VM migration problems
I may have run into this issue before too, but in my case the VMs ran fine with only 1 vcpu so I booted them that way and left them like that. It was just a few small legacy VMs and I didn't spend any more time on it. Did you try booting with only 1 vcpu?

CLAMD and EXIM - anyone got it working`
Has anyone actually got CLAMD and EXIM working? I've just had a go on a new VPS server without success. The only thing that happened was that my server slowed because clamd was hogging CPU. I have done a lot of googling and all I found was a couple of howto's that said the same thing, and my questions from 2015 which is the last time I tried this. I can get clamd / freshclam etc

Pushing real machines into KVM/Qemu
Hi all, I took a real Core 2 machine (T7200? whose motherboard was starting to die?) running Fedora 29 and dd?d the SSD over to my KVM server, then created a VM using ?create from existing image?. After some tweaking, including setting the disk type to ?SATA? from ?Virtio?, I got it working. Is there a fixed recipe for virtualizing CentOS/Fedora/RHEL instances into running VM?s on KVM/Qemu?

Helo, update is in EPEL repository. on startup, clamd does not further create clamd.sock and clamd.pid clamd service stops without any message - even in debug mode. It's a nightmare.

persistent generic device for tape changer
Hello, mtx and therefor amanda use generic device /dev/sg<x> for tape changer. These devices change on reboot. How to make them persistent? /dev/sch0 and /dev/sch1 seem to be persistent. /dev/tape/by-id/ shows links from WWID to generic device An UDEV rule could help? I have not found any example. -- Viele Gr??e Helmut Drodofsky Internet XS Service GmbH He?br?hlstra?e 15 70565

Panic: file auth-request.c
Hello Dovecot list, We've been running a really old CentOS 5 server with the stock dovecot from yum (1.0.7) for years and years with absolutely no problems. If it ain't broke, don't fix it, or something like that. Well it finally broke, but only due to the server no longer being able to handle the load of the increasing user base (many thousands now, with hundreds of concurrent

Traffic shaping problem
Hi all, I tried last week to do traffic shaping on a production system, object of the exercise was simply to throttle the outgoing traffic. tc qdisc add dev eth4 root tbf rate 300mbit burst 300kb latency 50ms But the server became rather instable, crashing repeatedly without anything in the logs. Can anybody spot glaring mistakes in the tc command above, or tell me what I should have done

CentOS6 xinetd failure
One thing I have noticed on CentOS6 is that rsync via xinetd never works after a reboot. It always takes an additional, post-reboot service xinetd restart to get it going. That has been the same for all revisions up to and including 6.5, and I've seen it on more than just machine. While I don't see such a message on other problem machines, the latest reboot gave me a clue: Dec 9

centos at windows network
Hello everyone. When I try to view the windows network which I connected, the error "unable to mount share list from server" pops up. Once I tuned my firewall off, everything works fine. Does anyone know how to configure iptables in order to don't disable them. My current configuration of iptables is following: # Generated by iptables-save v1.4.7 on Sat Nov 16 11:06:35 2013 *filter

Samba4 questions
I'm a little new to Samba when used as more than just a simple place to mount a single user to a single share, but we're now getting ready to replace our Netware servers with Samba, and I guess that means Active Directory DC. As I read more and more about this beast, I keep finding pages that indicate the samba4 rpms supplied with the Centos/RH distribution are not the full version

ASP running on a Linux Machine
Good morning all, I currently have a website that was written in ASP back in 1999. The system is currently running Windows 2003 Server with MsSQL. Before everyone flames me for being in the wrong place, I was wondering if there is a way to allow centos to run old ASP code? I know years ago this wasn't possible without a program like ChiliASP, but noow I heard rumor that apache might have
