similar to: KVM virtual guest can not use serial port

I just installed CentOS 5.1 on a Dell Vostro 200 (Intel G33) which has a Sunix PCI-Express (x1) 8-port RS-232 card installed. For me it looks like only 4 ports are recognized, but I'm not sure if it's even working with those 4. >From 'dmesg' I see this: ... Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled ACPI: PCI Interrupt 0000:04:00.0[A] -> GSI 19

I have been struggling with setting up two serial ports on an HP/Compaq D512S (Intel P4) under CentOS-5. I am not at all sure why these things were not auto-configured when I initially installed the CentOS system from CDs but they were not. I have found various resources on the web and from them uncovered the setserial utility. What I need from somebody is guidance on how to use this utility to

This really isn't a CentOS specific queation but that is our server OS of choice. I manage a student file server and i would like to add cloud access to it. Basically i would like our students to have access to the same files at home that they have at school. This would allow them to start an asignment at home, finish it at school, and print it off without having to worry about losing their

HI, On a RHEL5 box, i tried to directly run guest which was issued by libguestfs virt-xxx commands as below. But after some minutes, it exited exceptionally. Does anyone also hit the issue or know the reason? #/usr/bin/qemu-kvm -global virtio-blk-pci.scsi=off -nodefconfig -nodefaults -nographic -drive file=ubuntu1204_64_20G_aliaegis_20140811.vhd,snapshot=on,if=virtio -drive

Hello there I have been trying to install HP Storageworks DAT72 on CentOS 5 in vain. On system reboot, neither /dev/st not /dev/sg is available.

I am new to CentOS (coming from Fedora) and I really like it! I am having difficulty getting one of my machines to boot and assign the same designation of eth0 and eth1 to the same nics consistantly. I have an MSI motherboard with 2 nics on the board. Strangely enough both nics report the same MAC address. This is not an issue since I use the computer to route between two different subnets so

I recently purchased a Cyber Power 700 AVR UPS. I installed it just fine and wanted to install NUT to monitor the unit. I searched the mailing list and found a similar post. However, the distro used in that post was different and the unit was slightly different (900 AVR). My server is running Debian Lenny. The Cyber Power UPS is connect to one of the serial ports using the cable that came with

I have been trying to get an EVDO modem to work with Centos 5. I can make it dial out with wvdial only when I'm the root user.

Any help would be appreciated. Debian Lenny x86 ups.conf [ippon] driver = megatec port = /dev/ttyS0

Hi, I'm using SolusVM control panel to create KVM VPS. Suddenly, I can't make any VPS on Host-Node. Their build log says the SolusVM can't read the libguestfs in server. During the debug, I've tried to mount existing VPS using guestmount command and I can't mount the KVM image. Please check here. ============= [root@SG01KVM256-01 ~]# guestmount -i -a

I posted this problem on IRC yesterday. Here are some logs.
