[Xen-users] Xen domu crash on boot

[Billy MacAllister <bill@xxxxxxxxxxxxx>]

I rebuilt a xen server today, first using the standard packages in 
Ubuntu 18.04 and then using Ubuntu 16.04. I went back to 16.04 after I 
was unable to get a domu's to boot successfully.  I have another
Xen host running successfully on 16.04.

I am building pv domu's using xen-create-image.  The command line I am 
using is:
/usr/bin/xen-create-image --hostname=somehost.com --ip=10.0.0.44 \
 --memory=2Gb --genpass=1 --size=32Gb --pygrub --swap=2Gb  \
 --role=udev,cz-stretch --dist=stretch --arch=amd64

I was getting exactly the same behavior on the Ubuntu 18.04 system, i.e.
domu's crash on boot. What should I try?

I have been able to build a buster domu on the 16.04 system, but there 
appears to be some entropy problems with it. I have to wait several 
minutes after bootimg the domu before it will accept logins.  Once I see 
the following message on the console I am able to login.
[  207.744797] random: crng init done
[  207.744814] random: 7 urandom warning(s) missed due to ratelimiting

This appears to be a problem with newer kernels.  Does anyone have a 
work around?
Bill
