I would expect the system to boot up like it did before I upgraded to xenial
When I try to boot my virtual machine host using a xenial based Xen system (Xen 4.6, linux generic 4.4.0) it crashes immediately.
My system setup is non standard as I tried to fix the dom0 memory using dom0_mem. This is due to this FAQ entry: http://zfsonlinux.org/faq.html#CanIRunZFSForXenHypervisor . I use ZFS for virutal machine disks and other storage.
The systems bios is not updated by manufacturer anymore (2013). The on board graphics card is used.
Shared graphics memory is set to auto. Setting it to 128 MB didn't change anything.
Using a wily kernel 4.2.0 generic or a 4.1.22 mainline kernel works.
Using a mainline kernel 4.4.8 or 4.5.2 also crashes.
A quick google search using the first crash report line leads to this
https://lkml.org/lkml/2015/8/19/366
and this
http://code.metager.de/source/history/linux/stable/arch/x86/xen/
I checked that the two patches that seem most relevant here are present in the ubuntu kernel.
Workaround is to not force a particular amount of memory for dom0 (delete dom0_mem parameter)
