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 Nicolas

Renaming virtio devices names on CentOS 8 VM guest
I have built a CentOS 8 base image from a kickstart, for use in OpenStack.

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 installs

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. [0] https://wiki.libvirt.org/page/Qemu_guest_agent

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
