xen FreeBSD 14.3-RELEASE-p2 GENERIC amd64 - boot loop

[override]

Hi,

I'm trying to configure FreeBSD as Xen host. It is my first meeting with Xen hypervisor. I fallowed Handbook with minor modification (as I presume) to xen_cmdline

/boot/loader.conf

kern.geom.label.disk_ident.enable="0"
kern.geom.label.gptid.enable="0"
cryptodev_load="YES"
zfs_load="YES"

if_tap_load="YES"

xen_kernel="/boot/xen"
xen_cmdline="dom0_mem=4096M dom0_max_vcpus=4 dom0=pvh guest_loglvl=all loglvl=all"

to /etc/rc.conf I had added

xencommons_enable="YES"

and network configuration besides changes made by FreeBSD installer.

Boot process looks like this, maybe it will be helpful

I'm not seeing any errors or crashes. For me, it looks like it just stops.

I'm looking for any suggestions

P.S. I have checked bios configuration and I have enabled IOMMU and SVN Mode. I have disabled 4G Decoding, but it nothing changed. I have tested UEFI and Legacy with the same results

Try verbose boot, perhaps it would have more info...
Also, try to enter the online debugger with Enter ~ Ctrl-B sequence.

After enabling verbose boot I have noticed errors/warnings abount AE_NOT_FOUND

xen cpu23: unable to execute _PDC - AE_NOT_FOUND

I will try with online debugger. It will be my first time with this tool. Meanwhile, it is all I have.

P.S. As motherboard, it is ASRock Rack X570D4U
