Fedora 18 dom0, no video?
Hi all. I''ve got a situation with Fedora 18 on a dual Xeon E5506 box,
16GB RAM, Tyan S7002 motherboard with the latest BIOS. Because of all
the issues, I''m starting to think maybe there''s something wrong with
the box itself, maybe something strange going on with the BIOS or mobo
resources. Although this box was in service without incident for
about 2 years prior. I

KVM Questions
I have a system with two CentOS 7.1 guests. When I created the VMs I did
not have enough storage space in the default location
/var/lib/libvirt/images so I moved the default location to a directory
/home/vmimages. While this configuration is functional I regret creating
a new storage pool in /home. I would like to create a separate partition
to place the VM images removing them from their

GRUB2 configuration for Xen 4 on Ubuntu Linux 10.04
Hello,
I have installed the Xen 4.1.1 and a working kernel 2.6.32.43 which supports
Xen on a Ubuntu Linux 10.04 LTS. However, I have never successfully booted
the Hypervisor and Dom0. The screen is always black after some kernel
messages rapidly go by. I think that I may pass the wrong parameters to the
kernel or Hypervisor with GRUB2.
Can any one share his/her working grub.cfg for GRUB2 with

Cannot remove old NS record
Hi All,
A while ago I replaced a Samba AD on old hardware with a another AD on
newer hardware. Everything went smoothly including the demotion of the
old AD. However after I did some cleanup DNS records and turned off the
old hardware I noticed that there still was a NS record associated with
the old AD. So I went to the wiki page
https://wiki.samba.org/index.php/DNS_Administration and

snmpd log messages
I updated to CentOS 4.5 yesterday and now I am finding the snmpd daemon
is logging reams and reams of these messages:
May 20 10:40:03 mx01 snmpd[2572]: Connection from - 127.0.0.1
May 20 10:40:03 mx01 snmpd[2572]: transport socket = 12
Is there a way to turn off this useless logging? I am getting these
every 5 minutes (every time MRTG updates my MailScanner statistics).

Help with yum
I just did a fresh minimal install of centos 7 on new hardware. While
playing around with window systems I removed X windows like so:
>yum remove "X Window system"
and then tried to re install
>yum group install "X Window system"
which gives this error:
Maybe run: yum groups mark install (see man yum)

Convert Member Server to DC
I have some hardware running CentOS 7 and Sernet Samba 4.7 that started
out as a member server that I would like to make into a 2nd DC. However
I am having trouble converting it because it seems I am not removing all
the remnants of the client setup. What I thought I would have to do is this:
1.) net ads leave -U administrator
2.) Remove the machine entry on the 1st DC
3.) mv /var/lib/samba

CentOS 6.6 KVM Windows 7 Pro VM Device USB 04e8:6860
I have a CentOS 6.6 system running KVM with a Win 7 Pro VM. Over the
weekend I was playing around with the VM trying to get it to see my
Samsung Note 4. Apparently I removed the phone without removing the
hardware from the VM. Now the VM will not start because Device USB
0438:6860 is not there. I tried to remove the hardware from the VM using
virt-manager but that does not remove the error
