Re: [Minios-devel] [Unikraft] Unable to run hello-world app on Xen on x86_64

[Ajay Garg <ajaygargnsit@xxxxxxxxx>]

As per 
https://lists.xenproject.org/archives/html/xen-devel/2015-09/msg03864.html,
I added the options.
Please find /boot/grub/grub.cfg attached (generated after running update-grub).

After this, I can see that most of the boot-up logs are NOT seen in
the terminal, and also the following is seen when I do "xl dmesg" :

##########################################################3

##########################################################


However, after I run "xl create -c helloworld.cfg", I get the same
errors on command-line, and absolutely nothing extra in "xl dmesg".
