I don't think Xen itself is compiled against any libc. I have a
busybox-based (though using glibc right now) initrd which you can use
for your unprivileged domains. You can download it from
http://www.diku.dk/~jacobg/self-migration/
What size does this run at? I am looking to make dom0 as small as
possible, and run all the applications that I require under other
domains, to allow moving them to other machines if required.
I am working on exactly the same thing, though I am using self-migration
in XenLinux rather than the managed migration in Xen. I am already able
to migrate to a minimal Xen-host (the network-facing privileged code is
about 50 lines of C, there is not even a TCP/IP stack running), and I am
currenly working on being able to create new domains using the same
mechanism (almost there).
How does the XenLinux self-migration differ from the Xen managed
migration? What are the advantages of each option. I have only just
started to look into this, so am not stuck to a specific way of doing
things at this stage :)
I am currently on Xen 1.3, because the current Xend is too
resource-hungry and complex for my needs. I am crossing my fingers for
someone to implement the basics of Xend in C, and when that happens I
plan to move to Xen 2.0.
How do the resources used differ? Is Xend currently in python? Is there
a plan to change this? What has been the reasoning behind developing it
in python?
Input and cooperation is welcomed.
I'd love to help. I like the idea of a 'self installing' dom0 that sets
up another control domain, thereby abstracting all the running processes
into unprivileged domains for security reasons. As part of this I will
look to create a HowTo document that details how I acheive this :)
