Description of problem:
Attempting to use an https source for the install.img results in the installation hanging because it cannot verify the ssl certificate due to:

Version-Release number of selected component (if applicable):


How reproducible:

100% if using https source

1. Use virt install to attempt to install from the odcs composes
WORK_DIR=$(pwd)
MIRROR="https://odcs.stream.centos.org/test/latest-CentOS-Stream/compose"
DISK_SIZE=10


virt-install \
    --transient \
    --name=centos-9-stream \
    --ram=4096 \
    --arch=x86_64 \
    --cpu=host \
    --vcpus=4 \
    --os-variant=rhel8.0 \
    --extra-args="ipv6.disable=1 inst.text console=tty0 console=ttyS0,115200 rd_NO_PLYMOUTH" \
    --disk="${WORK_DIR}/centos-9-stream.img,size=${DISK_SIZE},sparse=true,format=qcow2" \
    --location="${MIRROR}/BaseOS/x86_64/os" \
    --serial=pty \

You might want to save "/run/initramfs/rdsosreport.txt" to a USB stick or /boot
after mounting them and attach it to a bug report.


Press Enter for maintenance

Expected results:

install.img should be downloaded and the installation should continue.

Additional info:

If you configure a passthrough proxy (e.g. via nginx) that handles the http/https transition the installation works fine.
