Update: I was bothering Roger off-list and he helped to figure out that the problem with X11 is closely related to nvidia-driver (the one from x11/nvidia-driver port). There's no solution how to make it work so far. Roman Bogorodskiy pgpHtEZXu_jj8.pgp Description: PGP signature

Note that it instantly panicked if the Dom0 has 8GB RAM which may relate to the 4GB mentioned in the patch.

It should be, although I had issues while using the vesa driver with a FreeBSD Xen Dom0, mainly because Dom0 doesn't have access to the BDA and EBDA, I'm working on fixing this in Xen upstream. My setup is as follows: - Intel i5-4690 that supports IOMMU: $ sudo acpidump -t|grep DMAR DMAR: Length=128, Revision=1, Checksum=90, $ - vm.max_wired=-1 in /etc/sysctl.conf - xc0 /usr/libexec/getty Pc xterm on secure in /etc/ttys In loader.conf I have: xen_kernel=/boot/xen xen_cmdline=dom0_mem=2048M dom0_max_vcpus=4 dom0pvh=1 com1=115200,8n1 guest_loglvl=all loglvl=all console=com1 So you are trying to use the serial console but you are not getting any output? If that's not the case, please drop the com1 parameter and set console=vga. Sorry for confusion, actually 'console=com1' works for me. Initially I didn't realize that it doesn't display kernel messages and after some failed attempts to run startx and hard reboots it took much longer to see a login prompt because I have background fsck disabled. So, 'console=com1' works unless I do 'startx'. I'm not sure I would call it working if you don't get any kernel messages while booting. What happens if you set console=vga? Do you have anything else in your /boot/loader.conf apart from this two lines? With this setup I get my system booted and at some point I can see a login screen. When I type 'startx' the system freezes. Have to hard reboot it to get working again. On which device do you get a login prompt? Is it xc0, ttyv0 or ttyu0? I get a login prompt on ttyv0. BTW, I use the nvidia driver. Another user also reported a similar problem with Xen and X, and it was solved by the following patch: https://people.freebsd.org/~royger/0001-xen-introduce-a-newbus-function-to-allocate-unused-m.patch Could you apply it and rebuild your kernel to see if that also solves your issues?

Can you try to enable sshd and see if the system is still responding? Do you have a serial cable on that box in order to catch any Xen messages? If not, and the system is still reachable from ssh after running startx can you paste the output of xl dmesg?
