Re: Fwd: [Xen-users] Why creating DomU failed (seems it is due to LVM)

["Zhang Binbin" <binbinzh@xxxxxxx>]

Thanks a lot!

I did simply cp /{root,etc,dev,bin,sbin,var,usr,lib} from Dom0 to DomU with 
some config modification, and mkdir /{home,proc,sys,tmp} in DomU instead of 
clean install.

I'll try to blow away all LVM configs...

Best Regards,
Binbin
