My netplan configuration for Palo Alto VM-Series Software Firewall in Ubuntu KVM Host

Subject: My netplan configuration for Palo Alto VM-Series Software Firewall in Ubuntu KVM Host

Good day from Singapore,

I have just bought a refurbished/used/2nd hand firewall appliance with Intel Celeron J4125 processor, 8 GB RAM and 128 GB SSD for SGD$120 at Boon Keng MRT station (near 7-11) in Singapore on 27 Mar 2025 Thursday at about 6.45 pm in the evening.

After the purchase, I have installed Ubuntu Desktop 22.04.5 LTS in this firewall appliance.

This is my netplan configuration (/etc/netplan/01-netcfg.yaml).

network:
  version: 2
  renderer: networkd
  ethernets:
    enp1s0:
      dhcp4: no
    enp2s0:
      dhcp4: no
    enp3s0:
      dhcp4: no
    enp4s0:
      dhcp4: no
  bridges:
    br0:
      interfaces: [enp1s0]
      dhcp4: yes
    br1:
      interfaces: [enp2s0]
      dhcp4: yes
    br2:
      interfaces: [enp3s0]
      dhcp4: yes
    br3:
      interfaces: [enp4s0]
      dhcp4: yes
      
I have tried adjusting many Linux-KVM hypervisor parameters and virtual machine parameters. In addition, I have also tried reinstalling the disk image and performing factory reset in maintenance mode in the Palo Alto VM-Series software firewall.

No matter what I do, I still cannot login to the Palo Alto VM-Series Software Firewall on Ubuntu KVM Host.

When I try to login to the Palo Alto VM-Series software firewall with the default username of admin, I get the following errors:

Any advice would be appreciated.

Over the upcoming long weekend, I will be reading up the following discussion threads carefully and in more detail.

How the Singapore Government cheated my family of a HDB flat (Draft 22 Aug 2023)

Subject: How the Singapore Government cheated my family of a HDB flat (Draft 22 Aug 2023) It is a Well-Known Fact that government(s) invented mental illness to punish and torture people (and their families) who criticise the government or say bad things about the government. The Singapore Government rewarded my mother with a mental illness (schizophrenia). By leveraging mind control technology, the Singapore Government is able to make my mother hear voices in her head and trick her into believing that her neighbors are scolding her and targeting her everyday. Yes, the Singapore Government resorted to using this trickery. My mother firmly believes that her neighbors are scolding her and targeting her everyday. So we sold off our 1st HDB flat at Bedok North Street 3 and purchased another HDB flat at Yishun without careful consideration, planning and advice. When we moved to the HDB flat at Yishun, my mother still firmly believes that her neighbors are scolding her and targeting her every...
