the user's computer screen is not the same and have different geometries. If it could , then we were happy that can solve the user's vnc problem . Then , I try to search it via Googling , but have not search the useful information about it yet . I know we can use the ds to set the uid or home directory and so on , can the 389 ds do it ?Or maybe add some atrributes ? Could someone give me some suggestions about it ? Thanks in advance ~

When I open the screensaver windows in the kde, I find that it is blocked . I switch to the gnome, it is the same. Is it some rpm that I do not install it?

Announce list digest ??
by Ron Loftin 23 Aug '10

23 Aug '10

It seems that the past month or so the CentOS Announce list digest has no longer been sent out to the general CentOS list ( this list ) although the CentOS Web site still says that this list is subscribed to the Announce list in digest form. I've been checking, and the announce message does not seem to be getting caught in any spam filter that I use. Is this broken, or am I missing something here ? -- Ron Loftin reloftin(a)twcny.rr.com "God, root, what is difference ?" Piter from UserFriendly
