I could be a co-/backup-mentor for that.

I've been busy recently moving all the domain management parts of xapi
into a separate daemon, which later can be libxl'ed up. For testing
(and for fun) I've made it understand some of xm/xl config file syntax eg

[root@st20 ~]# xn export-metadata-xm win7 win7.xm
[root@st20 ~]# cat win7.xm 
name='win7'
builder='hvmloader'
boot='dc'
vcpus=1
memory=2048
disk=[ 'sm:7af570d8-f8c5-4103-ac1d-969fe28bfc11,hda,w', 
'sm:137c8a61-113c-ab46-20fa-5c0574eaff77,hdb:cdrom,r' ]
vif=[  ]
pci=[  ]
pci_msitranslate=1
pci_power_mgmt=0
# transient=true

Another goal of the refactoring is to allow xapi to co-exist with domains
created by someone else (e.g. xl/libxl). This should allow a migration to
be done piecemeal, one VM at a time on the same host.

Cheers,
Dave
