Yes, it is unmodified OL 8.8, and I have not (manually) compiled, or recompiled anything (including supermin or libguestfs)

FYI: The KVM Host was installed/configured using the below process (I mention this since I needed to perform some additional repo/module configuration in order to get libvirt-7 installed):

  # Install the Oracle Linux Virtualization Manager Release 4.4 package
  yum install oracle-ovirt-release-el8 -y
     Required oVirt 4.4 Yum Channels enabled.
     Installed:             oracle-ovirt-release-el8.x86_64   1.0-1.0.3.el8
     Dependency Installed:  oracle-gluster-release-el8.x86_64 1.0-2.el8

  yum clean all; yum repolist

ol8_UEKR6                            
ol8_UEKR7

  # Remove any unwanted repos
  dnf config-manager --disable "ol8_UEKR6"

  # Ensure libvirt-7 package is available
  #   
Disable virt:ol and enable virt:kvm_utils2 (this will make the libvirt-7 package available)
  #  
Ref: https://docs.oracle.com/en/virtualization/oracle-linux-virtualization-manager/getstart/getstarted-manager-install.html#manager-prep-kvm
  if ! yum --showduplicates list libvirt | grep "libvirt.* 7"; then
    dnf -y module disable virt:ol
    dnf -y module enable  virt:kvm_utils2
    yum --showduplicates list libvirt
  fi

  # Make sure all packages are up-to-date
  dnf update -y
  reboot

Then the supermin embedded init process appears to crash.  That's

somewhere probably very early on in this code:

Before I look further at this, is this unmodified OEL 8.7.0?

And you didn't recompile supermin or libguestfs?

 

Rich.

virt-p2v converts physical machines to virtual machines.  Boot with a

live CD or over the network (PXE) and turn machines into KVM guests.
