Oh, yeah, you're right, it's "make uninstall" :-)
after uninstall 0.8.4 and reinstall 0.6.3, it still won't work.
but one thing I should mention is that while using "virsh start vm01", it reports the same error, saying can't find domain "vm01" with "xenUnifiedDomainLookupByName ".
So I think maybe there is something I'm missing in define a domain.
Would you give me some hints so I can see where I go wrong? Really appreciated

"make clean" won't uninstall the installed stuffs, use "make uninstall"
instead, or you just made a typo? :-)
after that, suggest re-installing 0.6.3 if you are not sure if it's injured.
