Hello. Finally I tried to recompile the FreeBSD kernel using the @Elliott Mitchell <ehem+free...@m5p.com> code because I want to boot FreeBSD as domU with Xen installed on my Arm 32 bit Chromebook. Unfortunately it didn't work at all. Maybe I've missed something / I haven't understood well what to do. Please give me some suggestions.
Basically this is what I did : $ created a vm called FreeBSD-13.2-RELEASE-armv7.img with qemu / kvm / libvirt / virt-manager $ within the vm : mkdir /build-xen $ cd /usr $ git clone https://gitlab.com/ehem/freebsd-src.git <https://gitlab.com/ehem/freebsd-src.git?fbclid=IwAR09ukOdBXCR3gJznvHWpnWM8VEZqnX1l4ZMza_7lhoAjfPYAGbvcqwjh94> $ cd freebsd-src $ make KERNCONF=GENERIC TARGET=arm TARGET_ARCH=armv7 buildkernel $ make KERNCONF=GENERIC TARGET=arm TARGET_ARCH=armv7 DESTDIR=/build-xen installkernel $ echo "/dev/xbd0 / ufs rw 1 1" > /mnt/etc/fstab $ nano /etc/ttys (add the line 'xc0 "/usr/libexec/getty Pc" xterm on secure") $ renamed the directories dtb to dtb_ and kernel to kernel_ that are inside the /boot dir of the vm $ copied the directory dtb and kernel from the directory /build-xen to the directory /boot inside the vm $ shut down the vm $ copied the directory /build-xen outside of the vm using this method (in this case I used Linux installed on the Host OS,because the kernel that I'm using on the Chromebook has the kernel parameter related to the ufs2 fs set to off) : on my X64 workstation : # modprobe ufs # sudo losetup -fP FreeBSD-13.2-RELEASE-armv7.img # ls /dev/loop0* /dev/loop0 /dev/loop0p1 /dev/loop0p2 /dev/loop0p5 # mount -t ufs -o ufstype=ufs2 /dev/loop0p5 ./FreeBSD-xen then : # nano freebsd.cfg kernel="/mnt/zroot2/zroot2/OS/Chromebook/domU/freebsd-xen/boot-xen/kernel/kernel" memory=64 name="freebsd" vcpus=1 autoballon="off" disk=[ 'phy:/dev/loop0,xvda,w' ] # nano start-freebsd losetup -fP FreeBSD-13.2-RELEASE-armv7.img xl create freebsd.cfg xl console freebsd # ./start-freebsd Parsing config from freebsd.cfg xc: error: panic: xg_dom_elfloader.c:63: xc_dom_guest_type: image not capable of booting inside a HV M container: Invalid kernel libxl: error: libxl_dom.c:571:libxl__build_dom: xc_dom_parse_image failed libxl: error: libxl_create.c:1640:domcreate_rebuild_done: Domain 1:cannot (re-)build domain: -3 libxl: error: libxl_domain.c:1183:libxl__destroy_domid: Domain 1:Non-existent domain libxl: error: libxl_domain.c:1137:domain_destroy_callback: Domain 1:Unable to destroy guest libxl: error: libxl_domain.c:1064:domain_destroy_cb: Domain 1:Destruction of domain failed freebsd is an invalid domain identifier (rc=-6) I have also tried with kernel.bin : # nano freebsd.cfg kernel="/mnt/zroot2/zroot2/OS/Chromebook/domU/freebsd-xen/boot-xen/kernel/kernel.bin" memory=64 name="freebsd" vcpus=1 autoballon="off" disk=[ 'phy:/dev/loop0,xvda,w' ] # ./start-freebsd Parsing config from freebsd.cfg xc: error: panic: xg_dom_core.c:689: xc_dom_find_loader: no loader found: Invalid kernel libxl: error: libxl_dom.c:571:libxl__build_dom: xc_dom_parse_image failed libxl: error: libxl_create.c:1640:domcreate_rebuild_done: Domain 2:cannot (re-)build domain: -3 libxl: error: libxl_domain.c:1183:libxl__destroy_domid: Domain 2:Non-existent domain libxl: error: libxl_domain.c:1137:domain_destroy_callback: Domain 2:Unable to destroy guest libxl: error: libxl_domain.c:1064:domain_destroy_cb: Domain 2:Destruction of domain failed freebsd is an invalid domain identifier (rc=-6) -- Mario.
