Maybe adding followings at boot will just work for you: console=3D"comconsole efi vidconsole" comconsole_speed=3D"115200" boot_multicons=3D"YES" boot_serial=3D"YES" These are directly copied from the FreeBSD images in Azure Marketplace. I d= on't have on-prem env. Everything I tested is from VMs in Azure. Now FreeBSD wor= ks on Gen2 Hyper-V for both amd64 and arm64. There seems some issues on larger arm64 VMs (with more than 4 vcpus), due to too much parallelization breaking the dependency at boot time. If you keep = you VM size under 4 vcpus, it is less likely to hit the panic mentioned in Comm= ent 11. --=20 You are receiving this mail because: You are the assignee for the bug.=
