HP> hmm, I assume that was rc10 to rc11,

Correct, sorry,

HP> - does the guest start if you use 'vserver name start' ?
HP> - if not, what seems to be the cause?

No, the error is:

---- snip ----
vnamespace: vc_set_namespace(): No such process
---- snap ----

HP> - could we get a testme.sh from rc10 and rc11 on your system?

rc10 you've got lately ("[x86] 2.6.15.4-vs2.0.2-rc10 works with FC4"),
rc11 does not show abnorm output, as follows:

---- snip ----
# ./testme.sh -Lv
