RE: [Xen-users] Increasing the number of virtual machines
With the aid of comments here, and some help in #debian (IRC) I have found
out that the kernel I was using for my xen host was compiled without loop
support and hence it would never see more than 4 doms. I didn't compile my
own kernel as I don't have that experience, and getting to grips with
virtualization on its own is proving to be a big enough task.
Many thanks for the comments and advice.
I am now setting up my doms again on the rebuilt server and I will see how
that tests.
Regards
Fred
