libvirtd will stop after 2 minutes (by default) if there is no domain running or client connected to it, this is normal (it will restart when needed).

Which OL version are you running and which libvirt/kvm stack is it?

The Oracle stack (when you use the Oracle KVM repos) won't run rootless by default, and the build scripts won't run as root...
The easiest is to run the kvm utilities from the standard repos (BaseOS / AppStream)

[nkm269]

cat /etc/os-release
NAME="Oracle Linux Server"
VERSION="8.10"

libvirtd --version
libvirtd (libvirt) 8.0.0

uname -r
5.15.0-307.178.5.el8uek.x86_64

i just installed
dnf module install virt
dnf install qemu-img libguestfs-tools virt-install
dnf install zip # For UTM images

on standard OEL 8 version

not sure if i run opc user it immediately fails wih this error but with root it runs for some times and it throws that error

[nkm269]

i just followed instructions in this
https://github.com/oracle/oracle-linux/tree/main/oracle-linux-image-tools

[nkm269]

any idea what to do todebug the issue ?

[AmedeeBulle]

You might have the Oracle KVM repos enabled.

See the KVM User's Guide, and how to switch from the Oracle stack to the default stack

[nkm269]

i tried switch the default stack.. but not sure why it is failing in running as opc user .

[AmedeeBulle]

I am not sure what happens with your installation.

I just spawn a new OL8 instance on OCI (which I assume is what you have)

The only thing I did was

sudo dnf module install -y virt
sudo dnf install -y  qemu-img libguestfs-tools virt-install
sudo dnf install -y git

And the install starts without issue

[nkm269]

@AmedeeBulle
i think the issue running virt tools as sudo

[opc@hypnode4 oracle-linux-image-tools]$ virt-install
ERROR Cannot recv data: Connection reset by peer
[opc@hypnode4 oracle-linux-image-tools]$ sudo virt-install
Using default --name vm1
ERROR
--memory amount in MiB is required
--disk storage must be specified (override with --disk none)
An install method must be specified
(--location URL, --cdrom CD/ISO, --pxe, --import, --boot hd|cdrom|...)

so i updated bin/build-image.sh script to execute all virt-* tools as sudo but it is failing with this error

build-image.sh: SELinux relabel non-root filesystems

libvirt: XML-RPC error : Cannot recv data: Connection reset by peer
libguestfs: error: could not connect to libvirt (URI = qemu:///session): Cannot recv data: Connection reset by peer [code=38 int1=104]

[AmedeeBulle]

There is something wrong with your installation.
Super user privileges should not be required for running virt-install, furthermore some libguestfs tools are known to fail where executed as root.
