Re: [Xen-users] can't boot guests on Debian/Buster with 4.19.0-6-rt-amd64 and Xen 4.11

[Jean-Francois Malouin <Jean-Francois.Malouin@xxxxxxxxxxxxxxxxx>]

Hi,

Looks like it's still the case!
I booted from 4.19.0-6-amd64 (non-RT) with Xen 4.11 and I can't reproduce the
errors I was getting before...

thanks!
