Re: [Xen-users] netbsd/amd64 5.1rc4 domU network on XEN4 and current dom0

["Christopher R. K." <Feuerball_%gmx.net@localhost>]

The "new" netBSD kernels don't work with Xen4 and some Xen3 versions. (network 
unavailable, bad disk performance)

Try using a older XEN kernel of netBSD (not the recent ones), then it'll work. 
I haven't managed to boot a new kernel, you may need to try to compile one 
yourself. It does run with Xen4 and 3 alike if you use a old kernel. That's at 
least my experience. (32 bit and 64 bit alike)
