[i]
[i] Base VM is running from Arch ISO
[i]
[i] NEXT STEPS - Complete installation manually:
[i]
[i] 1. Open virt-viewer (should already be open):
[i] virt-viewer --connect qemu:///system archsetup-base
[i]
[i] 2. Login as 'root' (no password)
[i]
[i] 3. Run: archinstall
[i]
[i] 4. Configure with these settings:
[i] - Hostname: archsetup-test
[i] - Root password: archsetup
[i] - Profile: minimal
[i] - Network: dhcpcd (or NetworkManager)
[i] - Additional packages: openssh git vim sudo iperf3 mtr traceroute bind net-tools sshfs
[i] - Enable: sshd, dhcpcd (or NetworkManager)
[i]
[i] 5. After archinstall completes:
[i] - Chroot into /mnt: arch-chroot /mnt
[i] - Edit /etc/ssh/sshd_config:
[i] sed -i 's/#PermitRootLogin.*/PermitRootLogin yes/' /etc/ssh/sshd_config
[i] sed -i 's/#PasswordAuthentication.*/PasswordAuthentication yes/' /etc/ssh/sshd_config
[i] - Set up shared folder mount (9p filesystem):
[i] mkdir -p /mnt/host-scripts
[i] echo 'host-scripts /mnt/host-scripts 9p trans=virtio,version=9p2000.L,rw 0 0' >> /etc/fstab
[i] - Exit chroot: exit
[i] - Poweroff: poweroff
[i]
[i] 6. After VM powers off, run:
[i] ./scripts/testing/finalize-base-vm.sh
[i]
[i] Log file: $LOGFILE
[i]
EOF
info "Waiting for VM to power off..."
info "(This script will exit when you manually power off the VM)"
# Wait for virt-install to finish (VM powers off)
wait $VIRT_INSTALL_PID || true
success "VM has powered off"
info ""
info "Next step: Run ./scripts/testing/finalize-base-vm.sh"
