I am trying to get going with CentOS 8.
In the past I would run qemu-system-x86_64 -hda myfile.img

Creating KVM-based VM with virt-manager and virt-install on C7
Hi folks,
for learning purposes I create KVM-based VM with the virt-manager. Later
I get rid of the VM and repeat the "process" again. When recreating the
VM I always enter the same values into the wizard in virt-manager (i.e.
I want to speicfy a given MAC).
I'd like to "automate" this procedure, all of what I do in virt-manager
for creating the new VM, I' d like

Cloud Image building (like CentOS is doing it)
Hello,
I was not able to find information about how CentOS is building its
Cloud Images.
I know packer etc are able to do it, but I am interested in how CentOS
is building its own images as we like to adapt that for our Openstack Cloud.
thanks for any hints

Renaming virtio devices names on CentOS 8 VM guest
I have built a CentOS 8 base image from a kickstart, for use in OpenStack.
This image boots fine but the problem I have is that I can't stop udev from renaming the network device from eth0 to ens<something>.
I have /etc/sysconfig/network-scripts/ifcfg-eth0 with the correct HWADDR defined in it, and have set net.ifnames=0 and biosdevname=0 in the grub configuration, but nothing I have

Virtualization Networking
Hello,
I'm a little confused on which networking option I need to choose when
setting up a VM.
I set up two VMs this past weekend both with NAT. Both able to were
access the internet.
The first one, I created in my / file system but didn't really have the
space so I deleted it.
The second one, I created in /home/kvm, but deleted it as well when I

Easy solution for custom firewall rules- is it possible?
Hello All-
I've looked in several places and haven't found an answer to this
question: is it possible to have libvirt add custom rules to iptables
for virtual network interfaces? I took a look at the "Firewall and
Network Filtering in Libvirt" page and it seems overly complicated for
what I want to do.
Given an interface virbr2 and its network 192.168.4.0/24, libvirt

UID/GID CentOS 6 to CentOS 7
Hi,
we are upgrading some servers from C6 to C7 with a lot of user accounts
on them (UID>=500).
CentOS 7 has MIN_UID/MIN_GID 1000, Centos 6 has 500 in login.defs.
Can I change in /etc/login.defs MIN_UID/MIN_GID to 500 for C7? So I
could just grep the users out from passwd/shadow/group files and append
them to the Centos7 passwd/shadow/group files.
Can this do any damage to CentOS7 later

Libvirt supported qemu-ga commands
Where can I find the full list of libvirt supported qemu-ga commands?
The docs [0] imply virDomainQemuAgentCommand bypasses libvirt and is not
recommended.
I am looking to pass suspend/resume events from the host to the guest
and then have the guest act on this internally. Your help is appreciated.

OT: Backup Question/Solution
Hello,
I want to switch from DVDs as a backup medium to a usb flash drive. I have
been using Mondo but get tired of feeding it DVD+RWs.
I purchased a 128GB flash drive. I can't get Mondo to write to it. I want to
be able to make this device bootable. Do I need it reformat it from a
Windows file system to ext4? I never had to format a blank DVD previously.
Is there a better solution

SCSI drives and Centos 7
Everyone,
about 4 years ago, I tried to install CentOS 6 on a Supermicro server
with SCSI drives using a LSI raid system. I could never figure out or
find a way to make the installation disc of Centos 6 identify the SCSI
drives. The installation disc for Centos 5 identified the SCSI drives
without a problem. I finally gave up on Centos 6 and installed Centos 5
and the system has worked very

Network filters with clean-traffic not working on Debian Stretch

I'm recently stumbled over the libvirt network filter capabilities and
got pretty excited. Unfortunately I'm not able to get the the
"clean-traffic" filterset working. I'm using a freshly installed Debian
Stretch with libvirt, qemu and KVM.
My config snippet looks as follows:

Re: Need help with [virt net-create]
Thanks Daniel.
Why was I trying to do something like this ?
Two reasons
1. I was referring to ( Figure 18.4. Virtual network switch running dnsmasq)
https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/Virtualization_Administration_Guide/index.html#sect-network-protocols

how to add file-based disk space to a guest
hi there,
I'm following these documentations to add a file-based disk volume to
a KVM guest under Centos 6.0 :
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization/chap-Virtualization-Storage_Volumes.html
as instructed, I created a "pool" then a "volume", file-based, e.g :
mkdir /mnt/raid/kvm_pool1
virsh # pool-define-as pool1 dir - - - -
