Hi,

I have a similar problem, as mentioned here https://github.com/mirage/mirage-skeleton/issues/251. Maybe they are correlated.


Best,
Vittorio

Hi,

I installed Xen on Ubuntu 16.04 Server, which runs as a VM in VirtualBox 5.2.6 
on macOS.
I think nested virtualization (running Xen within another hypervisor) is not 
very well supported (perhaps someone more familiar with the current state of 
nested virt in Xen can comment more?), and I'm not surprised that there are 
problems with a unikernel that tries to use network resources there.  I would 
recommend trying with a hypervisor running directly on hardware, not 
virtualized itself.
FWIW that used to work, at least for me. I will admit to not having done it 
recently though, so perhaps somewhere in changes to OSX, Virtualbox, Xen and 
Mirage over the last year or two, things have changed.
Indeed — this doesn’t look like a nested virt crash to me, since it has 
attached to netfront and is crashing quite late in boot.  I’ll see if I can 
reproduce it later, as I’m suspicious that this might be due to a change 
somewhere in newer Xen device models.  It’s hard to tell without a gdb 
backtrace for sure where it’s crashing.
